*Hello from Sid and the Critique Club*
Welcome to DPC Michiel with a strong maiden entry that fulfils the challenge brief.
I like that you have converted it to mono and made good use of the tones available to you, I particularly like the sky with its lovely rich gradation though there do appear to be some problems in the lower left. I'm not sure if your commenter means this to be the banding problem but I don't see the sort of banding problems I would normally expect. This patch looks too abrupt and regular for that as though it is the remnants from some cloning or repair of some sort?
Given your exif it looks as though it was a very bright day which might explain why you've gone for such a small aperture, I would have thought you could probably have got everything as you wanted it with about f8, especially as you are using the wide angle end of your zoom. That's just an observation and makes no difference to your final image.
I do like the low viewpoint and composition, this is what gives your image its impact, well done. The shadows are a little dense, I would have liked to see just a bit of detail, I think the highlights are just about ok.
The one thing that mars the image is the lighting. If you had shot this at a different time of day when you had some oblique lighting on it, it would have really picked out all the lettering on the headstones and increased its appeal and impact enormously.
This is a very commendable start Michiel, we look forward to seeing lots more from you, Sid |
