Hey all!

I'm relatively new here. I'm finally finishing up my camera trap build - it's been a long process. I'm using a Nikon 5200 secured inside a pelican case (with a pvc extension for the lens), three flashes, and a snapshot sniper (SSII) which is wirelessly synced to control my camera (and flashes).

I'm getting ready to set it up and try it out, and had a couple questions I hoped some of you could answer regarding changing light and temperature conditions...

Changing light:

First off, what are some settings that you guys like to shoot in? My first thought was Manual, but I’d hate to expose to a photo for late night time and have my subject come through at dusk, resulting in an over-exposed photo. Has anyone used the shutter-priority or aperture-priority setting?

What would be the best way to set up a camera trap for both day and night trapping?

Changing Temperature:

My other concern was actually condensation. While I was working on building my camera trap, I did a couple of overnight test runs and I sometimes had trouble with dew or condensation building up on the camera’s waterproof case I made. (Like I said it’s a pelican case with a PVC pipe extension out the front for the lens.) Sealed in front of the PVC I have a large clear protective lens filter. This is what would often have moisture build up on the outside face of it.

Does anyone have this problem, and is their anyway to avoid it? Again, I’d hate for a subject to trigger the camera, only to have the entire picture blurred because of dew/condensation on the outer filter.

I would appreciate any tips or suggestions. Thanks!

I don't use SLRs for camera traps so I can't help you with the settings. I use silica gel inside my builds in an attempt to control condensation, BUT ... Whenever there are fairly wide temperature variations (warm in the case and cool outside or cool in the case and warm outside) morning and evening or when a significant front comes through and it's humid there will be condensation on one side of the glass or the other. The silica gel may help somewhat with inside condensation but I don't think you can impact condensation on the outside (when the air inside the case is cool and the outside air is warm and humid). Some folks use an anti-fog (the type used for diving masks) but I don't know how well it works, if at all.

Oh, ok. Well thanks!
