Humid pool Shots

[Gibmeister]

I was asked by my YMCA to take some promotional shots of people in the indoor pool. My lens fogged up. Is there something you can put on the UV filter to keep the lens from fogging up? Any other good ideas on how to deal with this? Thanks

Remember it may not only be the outside fogging up but condensation can form inside also.
That said I would suggest taking the camera (inside of a zip lock bag) into the pool area and let the camera warm up to the surrounding temp. before removing it from the bag.
The condensation forms due to the cool lens contacting humid air sort of like a cold drink.

Ever notice a warm can of soda never has condensation.

I am not sure what camera you are working with but check the humidity in the pool area. My D60 has an operating range of up to 85% humidity. I have been in some pretty humid weather shooting and never had a problem but, it is something to keep in mind.

I don't think I would take shots in a humid pool area, the condensation inside the camera could turn your camera into an pretty expensive paper weight.

And from when you remove it from the bag until you remove it from the humid area, the air in the body will be gradually replaced with humid air. Every time the zoom lens extends or retracts it will pump air into and out of the body. When you leave the area and camera starts to cool down, that moisture will condense inside the body. It would probably be a good idea to open any ports in the body - memory card slot and download-port covers, e.g. - and pump the zoom lens a few times to expel as much humid air as possible before the camera cools very much. If it's an SLR, removing the lens for a few minutes will let air ciricualte inside - but with the obvious risk of dust entry, so choose carefully where you do it.

Thanks for the great advice. I put the Canon 10D in a plastice bag and kept it there until I was ready to shoot. Planed the shots, took the camera out of the bag, took the shots and then got out of the humidity. I then took the battery and the cf card out and then removed the lens. Hopefully, no negative effects to the camera. Next time I won't agree to do this type of shot. Thanks again.
