This tutorial follows on from my first tutorial which is designed
to work with most graphic packages and aimed at the digital photographer
who is quite new to post processing images for publication on the
internet. For this tutorial I am assuming that you can use Photoshop
and get a half descent image from your digital camera but just in
case a few pointers
If you are going on a planned shoot, it is important toknow what
you are going to do with your images once you have taken them. If
you just intend to publish them on an aviation website then you
may only need to shoot in jpeg mode. If you are going to try and
sell your work to a commercial company or have it published in aviation
magazines they will want as high a quality image as possible then
you would be far better shooting in RAW. Even if you plan just shooting
for the internet you will find you have far more flexibility with
a RAW image as compared to a jpeg.
So you are out shooting - ISO 100, F8 to 10 - aiming for exactly
the correct exposure with your metering. Well there is a saying
in the new digital era - ‘shoot high’. This suggests
that you should aim to slightly overexpose your image. The main
reason for this is that the dark areas of your image will not be
as noisy as they would had you aimed for the correct exposure. Slightly
overexposing your image in RAW is not a problem, as you will not
lose the detail that would have occurred if shooting a jpeg. So
let’s take our slightly overexposed image into Photoshop now.
Open your image and, depending on the software you are using, your
RAW image will open. In my case I have taken an early morning shot
of a Monarch Boeing 767-300. Challenging? Well there is a very dark
background behind the aircraft and a camera’s metering system
(depending how you have it set) will try to get the exposure correct
for the whole frame. This can result in the white areas of the aircraft
being exposed correctly with the rest of the frame being underexposed.
What I attempted here was to slightly overexpose the aircraft, keeping
the background reasonably well exposed. This minimizes the amount
of noise created in the dark areas by your camera. So what do we
have?
