Shooting into the blue… (Lanzarote)

Back in June, I had the opportunity to visit Lanzarote with my girlfriend.  I wasn’t sure what to expect, having not been to the Canaries before, but I did some research and found out that the diving is supposed to be amongst the best in the North Atlantic. I therefore persuaded my girlfriend that it was time for her to learn to dive too – and promptly packed my cameras and gear for a good-old wildlife photography trip…

As you may have seen in some earlier entries on this site – underwater photography is a growing passion of mine, and one that I’m only beginning to get to grips with.  It’s still something which it is possible to make your first inroads into without spending a fortune. Indeed, I picked up one camera at the airport, a Nikon Coolpix S33, for about £70.  This little camera is officially waterproof to 10m, and in the clear waters of Lanzarote, seemed very capable.  I can also say that mine kept the water out to at least 30m, but the pressure stops the buttons working beyond about 12 to 15m.  It makes it ideal for snorkelling and beginner divers though.

Taking photos underwater often causes trouble with light, as there is nearly always a blue cast to images (which can be fixed on a computer fairly easily) – but you also want to try and catch the light the right way.  Hopefully you will be able to get yourself into a position for the light to reflect off the fish or corals, or you can shoot up with the light behind your subject.

When going a little deeper, however, I had a Panasonic DMW-MCTZ35 Lumix Marine Waterproof Case for a TZ35.  This was an excellent combination of a very effective dive house and compact superzoom camera with a specific underwater mode.  The total cost is higher at around £300 or higher – but it’s still relatively cheap for a combination capable of diving to advanced diver depths.

If in Lanzarote, and you get the chance to visit the dive site called the Cathedral, it is well worth a look!  Get right inside and shoot out towards the light to create a silhouette as your dive buddy swims across the mouth of the cavern.

I should put out an extra special mention for the fantastic team at Manta Diving, Lanzarote – who looked after us fantastically on our trip.  Also – please don’t think the only things to take photos of are underwater!

Travel the world: Make great memories

Like so many photographers, I love to travel and to photograph the world around me.  Whether close to home or in distant lands, there’s nearly always something worth gazing at in wonder, just taking it all in.

Staring at things will hopefully give you an eye for what you like in an image – and if you’re like me you will then want to take a great photo as an aide memoire or souvenir of the scene, and how you felt at the time. (I have no idea why English people need to remember everything in French!)

As this blog is generally about making photography cheap, I’m not trying to suggest that to take great photos you need to do lots of expensive travelling.  It’s simply that, if you are travelling, you should take the time to enjoy your photography, no matter how cheap or expensive your gear is.  The photos you take on your travels will naturally feel more interesting and exciting to you than the more everyday shots near your home – and travelling throws up some wonderful opportunities to capture great images.

I thought it might be worth sharing a few ideas for things to try when travelling, which are free, cheap or at least well worth the expense.  They’re all things that work for me, and hopefully might work for you too!

You don’t need to travel far to get some great photos

It’s always struck me as weird that people will take a camera on holiday and take photos of absolutely everything, but when they go on a day trip to fantastic places in their home country with family and friends, and not bother taking a camera at all.  Take a camera with you everywhere – it’s great practice.

Don’t be afraid of including friends and family

Having photos of and with the people closest to you is really important.  Sure – you probably can’t sell them and enter them into competitions, but you can pass them on through the generations and get some great moments. Plus they will actually mean something to you – and you will therefore look back at them again and again.  You can still take some beautiful photos (even with your ugly mates and relatives in!)

Take a boat trip…

There’s so much to see at sea (or on lakes and rivers) and the time you spend sitting and staring means you notice things and take photos that you might otherwise have missed running around.  Nearly everywhere you go on holiday, it’s possible to get a boat, and they hardly ever cost much.  Just be prepared to jostle your way past other tourists!

Set yourself a challenge… (because the best things in life are free)

Practice makes perfect, or at least doing something over and over again statistically increases your chances of getting it right.  This is a key theme for me in photography – and I think a helpful tip for anyone trying to take good photos on a tight budget.

It’s very easy to get blown away or intimidated by some of the truly awesome photos out there taken by professionals, or occasionally by a lucky amateur in the right place at the right time.  A key thing that can be learned from all of these photos, though, is to put yourself in the right place, at the right time.  Also, know what to do when you find yourself there.

…a traveler from the tropics may be amazed at the site of a swan – which are common-as-muck in temperate countries, but completely absent from Africa and huge swathes of Central and South America and Asia.

