Re: How to cool down
 

A little bit off topic, but one thing I've often found is that using any sort of viewfinder or loupe can be tricky if you're hot -- not only does your sheer body heat fog up the glass, but the sweat drips into your eyes. Maybe I've just got hot blood; I don't know. So even in colder weather I tend to dress light.

The safety net for any really hot wedding is that probably the groom is in a dark suit, and probably the bride is ensconced in heavy clothing, so they don't want to be outdoors in the blazing sun any more than you do, so they're amenable to doing the photoshoot indoors or at least in the shade.

Funny about the EVF fogging up..For me it seems to happen more often at the reception rather than outdoors in the sun ... maybe the humidity and all those hot writhing bodies on the dance floor are perfect conditions to fog up the glass?? I find I'm filming dancing and then everything goes misty in the viewfinder and I have to quickly wipe the glass whilst still trying to keep the camera steady.

To be honest I haven't really found a solution for it except use the LCD rather than the EVF!! I wonder if the old scuba trick about saliva on the glass and then washed off would help?( we used to spit in our face mask and then rinse it off in the water and it doesn't fog up at all) or some anti-mist spray?? I think GoPro brought out something that stops their cameras fogging up when in the waterproof housing.

That's a good thought. I think there are various types of anti-fog screens and wipes you can apply to help with this sort of issue. I've never properly looked into it though.

Sporting goods shops sell stuff you wipe on the inside of your ski goggles to prevent fogging. I tried it on my EVF and it works great.
