ISO changing on it's own

I'm not exactly sure how to describe this, but here goes.

I was making an attempt to take some moon pictures (nice full one tonight). It's also cold here so while inside, I set the camera up in Manual Mode, and made sure ISO was set to 100. I then took the camera outside and let it adjust to the cold.

I then waited until the moon was almost clear of the treeline, I started taking photos using my remote.

After the camera warmed up to inside temps again, I began loading the photos into Lightroom (2.6). All the photos appeared grainy and filled with noise. I checked the metadata and it lists ISO at 1600. I checked the camera again, and it still lists ISO at 100.

That is the problem I'm seeing. Can anyone offer an explanation as to what is happening?

Perhaps I should get on my knees and beg the wife for enough money to buy a new D7000?

To make it easier to answer your question, Mike, we'd need to know what camera you're using, lens used, etc etc. In other words, if you would fill out your profile, it helps us to help you. Thanks for joining Nikonites. I'm sure we'll be able to answer you as soon as we get some more information.

Although not stated I'll take a guess it might be a D60, anyway check and make sure auto ISO is set to off.

Ahhh Bill! Ya beat me to it! lol I was just thinking about that after I posted my other answer..about the Auto ISO being on in his menu. Not knowing what camera is being used, it would have been mere conjecture on my part. Hopefully he comes back with the needed information.

You could leave the iso on auto and tell your wife it's broken . . . might help with the new D7000! LOL

Don't tell the guys in Canada that you're in Virginia and shooting the moon from the INSIDE while your camera is OUTSIDE! LOL

First sign of imminent failure is uncontrollable high ISO erratic changes often accompanied by high noise photos, only a matter of time and it's a gonner...lol

LOL....Mike, don't listen to those guys. They're yankin' your chain. Seriously though, check your Menu to see if your ISO is on Auto, and turn it to OFF when shooting in Manual Mode, but only if YOU want to control the ISO. Doesn't matter what you set the ISO at when shooting in Manual. As soon as you press the shutter button half way down, the electronics in the camera take over and the ISO automatically compensates for the lack of light and adjusts it accordingly to get the best available shot. Hope you understand all this techy crap.

How can I possibly thank each of you properly.

Jack, the camera is a D60. I didn't think I needed to state that because I was posting in the D60 forum.

Bill, cut Jack some slack. I've seen some of the obscure questions that have been posted on here and he's trying.

I didn't even know about the Auto ISO setting, I'll look when I get home tonight. I always thought that while in manual, you set the number and it was done. I have so much to learn and not enough hours in the day.

Helene, I don't think that would work for me. My wife uses a point and shoot and thinks her photos are good (even with the grand kids fingerprints on the lens). I'll just continue working my extra hours each week until I can save up for the 7000 or whatever comes along to replace it. Maybe for next Christmas. I just wish I could have stayed inside but the moon was rising so quickly that I had to re-frame my shot every third picture. The D60 is also not very sensitive to the IR remote. You have to be within about 80 degrees to either side of the front of the camera to pick up the signal.

I may be in Virginia, but it still got down in the 20s last night and down to the teens tonight. I'm a warm weather person. Bring on Summer. That's when I'll experiment again with lunar shots.

Again, Thanks to all of you.

Mike

Mike, so glad we didn't scare you away! I understand the "warm weather" business. I tried doing time exposures from the inside of my truck by using the window as a "tripod" and with the engine running so I could stay warm. Not good.

I found out about the auto iso feature on this forum and when I turned it on, found it more of a nuisance than a help. So I make sure I leave it off on mine.

Best Regards

Helene, I've been married (to the same woman) for almost 39 years. There's not much that can scare me anymore.

I do have to add, that just reading the posts here by you, Bill, Jack, Jdeg and all the others have taught me more than anything I've been able to learn on my own... Thanks
