Photo Pros Part 2

Cycling Photographers - Part 2
Even after getting your camera, lenses, memory cards and flash gun - then getting practice at using it for real-world situations - there is still plenty to learn. IMM_4396w
It is possible to get good results with Auto or Program mode - especially if you have an option for program shift to shorten the shutter speed at the expense of aperture size.

But it is best to take more control. You can either go for aperture priority (at say f4) and let the shutter speed vary or go for shutter priority (with a speed of say 1/500th) and let the aperture vary. You should also set the digital equivalent of film speed to 400 ISO or higher (subject to noise levels) to give you more chance of catching the action. With indoor tracks 1600 ISO is almost essential.

The next issue is getting clear in your mind just how the photos are going to be used. This impacts your camera settings. Straight sports photos can be shot as JPGs. Indeed Graham Watson has said that he only ever uses JPGs - and who can argue with the quality of his images. But even within JPGs you still need to choose between colour spaces - sRGB or AdobeRGB. The first is needed by photo labs / web sites and the second for the printed media. You can convert between these colour profiles later. But sRGB is a more limited profile than AdobeRGB. So if shot as sRGB then no extra image info can be added by conversion later.

Similarly any loss through JPG compression cannot be restored later. If you shot at JPG quality 5 you cannot decide to save with quality 10 later.

The other point about JPGs is that they are an 8-bit colour format. But Canon and Nikon DSLRs can provide 12-bits or, most recently, 14-bits of colour depth. This extra colour info is however only available if the images are saved in a RAW format - e.g. CR2 or Nef. Fortunately you can switch the camera between JPG and RAW very easily. So if you want the best possible quality for that magnificent scene in the mountains - the one with the riders in the distance against the snow capped peaks - then switch to RAW.

Not only does this provide the best available image quality but it means that you have much more scope for image adjustment later. This is especially useful when the auto (or even manual) exposure fails to get the desired result - since you have much more scope for correction. Once you are happy with the RAW image then you can produce a final image in 8-bit JPG format. However this will mean bigger images and fewer shots before filling the camera buffer and the memory card.

Next comes using that expensive flash gun - which with the 24-70mm 2.8 lens provides the best way of lighting a cyclist with their head down or with the sun behind them. But be aware of exactly how your flash gun operates. With Canon DSLRs and EX5xx flash guns, the default method of operation is to act as a fill-in slaved to the camera settings - i.e. the flash gun uses the camera aperture and shutter settings to control the flash output. This means that the flash gun does not lighten the entire scene nor mean that you can use a faster shutter speed / smaller aperture when in auto-exposure mode. To change this you will need to switch to manual exposure - and here you need a much more detailed guide to cover all the issues involved. But, on the good side, high-spec Nikon / Canon flash guns can synch to the camera at all shutter speeds when they are switched into high-speed (FP) mode. So don’t forget to set this for any action shooting.

The above quick summary relates to sports action photography. The requirements are different if you want to shot other subjects to a professional level. There are plenty of books on these subjects - but you can also get some free, authoritive information that I have found essential; see the boxes below.
