I've created a solid standalone icon which is the number 5 reversed to create the letter "R" and normal for 5 of course. the mark is memorable and I've tested it out as water mark on photos. I do photography as well and know how important a solid water mark is for identifying who you are.
standalone mark, we can adjust colours at anytime the hidden image is an arrow pointing downward...which make a great visual marker for any studio store front signage...pointing the way to your studio
This variation on the original concept is edgy with an urban chic feel without being too abstract. The rectangle mark does make an exceptional water mark as tested before posting to here....I've also taken into consideration signage either a single sheet of brushed almuminum with knockout lettering and LED back lit would be very impressive or a canvass banner style hung form rods attached to your studio store front
