"Partial Color Photography", aka PCP, aka "crap", is what happens when someone, usually a photoshop newbie (or pewb, as we in the photo industry call them), succumbs to a mental battle between good taste and fascination with technology. Good taste being what looks good and fascination with technology being a fascination the technology. Pretty straightforward.
Basically, PCP is a black and white image with certain elements colorized, ie. eyes, flower or flowers, a butterfly, a stick of butter, etc..... You think of it, and i can guarantee you that somebody has done it. "Well this doesn't seem like a big deal", you're thinking. WRONG. it is a big deal. Just because you can do something, doesn't mean you should do something. For example; writing on blogs. Just because technology allows the planet to blog, doesn't mean that the whole planet should blog. Myself included. Unfortunately, i do, and that's that.
Just real quick, i will be the first to admit that i've done it once. I succumbed to that battle and created a piece of art and said, "that looks good in black and white, except for the eyes. The eyes should be in color." Luckily, i've long since abandoned the old ways and found my inner taste.
Just because photoshop allows you to make a photo black and white except for certain elements, doesn't mean you should.
I look through online portfolio's of wedding photographs and time and time again, i see the same thing. PCP'd photos in the mix. LADIES and DUDES. It's not classy. Try concentrating on the actual photo at hand instead of the what you're going to do afterwards. You'll most likely create better work.
My problem is trying to convince everyone else that it is a bad idea. It's a never ending cycle. People see photographers doing this, thus they think that it looks good, which makes the photographer do it again. Someone (me) needs to stop this horrific cycle. When someone asks for that kind of photography, someone (me) needs to look at them and say, "yeah, i'm probably not going to do that. It's bad taste." I'm not saying i know exactly what is good taste, but i certainly can look at this stuff and say that it is not.
Some of you might have already been verbally assaulted by me, courtesy of this topic, but rest assure that I definitely held back for fear of losing friendships. I don't know why that would make you rest assuredly but hopefully it did. Anyway..... I apologize to anyone that i've offended. If you like that sort of thing, you should probably just trust me, and not like it. You'll thank me when the revolution begins.
