Raw files

[pixiepixie1982]

Hi, hope this is in the right section. Brand new on here.
I'm in the first year of doing a btec level 3 in photography.

I have been doing high key & low key this last week and I'm having problems (for my assignment I can make no adjustments to my images). I'm using raw on a nikon d800e.

Firstly I put my low key pictures that were perfectly exposed on the computer and look at them. For a split second as it's loading it's fine, then they go under exposed (background not black, subject not blending),
Then I do my high key, they look fine on camera, look fine as a thumb nail, look fine for a split second , then they go over exposed!!!!

Could my camera make these changes thinking in over or under exposing. I did not think raw done this ??? This happens on viewing with picasa and cs2. Any help would be great, and please keep it in simple terms ;0).

Many thanks

Nic

It's merely the software you're using applying the in-camera settings to the image. It may take that split second for it to do so.

Keep in mind, the image you see on your camera's monitor is a JPEG with the applied settings, yet the monitor is a very poor method to judge exposure.

Thanks sparky, I'll just print a small copy for now and judge it that way. Normally it's no prob, but with a no tinkering allowed, makes it more crucial to understand (which is no bad thing) :0)

There is no such thing as shooting in raw and not making adjustments. You are adjusting the photo when you change it to jpg or some other useable file. If you are saying you can't post process the image then you need to consider shooting jpg with the in camera adjustments you wish to make. Raw is a digital negative with the idea of post processing to create the desired image. jpg is a digital Polaroid format.

What you are seeing when it loads is the small jpeg that is embedded in the raw file.
The computer shows that to you while it is loading the raw file.
It apples some standard processing which is discarded when the Raw file is open.

Thanks guys, that helps loads :0). I'll pass that onto my tutor (which I'm sure she will know this anyway) :0). Thanks again.

Just so I totally understand, was it lightening my dark pictures & darkening my light pictures because I could re adjust them if need be, I said this to my college friends and they thought I was been a little stupid :0/, want to make sure I have my facts right before I speak about it again. ;0)
Thanks everyone for your help
