I am no expert when it comes to understanding the technical aspects of RAW, histograms and exposure but I have learnt a few things over the years and thought I would share here.
Beginners are often asked “Are you shooting in RAW?” the reason for this is we see a lot of shots where the image is overexposed often causing the white parts of the bird to be “Blown” or lacking detail. It is very easy especially with black and white birds to get the exposure wrong. If you shoot in jpg you are pretty much screwed. If you shoot in RAW you can often recover a lot of detail in post processing by adjusting the exposure, highlights and shadows. From my understanding RAW captures everything and allows you to change the white balance, exposure, colours etc.
I thought I would share an example of where I completely messed up the in camera exposure and I overexposed the image blowing the whites. I had been shooting a Splendid-fairy wren which does not have any white. I then moved locations and started to shoot a Red-capped Robin in brighter light. I took a series of shots and once the bird moved I checked the LCD and to my horror I had forgotten to move the EC from +1/3 to probably -2/3. This was the resulting photo.