I thought today, it might be fun to think about wildlife photography.  This is a real passion of mine, and I try to take photos of the animals I find around me all the time.   Many of mine lack the finesse and perfection of the work of the experts, but I think I have managed to get some nice images over time and this is almost certainly because I repeatedly set myself challenges and will carry on trying until I’m pleased with the result (and will carry on trying to get better even after that).

To make an obvious statement; you can categorize wildlife photos into two sorts: Photos of exotic animals where the simple inclusion of the animal itself makes the subject interesting and photos of everyday animals where you need to capture something more to keep the viewer interested.

If we examine this statement closely, though, how true is it really?  After all, the animals which are exotic to you will seem everyday to someone else.  The locals in Thailand (or even the South of France!) always laugh at me for spending my time taking photos of lizards, of which we see very few in England but are literally everywhere, there.  Similarly, a traveler from the tropics may be amazed at the site of a swan – which are common-as-muck in temperate countries, but completely absent from Africa and huge swathes of Central and South America and Asia.

On this basis – I would recommend you set yourself a challenge and get out near where you live regularly and try and shoot the animals that you find.   There’s no need to worry too much about what equipment your using.  True – to shoot distant subjects you will need a long lens and to shoot really close-up you will need some sort of macro kit.  This can be a lot of fun (and I’d encourage you to try it) but most animals can be shot with just a compact camera or a smart phone and a bit of patience.  Just try to get yourself into the right place and learn how to get close to the animals, whether domestic or wild.  After all, taking a photo of an animal is free!

…the time you spend practicing on every-day animals will mean you get better shots of the ones that excite you.  You might even get one of those magic shots that makes the ordinary look extraordinary.

If you get the chance, also try taking photos of animals at the zoo, or somewhere like Longleat safari park, or just at a farm.

In some cases, its a question of quietly “stalking” and not startling an animal. In other cases, it might be a case of attracting it over. Remember, a lot of animals have very sharp hearing and eyesight, so even if you’re shooting from a distance, sudden movements could scare them off.  A hint, for example, is never make eye contact with a wild deer…

The great thing about doing this near your home and with your local wildlife is that you will learn skills which will stand you in good stead when you’re face-to-face with a more exotic animal, on holiday, or in those great chance encounters, like a barn owl sitting in your garden fence.  So the time you spend practicing on every-day animals will mean you get better shots of the ones that excite you.  You might even get one of those magic shots that makes the ordinary look extraordinary.  (Check out the British Wildlife Photography Awards website for some great examples).

Sink or swim – the key to success under water

Perhaps you’re one of those people who watched Jaws and has decided it still isn’t safe to get back in the water, or perhaps, like me, you watched it and thought “wow that’s cool!”

If the latter is the case, you’ll probably spend half your life trying to find an excuse to jump in the sea, into a lake or even into a swimming pool with a pair of goggles on to find out what’s going on below the surface.  And when you do, you probably want to get some good shots of the stuff you see (whether it’s your friends and family playing in a pool, a crab, a brightly coloured fish or jaws).  So how do you do it, and how much will it cost?$

“you’ll probably spend half your life trying to find an excuse to jump in the sea, into a lake or even into a swimming pool with a pair of goggles on to find out what’s going on below the surface.  And when you do, you probably want to get some good shots of the stuff you see…”

As ever, it will cost as much as you want to spend.

It’s clear that for the very best, super-sharp and well exposed images at depth, you will need an expensive camera with high ISO (light sensitivity) capabilities.  This may be a custom designed underwater camera or a specialist, dedicated underwater housing for a DSLR.  This, though, is the realm of the scuba diver, and nearer the surface (down to around 10m) you can get by with some pretty cheap and basic gear:

Underwater shooting with zero preparation

If you’re not a regular scuba diver, the times when you’re most likely to want to take photos under water are when you’re on holiday.  You might be by the sea in Cornwall, or in the Mediterranean or on the Pacific coast.  Wherever the sea is, there is the desire to jump in it and boat on it.

However, most cameras are not waterproof. Take it from someone who knows, you don’t want to take a decent camera out, even on a boat, without protection if you want it to come back working.  Ideally, you want to think about this before you go away, so that you can get a waterproof camera or some sort of housing.   The great news is, though, even if you forget, nearly all beach resorts and shops sell disposable waterproof cameras. Some of them can even be reused!

Waterproof disposable camera
A waterproof disposable camera – everyone’s friend on holiday.

This wouldn’t be a very helpful website, though, if I just said “buy a disposable camera” and everything will be alright.  If you want to get the best from your photos, things aren’t quite that simple.

The first thing to point out, is that disposable cameras aren’t that cheap.  True, to buy they’re cheaper than a digital camera, but they still tend to be over £10 and are only single use (or you will at least need to buy film to reload them) and you have to pay to get your  photos developed.

