I have a photo's I took with my D70 Nikon that come in at 2000x3008 and 300dpi. When I open in photoshop I can see this information along with the camera settings when the picture was snapped.

1) Can Gimp provide the camera data that is stored in the jpeg?

Yes, filters -> generic -> exif browser

2) Why does Gimp show the resolution as 72x72 when it was originally 300?

72x72 is the screen resolution your are viewing the image in, not the image resolution.

I am concerned that if I work with my photo's in gimp that I"m going to end up with a lower res jpeg which will mess everything up...

ONLY, if you specifically change it. You are safe :^)

Thanks for the info, but I don't have filters / generic / exif browser menu.

Maybe this is an additional plug-in - I don't have this either.

Also, if gimp is going to show me the screen resolution which I already know instead of the true resolution of the image then how do I determine the true resolution? That seems some what worthless to show me the screen resolution when asking for image properties doesn't it?

Is the resulution really set in the image file (some formats support this) or just in the EXIF data? You could try to use another tool, maybe identify from imagemagick, to check this.

on image,
drop-down menu
filters -> generic -> exif browser

again,
on image,
drop-down menu
view -> info window
(or , unless you have changed it)

PLEASE, trim your quotes

ps: You didn't say which version of the gimp you are using. The current version 2.xx is what I have cited. Version 1.xx displays the screen resolution in the info window and I guess you would have to obtain a plugin for viewing exif data (availibility unknown).

pss: metacam is available (google search). I have ver 1.1. It displays exif data from graphic images (doesn't work on oly raw).

you can make the original read only and never save an altered image on top of this. screens only show a certain number of pixels. those resolution numbers, since i figured them out, make little sense and whenever printing an image that gimp or any other graphics rendering computer app has touched -- the machine does what it will and is not dependent at all on those little numbers.

just never save over the original and relax.

It's not ported for the Windows version of Gimp that I could find (with my humble google-fu). It would be nice to have though.

NOTE: this is for Gimp 2.xx and will probably *not* work in 1.xxx which I believe the OP has.

Item: The EXIF Browser plug-in is not distributed with GIMP. (It may be included in some packages, though.) It can be downloaded from the GIMP Plugin Registry, at

http://registry.gimp.org/plugin?id=4153

Item: A digital camera image does not really have a true "resolution". Assigning one of 300 dpi is simply arbitrary. A resolution only exists when an image is physically displayed, on a monitor or paper. The 300 dpi value is simply a recommendation of a resolution that will give a decent-looking result when used for printing the image.

Anyway, the main reason GIMP does not show you the resolution is because it is stored in the EXIF data, and GIMP does not currently read EXIF data, it simply passes it through unchanged.

An update:

Thanks to Michael Schumacher I have been able to add a Windows binary for the EXIF browser plug-in to the Registry: exif-browser-bin.zip from

http://registry.gimp.org/plugin?id=4153

To install, just unzip it and place the unzipped version in the "plugins" subdirectory of your personal GIMP directory. Michael says this should work with GIMP 2.0.x.

Hi!

1) Can Gimp provide the camera data that is stored in the jpeg?

Yes, filters -> generic -> exif browser

I think it would be better to place in a new tab of Image->Info Windows dialog. That would be more self-explanatory. And the plugin should be distributed with the standard gimp.

I think some plugins is are really usefull (and frequently searched), so I think it should be good to package with the standard gimp distribution. Or at least make a standard pluginset package.

Best regards, Khiraly

Using 2.0.3 (on XP Home), the filter now appears, but there is the message, "Exif Browser Message This image has no exit data attached."

Using the EXIF info in IrfanView does show information. So I'm not sure what it all means!

Just upgraded to the GIMP 2.0.4 (Windows) and the exif browser now works. Great stuff!

GIMP 2.0.3 had a glitch in the EXIF handling, this may be the problem: http://bugzilla.gnome.org/show_bug.cgi?id=148632
