When I am confronted with photographic issues, I try to experiment my way through them.

This is my attempt to deal with gathering light before sunup. These images were shot with a very high ISO setting as I couldn't get enough light to expose the images the way I like to. I used ISO 6,400 instead of the usual 200 to 800 range. Not sure if I like them or not.

The D500 is suppose to be good in low-light, so I would like anyone who shoots this camera or other ones to let me know if these seem to be the quality I should expect from the D500. Taking in consideration that I wanted to get faster shutter speeds, and the light was quite a long time before sunrise.

I brought them into post and brought the color from the normal blue morning light to a more reasonable tone, passed the image through a bit of noise reduction, and here you have the results.

As usual, thanks for any helpful info.
Enjoy anyway.

...for a while I hope...been out of commission for a few days, first time in years I've had to have an injection two days in a row...it's been very hot here for a few days now and today we're expecting rain and maybe a thunder storm later...thought I'd sit out on the patio and couldn't resist getting the camera out for a few shots. Some Chive flowers, very small, about 20mm across, an Aggie on the way and a couple I don't know...
