Ok I am from Florida and am heading to snow next week. Is there anything I should prepare. I have read putting the cameras in plastic bags when done so it can adjust slowly to warmer temp.   I have a plastic sleeve cover also while shooting.. I have some rechargeable hand warmers I was thinking on putting in the pouch with the extra batteries and also keep them inside my coat.

I have taken my cameras on many trips to snowy places, especially cross country skiing in Arctic Finland.

The two key issues are: battery life is shortened, so keep spare batteries with you - in a warm pocket. Having said that I have never had to change battery whilst out in the field.

The second issue is fogging up. If you take the camera from a warm place to a cold place, or vice-versa you can find the lens fogging over, but giving it time to acclimatise usually gets over this - otherwise have a clean microfibre cloth to clear the front lens.

I have seen people using lens warmers etc, but I have never found them to be needed, even when out taking northern lights photos.

    • ISO 320 is the A7R5's second base ISO setting. You will find at ISO 320 you will get better results than even ISO 200. I normally take a set of shots at 1600, 3200 and 6400 ISO. I am taking 60 light frames and 10 dark frames. I don't do any adjustments to the files before stacking. I really need to get organised and do some bias frames now. Here is pretty much my first successful Milky Way shot from a few months ago. I was combatting a bit of ambient light and quite a lot of cloud but I'm pretty happy with this. It was shot using my Sigma 16-28 f2.8 which is better at astro than I had anticipated, at ISO 1600.

    • Thanks for the information. Since my original post, I did some "experiments" at different iso settings. Best results were obtained at iso 320, and then increasing the exposure by four stops in Lightroom. The biggest difference compared to using a higher iso was that there was detail in dark foreground areas, while at high iso the dark areas were blocked. This is consistent with articles I've read about ISO invariance.
    • I do a bit of astro photography and do a lot of research etc. on best settings to use. I have never heard of anyone using ISO bracketing! Typically, higher ISO settings such as 1600, 3200 or 6400 are used and multiple light and dark frames are stacked to reduce noise. If you are worried about noise in dark foreground areas then just use a seperate exposure for them then blend the exposures in post processing. By the way, I also have an A7R5.
