Entry #18 is not exactly what I'm looking for, but I do see some potential in it. If there is a way to implement a reel of film into the "dhp" symbol you have created and go for a black background with brighter lettering, that would be great to see.
#47 and #43 are fantastic! I love the colors, but could you try it in a copper color for me to compare? And maybe put some extra emphasis on the word "photography". Thanks so much for your entries.
