As far as I know, my work has a very strong claim of being unique; as far as I know from reading the literature and attending international meetings in my field, there is no one else capable of working with these organisms and producing these types of images from them. My images regularly elicit a very strong positive reaction from people.
"Unique"? Or "Unusual"?
Big difference...what you can technically accomplish, while perhaps impressive (and unique) in the field, may not translate directly to "sales" from a gallery perspective...
Don't confuse different with desirable. It's "desirable" that equates with valuable...different tends to run it's course (but make hay while the sun shines).
I remember seeing (and buying some prints) from a guy at an art show that did X-ray images of common things in an artful manner. I bought a print cause it was cool. Not long after, Adobe used X-ray tech to produce packaging for Creative Suite 2 (see this
article)
It was interesting and unusual but...it tended to die out.
Can you make a decent run at this stuff? Perhaps...but I don't think you need a "rep" (or agent) so much as a manager that can direct you and help build an awareness and position.
What you need to understand is in the grand scheme of things, the "common man" doesn't care about much beyond, hey, that's cool, I'll buy that. If you want to send the time cultivating the contacts and have the time to promote yourself, you might do ok. Selling "art" is a very difficult endeavor and jumping from one industry to another isn't easy.
I wish you good luck...but what you need is a body of work that is desirable completely separated from your main industry attachments. Outside of your peers, nobody really cares about the uniqueness of your imagery...only the desirability.