Here are a few pointers on getting the best results and best value for money:

  • So long as it works, there’s not much point worrying about brand – cheap ones tend to work just as well as more expensive ones.  They are all fixed focus and generally don’t have a flash.
  • Check the speed of the film in the camera – it’s unusual to find ISO 1600, but 800 and 400 are both common. 800 is much more useful, particularly in the sea (swimming pools tend to be better lit with higher visibility).
  • If you can get a re-loadable / re-usable one, do.  They tend to be about the same price, and you can choose to load 1600 film after the first use.  They’re also more environmentally friendly.  Make sure you’re careful with the rubber seals though.  These cameras really are cheap and low quality and not built to last!
  • Pay extra when you get your film developed for a CD with JPGs on it.  It’s only a couple of quid and is really useful because you can then get the best from your photos with some careful post-processing (see below).  If you have a negative film scanner, or know someone who does, this is just as good.
  • Always check the “use by” date.  Chemical film has a shelf life, which is a lot shorter in hot countries.  You may well find that these cameras have sat around for years in which case the film will have degraded.  If you can, get something (nearly) in date!
  • Try to remember that the ideal distance from your subject is 1m to 3m, because this is how the lens is normally set.  Trying extreme close-ups is a waste of time!
  • It’s more about the effect than image quality…

So what photos can you get?  – Well, I’m not going to lie, it’s hit and miss. Here are a few examples that (with a little care) have worked out quite well:

Fish in Thailand
Fish in Thailand – Thailand is one of the easiest place to go fish spotting, as they’re literally everywhere, and near the surface where the light is good.
Snorkelling...
These cameras are great for the snap shots of family and friends that simply aren’t possible without waterproofing.
A blue fish in Thailand
If you dive down deeper, you can still get some decent shots down a few metres, so long as there’s still some light. Close-ups are a lost cause, though.

I think we can all agree – the image quality here isn’t great, but it’s great for a personal memory.  However, these have all had their brightness, contrast and most importantly their white balance adjusted.

Disposable cameras in the sea will all have a blue colour cast which needs to be corrected or it can make a photo really disappointing.  This can be done in several free or inexpensive software programs (such as GIMP or PhotoScape) – but only if you have a digital copy of the image.

Underwater digital photos on a tight budget?

So – let’s look at options when you have had a bit of time to plan.  Just how cheaply can you take photos underwater?

Aqua bag - a cheap underwater sealed bag (with a £7 second hand camera)
Aqua bag – a cheap underwater sealed bag (with a £7 second hand camera)

Just about the cheapest way, is to use an underwater camera bag.  There are loads on Ebay and Amazon – and here is one I bought earlier this year for about £3 (including P&P).

I don’t know about you, but I would be very dubious of sticking an expensive camera in one of these and just diving into the sea.  The problem is, there’s not really a good way to test them without putting something electric in them and going for a long swim…  (If it doesn’t work, I accept no responsibility…)

Because I was worried, I bought a cheap second hand camera for £7.  It’s 7.2 MP and has since become a firm favourite.  I’ve dived with it several times and it still works!  At £10 in total this is cheaper than a disposable camera. BUT – the results can be disappointing.

The key problems are:

  • The plastic “pouch” over the lens is not flat or perfectly clear, which plays havoc with the cameras auto-focus.  Since manual focus is impossible with most cheap cameras, this is a real issue.
  • Using the cameras controls / buttons can be very difficult.
  • The bag is not well insulated, so your camera will get cold quickly, spoiling battery life.

You can get fairly good results by ensuring that the camera lens is right up against the plastic lens window.  Alternatively, you can buy a more expensive bag with a solid plastic, or better, glass, window – which if right against the lens will solve many of these problems.  The issues with battery life and accessing controls will remain the same, though.

However, if you upgrade to a bag with a proper solid glass (or good quality rigid plastic) lens window, focus and image quality get a lot better!!

A “proper” waterproof compact camera

Of course, there are a whole range of custom-designed waterproof cameras out there, and after years of being prohibitively expensive, costs of some have now come down to below £100 in many cases (though well known brands are still more expensive).  In truth, these cameras don’t tend to stand up well against similarly priced regular (i.e. not waterproof) cameras on dry land.  Image quality and optical zoom both tend to be limited. But in the water they are generally much better than other cheap options.

Again, you will want to make sure that you know how to edit your photos once taken.  A lack of light and poor white balance are classic trouble-makers with these cheap cameras, though you would be amazed the level of detail you retrieve…

A key point about dedicated underwater cameras is that they have autofocus mechanisms that will work, and a quirk of underwater photography is that water is magnifying (so you can get better close-up shots).

