ISO issue on manual?

Hey, Im Charlotte, Im new to this site, just joined yesterday (heres the link to my intro)

Just wondering if anyone else has had the same ISO issues with this camera as I have been having with the D600...

Ive been noticing lately while using manual that my ISO numbers are way off. My camera seems to do just fine with automatic, but I hate automatic pictures.

In order to shoot in natural day light (indoors with incandescent lighting), I have my camera at 1/40 f2.8 ISO 5000, just to start to get a decent image - but still not useable. I first noticed this when I was taking pictures outdoors as I had to compensate with the ISO tremendously. I called a camera store that I usually shop at, and they told me to pull the battery and leave it out for about 30seconds. I have been doing this but its starting not to work.

I was going to send it into Nikon to have it repaired and then found out I have a grey market camera, so Im pretty much stuck right now. I checked Nikon to see if there were any firmware updates but my camera is UTD anyway. Ive also reset all of my interal menus multiple times as well.

Has anyone else had this issue before? Thanks for your help!

Welcome to the forum.

On the menu, go to ISO sensitivity, turn auto ISO on. Minimum sensitivity to ISO 100, max to ISO 6400 or whatever you prefer.

I agree, we need to look at a sample image with exif data. Also - do you have another DSLR handy to compare with??

I dont have a way to find the EXIF data. From what I read I need photoshop for this or something? I only have PS elements.
I dont have my 2nd dslr handy to compare pictures - Ill probably be able to get it in a few days (my dad uses it), then I can post both pics to compare!

To get the EXIF, right click on your photo. Select 'Properties' then 'Details.' It should list the ISO, f-stop, shutter speed, and any other appropriate information. :)

How will this help the fact that ISO is out of adjustment?

How do you know that your ISO is out of whack? It is possible that the lens that you are using have sticky blades but you didn't mention if it only happens with a particular lens or does it happen to all of your lenses? If this is common with all of your lenses there are other sites that can diagnose your camera.

Oh, I know how to do that! I thought you were talking about different info... I needed to find shutter clicks once and was told to use EXIF info but I had to find that on photoshop.

BUT anyway... my experiment is failing! I tried to compare pictures from my D5100 and D600 and when I read my EXIF data it does not match what my camera info is telling me. When I take a picture on the D600 at ISO 5000, my exif data is telling me 6400... When I take pictures with the D5100 the camera is set at ISO 1000, and my computer is telling me ISO 4500..:confused:

So uploading my sample pictures wont really help... but on the D5100 I need ISO 1000 compared to IS0 5000 with my D600... (According to the camera)

If you resize an image to below 1000px on the longest side, upload to your gallery here (below this box you reply in, click "My Photos" and from there you can upload (remember to place it in "Members Albums")) - then you and all of us, can see your exif data.

Edit, didn't see your last post.

You keep failing to mention enough data. There are 3 main variables:

1. Aperture
2. Shutter speed
3. ISO (Sensitivity)

You need to expose the exact same scene on both cameras using the same values for aperture and shutter speed.... and tell us what the ISO is.

Were you using the same lenses on both cameras?

At this point you need to get MUCH more scientific about this. Start eliminating variables and being careful with what you do and start writing down everything you are doing and the outcomes (make a spreadsheet if that helps)

This is what I have noticed also since the original post was on the D600 and now both d5100 and d600.

Take the camera out of auto ISO and manually set it yourself. If you have the camera set to auto ISO, it *might* look like the ISO is one number before shooting, but when actually taking the photo, the camera might meter the scene slightly differently changing the ISO at the last second. Take a few new test shots with the ISO set manually then see what is listed in the properties.

Sorry, I just assumed everyone would assume Ive been doing that...

Ive been using the same lens, same location, with a Nikkor 40mm at 1/40th of a second F2.8, ISO ends up being around 5000 on the D600, but only 1000 on the D5100. But Like I said, when I look at the EXIF data, it differs from what I have the camera set at.

I have been setting the ISO myself... Maybe I should also clarify that I have been shooting on Manual, not A, P or S or any AUTO setting.

This sure sounds like auto iso as @hark said. Setting the iso yourself does not convince me you are not in Auto ISO. When in Auto ISO, you can still go through the usual motions as if manually setting your ISO, but if auto iso is active you would actually just be changing the minimum iso for auto iso.

It can also make a huge difference if you are in matrux or spot metering when making your adjustments/light readings. If you are point at a black object lets say or white huge difference if spot metering.

What happens if you use other settings like A/P/S? Is it the same? Also what are you taking a photo of? Is it brightly lit? Have you tried using flash?
