Hi. NIce entry. This is more along the line that I was thinking about for the logo. If you have ever seen the Armani Exchange logo or Black and White stores. Very sophisticated, etc. This is close. I am not sure about the "o" in studio. close up it looks a bit odd. I am going to dwell on this one a bit. If you have more ideas based on my comments please submit. I checked your portfolio and like your work. Your look is closer to the "big agency" look I am seeking.
Thanks DS, Since you're probably going to get a lot of entries with lenses, apertures and cameras attached, I thought I'd try something a little different. The "O" was taking the aperture idea a bit further as more of a loose, multiple exposure symbol. That being said, I understand that you're looking more for a sleek, hi-end agency look which usually shies away from having an obvious "this is what we do" element for the sake of it.
Will come up with some variations based off your suggestions as well…
