hi fiona welcome.this is a really nice image the girl gives the image a really strong focal. I am sure it would make a good black and white conversion also i messed around with image and cropped the rocks frm the top out and it worked well.
Nice shot, I would also crop the rocks from the top.
B&W might work alright, but If you are going to leave it in colour you might saturate it a little. Colours look a little bit flat for me. But I’m looking at it on a laptop screen.
This is a nice image with some strong lines and interesting feeling about it. I like the way the girl seems absorbed by the waves at her feet, enjoying the moment and the freshness of the water under the toes.
As for the crop, I have no real preference. My tendancy would be to keep the rocks in. The sand at the bottom and the rocks at the top frame this quite nicely.
Thanks for the feedback, I put the photo in b/w and actually prefer it ! Not too sure about cropping out the rocks though.
Photo was taken in Keem Bay in Achill.
