Wacky, inexplicable problem - DPChallenge Forums

Pentax DA 18-55mm f/3.5-5.6 AF

Just got me a new camera (hooray for me!)- now I'm trying to edit my first batch of images in the GIMP (2.2) - now for some reason...I sure as hell can't figure it out, every time I try to save an image with a quality rating of above .90 I get an error message saying 'bogus marker length' and the program refuses to save it.

Has anyone else had this problem - I don't have the problem with any of the photos from my old camera ??!!! This really is turning into the proverbial pain in the neck, so if anyone has had this problem or knows how to fix it let me know please!!

Cheers

Maybe Gimp 2.2 doesn't support your camera yet? You might try the forum there if they have one.

Good luck and congrats on the new camera.

What file format are they in? If JPEG, try opening them first with something else (like IrfanView -- free) and re-saving it in a lossless format (e.g. TIFF) and see if GIMP can open that.

Hmmm.... they are in JPEG format, GIMP opens them with no trouble, and it will even save them - so long as I lower the quality to .90 or below - that's why this problem is so bizarre. I might try that irfan view thing and see if that changes anything (I'm now assuming google will turn up this Irfanview thing).

Cheers

anyone else got any ideas/having the same problem ??

Why would you be saving anything in a high-quality, compressed form anyway? Shouldn't you be saving as a native GIMP format (analagous to .psd) or as a TIFF, uncompressed? The ONLY time I save compressed is for the web, and those are never that high a "quality rating" anyway...

I don't see why GIMP would "not support your camera yet", unless these are RAW files and GIMP can't read your cam's version of RAW, in which case IrfanView is the way to go for now (open RAW, save as TIFF), but neither of these should be offering a "quality" option. If you're pulling TIFF or JPEG files from your cam, support should not be an issue, those are universal.

Doesn't answer your question, though. I don't have a clue why GIMP is having trouble giving you max-quality .jpg saves, if that's what is happening. Never heard of such a thing...

Thanks guys!

Well yes.... GIMP is only giving me trouble on the full quality saves -and I've never heard of anything like that either...hence the title of this forum.

GeneralE - the Irfan view trick seems to have done the job - who knows why, but it has. So thanks for the tip. It's a minor inconvenience, but seems to work! It seems the DPC continues solve all (photography) evils.

Robert - I think you are right, I probably should start saving as TIFF as a habit anyway. I'll willingly confess I remain very much a newbie when it comes to the technical aspects of these photography shenanigans.

Anders,

Not "should", "MUST"... Whenever you save a jpg it loses something in the translation, and the loss is irretrievable. I found this out the hard way; when I started with digital I did dozens of stunning Cape Cod shots which I happily tweaked & pulled at every which way. They looked woinderful on the screen, but blow 'em up to print size and they look like crap. Weeks of work out the window, miles of hiking out the window, bummer.
