The photos of the kids on "white" look very good too. Well done and lots of nice expressive and cute images for a good start. I say this, and I don't usually "like" the common "kids on white background" look so often seen. Yours have enough color and variety (even with so few) to be visually interesting. (so this is a big compliment from me). In fact, if I were not a photographer, I would hire you (or take my kids to you) based solely on the best images I saw on your site. (another compliment).
However, when I clicked on the "Seniors" section, the "look" changed completely. It did not seem to "match" and looked like it was done by a completely different photographer (in a different style and "look").
So my Simple Suggestion: drop the old style senior photos and put up some that have the "new style" (yes...white) look that seems to be the "look" for the studio.
Another point...there was no pricing info and very little or no information about the photographers (you). Consider adding to the "About" section.
Ok, so i am definitely more in a position to comment on web design than photography. Your web design is nice. I was baffled by the 4 options on your splash page, why 4 options? Why are the 3 options other than "Visit Our New Site" (Should be entitled 'Enter Site'.) not options on the main site? Is there a difference between Rob Sigler Photography and Click Photo Studios? From a consumer point of view why are they A Linked together if there is a major difference, or B linked separately on your splash page if there is no major difference.
Main site:
Galleries: The order is wrong. It should be Babies > Children > Seniors.
I loooove the fact that the lower background colour changes everytime the photo does, very effective.
I must disagree with Steady, i dont think that the fact that your senior photos are of a slightly different style harms the site. They seem more mature, and less "Childish", take that as you will. You have managed to keep the display style the same which is more important in web design.
Up and Down Arrows in Info. Is there anything to go Up and Down too? Doesnt seem to be, get rid of the arrows.
Contact: "Your Message" should be a larger box to encourage writing.
Sharp looking site. I concur wholeheartedly with Steady Hand's inputs (after being shamed as a lurker...). The high-key lead-in Senior portrait on the gallery page threw me off... I saw it and thought you'd heeded the above advice and switched to the white senior portraits... only to find that that wasn't even one of the portraits highlighted in the gallery. Additional info about yourself and photogs would be nice as well... "Award winning" leaves me thinking -- "What award" answer that in a bio page...
Definitely need to work on my high key shots after seeing these (though I've just got the plain-ol' paper background vs. the plexi).