If you get close enough... then a dedicated underwater camera is likely to expose and focus better (even if it's a cheap model).
If you get close enough… then a dedicated underwater camera is likely to expose and focus better (even if it’s a cheap model).

As a final thought (though not strictly underwater) – if you have a waterproof camera with you and quick reflexes, you may one day get a picture like this.

Making the most of what you’ve got…

As winter sets in, I find that the opportunities to take photos get harder and harder to find.  The hours of daylight are shorter, and tend to be while I’m at work – and the weather conditions and lighting all get worse.  As I find it impractical to carry bulky camera equipment with me everywhere, instead, I try to carry a small compact camera with me. I can then grab a few minutes taking photos if I find a nice scene or conditions are good.

At the same time, I also like setting myself little challenges, to see how far I can push the equipment I’m using, trying to get the best from the situation with simple gear.

Recently, I came out of work and I was walking near St Paul’s cathedral in London. I spotted an opportunity to shoot the cathedral (a very over-photographed building) through an archway, to form a nice “frame within a frame”.  The camera I had on me was my ten year old Casio Exilim EX-Z120, which I recently bought second hand for £6.

A second hand camera bought for £6.

The camera itself is nothing special (though I am rather fond of it, because it has a view finder, which comes in handy on bright days, and takes pretty decent “snaps” for most casual purposes).  It is pretty limited, though, in terms of its metering capabilities, low light response and dynamic range.  It’s therefore a challenge to coax the best out of it that you can.  Here is the final shot, which I will then give a bit of background to:

St Paul's from 25 Cannon Street

Overall, I am quite pleased with the result, but to get the photo to this state required a fair amount of post-processing (digital manipulation).

The shot, as taken, looked like this:

St Paul's unedited

You can see from the image, that the camera was not able to expose well for the darker sections of the image and the sky at the same time, lacking the dynamic range to do so.  The image also struggles because the parallel lines of the arch converge.  This could not be avoided in-camera, because it was not possible to stand any further back (my back was against the wall). I had to look up to frame the image.  Sure, it would be possible, with an expensive tilt-shift lens on a DSLR, but that would have been very impractical – so you have to rely on software, such as Photoshop elements to correct the so-called “barrel distortion” in the final image.

Similarly, the original needed quite a lot of levels adjustment to bring up the dark shadows of the early evening, and lastly it needed the sky restoring to it’ blue glory.  The sky was shot at the same time, in the same place, but correctly exposed for the sky only.  With multiple exposures, it would be possible to achieve the same or a similar effect using HDR compositing.  In my case, I simply cropped a square of sky and dropped it into the original image as a new layer and used the “darken” tool in Photoshop elements.  While some may view this kind of manipulation as cheating – all I was doing was restoring what I could see with my own eyes, but the camera was not capable of capturing directly.

Ultimately, you have to make the most of what you’ve got!

Great shots of cities at night? You need to learn to let go!

If you’re anything like me, you’ve probably been on holiday to some amazing places, but come back disappointed that you didn’t get enough (or any) good photos.  This might be because you were too busy having a good time, in which case great, but it might also be because you didn’t feel you had the right kit, you didn’t want to carry around a tripod or you didn’t feel you had time to make the effort.  But it needn’t be so!

For today, I’m going to focus on night time shots, because I think this is often when cities look best.  The blanket of nightfall can cover a multitude of sins… Dull grey skies, litter and unsightly graffiti. All sky scrapers look better when all you can see is their glistening lights.  In general, though, I think that a little bit of thought can help with your photographs at any time of day.

Again – let’s break it down to some simple “rules”.  The camera you use is pretty irrelevant here – an expensive DSLR, a bridge camera or compact can all take pretty nice shots.  For a couple of reasons that will become clear, though, mobile phones can struggle in this area.

“The blanket of nightfall can cover a multitude of sins… Dull grey skies, litter and unsightly graffiti.  All sky scrapers look better when all you can see is their glistening lights.”

Rule 1: Learn to let go!

Shooting shots at night means slow shutter speeds if you’re going to get a reasonable looking shot.  Shooting handheld is a lost cause (you are never as still as you think you are).  Find something to put your camera on and let go of it completely.  This will normally mean not even pressing the shutter button yourself – try using your cameras self timer (just a 2 or 3 second delay is fine) so that you don’t nudge the camera when taking the shot.  You don’t need to walk away from your camera and leave it unattended in a strange city, just make sure you’re not touching it!  (One of the problems with trying this with mobile phones is that they’re now so thin, they tend to fall over!)

