Default Exif puzzle.

Sometimes I need to know the exif of a photo, but on my system it is a very hit and miss affair. I have Faststone image viewer, Photoscape, Fuji fine pix viewer, and Paint shop pro. I took two shots of a model car on the table top. they show up on all my programs, but one photo will not show any exif at all, the other shows some of my settings on all except paint shop pro. even photos I downloaded yesterday do not show any exif, I am totally confused and googling did no good, I am not losing any sleep over it, but would like to know how to display a decent list of my settings, Faststone shows the best list when I do find a photo that it works with. Any body clued up out there, Is it possibly a camera fault, or setting?

If you have taken the photo in jpeg format, and not done any editing, the exif should be readable with just about anything, including Windows (properties). When you edit and re-save, some programs will strip the exif, depending on how you do the saving. Using the 'save for web' feature, in most programs, will remove exif.
For viewing complete exif and other metadata, I use PhotoME, which is a free download. There is also a plugin available to allow it to be used within Firefox, from the right-click menu. (I think it works with IE too, but I haven't used that for some time).

Many graphics programs can display EXIF tags, but some of them don't
show all of the available tags. The Exif Viewer extension for Firefox displays a
useful list. If you want more, try something like ExifTool.

This is a typical list of tags from ExifTool:

Corkpix, that was a real eye opener but no thanks, all I require are the basic's apt, shutter sp, ISO, date, etc. Any more suggestions?

Seems like my problem is with paint shop pro, just did a check up and found the exif is there on any unedited pic's, the edited ones have no exif. I will try my editing in another programe and see what happens.

There is a program called exifer, which will allow you to back up and restore the exif on photos that get it stripped out after editing.
PSP should be able to retain and save the exif, IIRC. There may be a setup item or program option which can be changed.
