Not sure what progtam yo are running with your camera or editing, but when I just click on properties on a thumbnail, say in my documents, it only gives me "general" data. With my pic inside of editing program, like Photoshop or PaintShopPro, do the same thing, and you will see an exif data tab...giving you exposure time, shutter spreed, aperture settings, and so forth

No, that isn't EXIF data.
The EXIF data is written by the camera (or by other software), and is inside the file itself. You can't see it in Windows Explorer (at least not under Windows 2000), but you can see it in some graphics programs.
A couple of free programs that will show you the EXIF data:
- IrfanView - go to Image/Information and hit the EXIF button
- Vallen JPegger - go to Image (or right-click on the picture or the filename) and choose EXIF Image Information
Different cameras/programs will include different things in the EXIF data - and different software will display the information differently. Here's a sample from one of my photos, in the format that IrfanView shows it. JPegger seems to show a lot more info than IrfanView, but most of it is gobbledygook (a technical term for "hexadecimal character values) - IrfanView shows a lot more useful information.

| I think Windows XP gives you access to the EXIF, but not Windows 2000. I use IrfanView myself -- free and works great. The version I use lets you export the EXIF to the clipboard so you can paste it into another program. |

I have another dumb question on exif.
Whenever I view mine, it always has created and modified reversed.
Is there some way to correct it? |

On an "original" they should be the same anyway. If it's not the original, we don't need the EXIF info. |

If you are using Photoshop Elements, open the "browse files" as each file is displayed the Metadata file will be in a window at the bottom of the screen under "file properties".
Using Photoshop CS2 Open Browse which opens Bridge and again displays the photo with a Metadata file folder on the bottom left side of the window.
Hope that helps.
Oh yeah, and the only "really dumb question" is the one you don't ask :-). I've had some of those haunt me for too long.

Ok thanks people
I have a further question I have downloaded infranview and looked at the exif data.
I am worried that I have inadvertantly altered exif data by namimg files or saving the wrong way. When i look at the exif data what should I be looking for? How can I tell its an original and how can I tell it been altered?
edit repeated words!

| Unfortunately, in this case the dumb answer is that we really can't comment on what to look for, or else it would provide a ready blueprint for people to cheat ... |

Renaming files shouldn't touch the EXIF data. But it's probably safest to assume that if you save it from within ANY program, then the EXIF will be altered. So if it's for a challenge (or even if it isn't!), keep a copy of the original unaltered file around.
I'm not saying that every program DOES update EXIF when you save - just saying that it's better to err on the side of caution and assume that it does, rather than assuming that it doesn't.

Yup. A lot of software does put it's mark on the EXIF. Some doesn't. Err on the safe side and don't open and re-save originals out of any software package.
It's easy to avoid doing this. Follow thest suggestions and you will have minimal chance of ever overwriting the only copy of your original:
- Always move files from card or camera using the operating system (e.g. drag & drop with Windows Explorer)
- Always make "working copies" of JPEG originals. Unlike RAW files, JPEG originals are sooo easy to overwrite and irrevocably change in the process. Put your originals in a folder meant specifically to archive them, then again use the drag & drop copy method to make "working copies" in another folder.
- For challenge entries, create a folder that contains a copy of the original (drag/drop again), your full-sized "intermediate edit, and the resized final submission. You could also add a writen record of your editing steps
- Back up everyting, often!
