Firsly, there is not enough to go on to make a valid critique, we’d need the brief you had to go on. ‘If it was just, ‘do logo for photographer’, then part of your job is to learn to extract more from the client. What they want to say and who they want to say it too. You need to begin to tell her stor. Personally, I am not a fan of logos in isolation. They are fairly meaningless until used as part of a brand identity.
Secondly, when presenting to other designers, I think you should lose the mock-up part and just present the logos themselves. They are so small on the image tha to see them you have to blow them up until they pixelate.
Thirdly – and you are probably not going to like this – I am afraid they are all very predictable and cliché. I have been struggling to say anything positive about them. They are aren’t terrible (though there are technical issues with some of them) but they are all just a bit, well, predictable really. What do they say about the photographer and her work? What makes her different?
If this was all I had to go on, I think I’d roll my eyes a bit. My take from this would be something along the lines of, 'here we go, another self-taught wedding photographer with a penchant for over-filtered instagram-esque shots.’ Not something she would want, I’m sure, unless she is just another self-taught wedding photographer.
Over-used visual devices like camera lens and aperture mechanism are to be avoided at all costs. It’s is up there with advertising a decorator with a cartoon of a bloke holding a paint brush.
Not what you want to her, I’m sure, but I hope it helps.
