No, I invented it!
Photographers have their noses up against the back of their cameras all the time. Why smell nothing when you can smell a nice fragrance? Once word gets out I think in 12 months first thing a photographer will put in their bag is a small bottle of baby powder! I'm so really proud of myself at this moment!
Ok, not totally the truth...some of it kinda is.
This is the multi function back off a Nikon F90X film SLR. Over time the rubber used on this back and the standard back that comes with the camera degrades and breaks down. This results in a very sticky back. You could put your nose against it but maybe not get it off! lol
My backs became sticky as well so I hit Google to see what other people were doing for a solution. I found guys were hacking at the rubber with razor blades, using alcohols, acetone etc. Then I come across a lady poster who comes in with something like, "I put baby powder on mine, works a treat."
She was right! I'm still playing around with this but the baby powder works! From the picture I posted I then wipe off the excess with a cloth. The back feels perfect, smooth as silk, no stickiness at all. The broken down rubber looks like it soaks in some of the powder and you do get left with a nice textured look as the white of the powder is still there. Not sure if long term I will need to re-apply but that's not hard to do. Works a treat and you don't need to destroy your back! AND, the part I said is the truth, I haven't used the camera since doing this but I'm sure I'll now have a nice fragrance too! All round success!