Rule 2: Turn your ISO down and turn your flash off!

Okay, so rule 2 will only work if you’re already following Rule 1 (or if you’re using a tripod).  Otherwise you’ll end up with some really blurry photos! But as a general rule, flash will not be helpful when shooting night time urban landscapes, where everything is too far away to be usefully lit.  Instead, manually set your ISO low (if your camera allows you to do so) to keep image noise to a minimum and let the exposure be nice and long.  Some simple point-and-shoot cameras don’t allow these to be manually adjusted, but generally if you select flash off and night mode, it will do the rest for you quite successfully.

Rule 3 – Head for the high ground!

This isn’t really a rule, but I think a good piece of advice (particularly for high rise cities).  I would summarise it like this – Everything looks better from above (except for the stuff that doesn’t).  In New York, head to the top of the Rockefeller or Empire State buildings, (actually do both – Empire State at night, and Rockefeller in the day).  In Tokyo, there are lots of choices, but the Tokyo Tower seems an obvious choice.  In London, head to the top of the shard…

Tokyo

London
London – from the top of the shard (shot with a Canon EOS 1000D)

All of these were shot without a tripod, but a few words of warning regarding the Shard.  Firstly, it is really expensive to go up.  Secondly, they won’t allow you to take a tripod, even if you want to!  Which leads to the third point, there are no flat surfaces in the Shard. My earlier advice was to find something to rest your camera on, that simply won’t work at the top of this building.  Therefore, you either need to get very good at bracing yourself against the wall, or take a bean bag and balance your camera carefully, or sneak in some kind of miniature clamp-on or flexible tripod.  Lastly, the shard is in glass all the way around and it’s very difficult to deal with the reflections.  Get as close to the glass as possible and be prepared to remove reflections by selectively adjusting the levels using software later.

Mobile Macro Madness (Part 2)

I thought it might be worth returning to macro again immediately, having started touching on the subject yesterday.

When writing yesterday, I was feeling a little bit guilty about focusing so narrowly (if you’ll excuse my pun) on diopter lenses which generally only work with more expensive cameras such as SLRs / DSLRs / CSCs or bridge cameras.  I thought, since this is a budget blog, I should return to the more accessible end of the market, using a mobile phone or cheap compact.  In both cases, many have macro modes which allow you to get surprisingly close to small subjects.

“I was feeling a little bit guilty about focusing so narrowly (if you’ll excuse my pun) on diopter lenses which generally only work with more expensive cameras”

Here comes the science bit…  I have included this under the title “Macro” because it is generally used to refer to close-up photography. Strictly speaking, though, the term macro isn’t right for most mobile phones or compact cameras, but it is the technical difference which gives these cameras some interesting properties.

Macro: A technical definition. – The ratio of the subject’s size on the film or sensor plane to its actual size is known as the reproduction ratio – macro normally describes reproduction ratios greater than 1:1.

So – now we’ve got this out of the way, why are mobile phones not macro? And what difference does it make?

Well, if you’re old enough to really remember 35mm film, you’ll know it was called this because each shot was taken on a 35mm wide piece of film. This is the same size as the sensor in expensive DSLRs.  So, for a photo of a 20mm long insect to fill roughly two thirds of a photo, you would have needed a 1:1 (macro) reproduction.

Your mobile phone, though, will have a sensor which is considerably smaller, typically 1/3 inch, which is just 8.5mm across.  This changes the reproduction ration from roughly 1:1 to 4:1.  Don’t worry too much about the numbers themselves, but the point is that the insect you’re trying to shoot is now larger than the sensor you’re shooting it with, rather than the other way around.

Now, this reproduction ratio doesn’t mean you will actually be able to focus on something at very close distances (so you may struggle to shoot an insect which fills your whole frame, without some sort of adapter), but it will drastically increase the depth of field which can be achieved at the shortest distances your phone can focus at.

Here is an example, shot using my mobile phone, where you can see that nearly all of the flowers in the photo are in fairly sharp focus:

Honey Bee
A honey bee, shot with a Nokia Lumia 800.

This increased depth of field is, in my opinion, generally a bad thing in macro photography, where you often want to remove distracting backgrounds with a tasteful blur.  However, it does have some interesting applications, and you can have a lot of fun with them.

One of the great things about using a mobile phone is that you can often achieve greater depth of field from close-up of objects that otherwise would be impossible to keep in sharp focus when shooting at a short distance.  This might be useful when shooting models, dolls houses, chess boards, or other miniature environments or landscapes.  This can create some great fun opportunities to create some fun composite images.  (See my articles on software such as PhotoScape or GIMP for some free applications to do this).
