*Hello from Sid and the Critique club*
An appealing image that does not meet the challenge.
The rock is very appealing in its own right but in order to meet the challenge there should be nothing but rock, ie., no background at all. I can see your reasoning, the rock is certainly womb-like more than foetus like but this is the wrong challenge to use this in because you need to see the whole to understand your concept but to fulfil this challenge brief you need to crop significantly in order to fill the frame.
The lighting is uniform and illuminates the rock well and DOF is good though I wonder if you needed to use quite so small an aperture, perhaps f8 or f11 would have sufficed.
Sorry you didn't get any comments during the challenge, I hope this helps. Thanks for your submission, Sid |
