Flats question

[Lester]

Hi all,

I have just begun taking flat frames to reduce the vignetting in my images, and am pleased with the results.

If you alter the ISO setting to you have to reshoot your flats? I wouldn't think so, but could be wrong.

Thanks.:thumbsup:

Flats (and, associated flat darks) are shot at the lowest native ISO of your camera.

So, typically, ISO-100.
