Hi Mike.

Ive uploaded a mod, - one of a few Owls Ive done today, - but the first Barn Owl.

The basic image is underexposed, and its underexposed because you used -2 EC. Think about why you decided that. You were concerned the white of the owl would be overexposed, right? But think like a camera. The camera is seeing a lot of light coming in, with the centre a little brighter than the rest, so as its set to multi-segment, it will make a decision to even it all out, with some weight applied to the middle, which it will slightly underexpose, - or, perhaps expose correctly. You then tell it to underexpose whatever it sees by 2 full stops. Thats a LOT of light lost.

So step 1 is try the shot with no correction; check your histogram; and only then apply EC either + or -, and take the shot again. As a rule of thumb, if your subject is white and fills most of the frame, use positive, not negative EC.
So for a full frame white cat, use +1; and for a full frame black cat, use -1.

Then sharpening. Sharpening can only be successful when there are edges between pixels, where it works to increase contrast. In fact, contrast and sharpening are first cousins. And, to have edges, you need contrast, which is light from the side; and a lens capable of resolving fine line detail (high MTF scores)

In this shot, there are few edges, or detail on the breast. The only area that can be sharpened are the face, and the edge feathers. The Owl may have had some breeze flattening the chest. The use of a higher than needed ISO also contributes to lack of original sharpness, as noise is reduced by blurring. It seems that ISO 800 was the lowest you could go though, as using no EC would have moved the speed to 1/250.

Once exposure is corrected, you may notice that the white of the breast seems a little blue, - which is due to white balance, and white balance is affected by exposure.

The mod is also cropped to an 8 X 10 aspect ratio, with the Owl moved off centre. I can see some sharpening in V2, - very little, and I also had some difficulty with sharpening.


I hope this is helpful. If you have any questions, just ask.



regards

Nice shot Mike. I think V2 is a little sharper.
Recently been to Bridlington B o P centre and tried some owl shots myself.
Not as easy as one might think.
I found the advice from Willie above most interesting and will
try to take those comments on board for myself.

Mike.
