David, Thanks for your apt advice. I will practice night shots whenever I can get away from the city. Obviously, it won't be the Aurora, but at least I can practice getting the focus correct and experiment with different shutter speeds. Just practicing using the camera in the dark will be a plus. I will happily post any successes online at PN. Thanks again. Larry

Glenn, I really like your last post of the Milky Way. Can you share the exif data and the location? David, your first image with the red cliff and tree is quite good. I will be going to Alaska and will be on an Arctic Circle day trip to photograph the Northern Lights. I have been reading Patrick Endres' e-book, How to Photograph the Northern Lights. It's superb and he's most helpful. I purchased a 16mm f2.0 lens for the Aurora. Any other tips you can send my way? Thanks. Larry

You keep saying that you respond to my questions, but I either don't get your responses or you refer me to some thread I can't find. There doesn't seem to be a place to search threads.

I have been a PN subscriber for 10 years, although the new site only credits me with nine, I suggest you listen to the frustration of your membership with this clumsy and difficult to negotiate site. The old site was user friendly. It was easy to communicate with PN peers. This site seems to be all glitz and no practical functionality. I have waited a while to complain, giving the site a chance with no avail. I have asked a few times for help in how to create new gallery folders and never got a response. I requested feed back for my comments, but not feedback for each of my PN colleagues that I follow. You clutter up my inbox. This site appears to have been set up for the PN administration to sell images, not with adequate attention and respect for the needs of your subscribers who keep the site in business. For now, I am sticking with PN because I value the connections I have made and expand with other photographers. To me PN is a learning and sharing opportunity. Unless you take measures to make the site user friendly as it was before, you will lose many of us. I suggest you read and heed the other negative responses from subscribers also. I'd like to know what you are planning to do to make the site more usable. Thanks.

Bob and JDM, Thanks for your input. You confirm my sense. Getting the best exposure in camera using ISO normally seems best and then tweaking it in Camera RAW in post is my procedure. I think I will stick with it. Bob, I will look at Lee Varis' book. We always need to learn more. Thanks to you both. Larry

Net R Thanks for your response and for the attached link. It is good to know that the D7000 is ISO invariant. I don't agree that I can get usable results straight away from the camera's display because as I have noted above, the images would likely be too underexposed. I couldn't understand the numbers in the chart you attached. Thanks, again. Larry

Josvan, I agree that it is the quality of the image as captured that matters most. With this invariance ISO, the captured images in the camera are likely to be grossly underexposed. The original capture on the camera's screen, as I understand it. would not be too useful for measuring the image's quality because it will be way too dark. This is why I want to get real experience from others who have used this technique. Thanks for reading my post and for your response. Larry

I just read a couple of Internet blurbs about ISO invariance. What is your experience with this? Would or do you trust that adding exposure in post processing will result in images as good or better than those created using ISO at the appropriate setting for the light conditions for your images? I've included one article on ISO invariance for your perusal. I use a Nikon D7000. I'm more than a little skeptical about this. I appreciate your input.
