By popular demand, I've announced I'll be conducting some classes on space image processing. The first one will be Friday the 13th (oooo!) at 10:30 Pacific / 18:30 UTC. Come one come all!

I'd be really really happy for some of the experts here to contribute any tips and tricks you may have on dealing with any kind of image data -- raw JPEGs or PDS IMGs. I'm especially interested in any tricks some of you may have for wringing realistic-looking color out of raw images.

Also I'm going to explore using Hugin for panorama stitching; anybody here want to contribute any expertise on that?

Send me an email if you'd like to contribute in any way. Contributions can be as simple as sending me a few tips as notes in an email, up to a Powerpoint presentation with screen caps from your favorite software, and anything in between.

my only tip so far is " get used to using a hex editor and reading hex "
that is what i had to do to open the new moon topo .img


never used it but for the past 4 - 5 years i have used Nip2/ vips

to make panorama images

way , way ,way back i used to be a member of "The Planetary Society"


what type of help do you need ? right now gimp dose not support a 16 bit /layer image
BUT will open a png with the 16 bits spread over the red and green chan ( with the blue empty )

I use Cinepaint or nip2 for them .Cinepaint is easier to do this in .

For the use of Gimp and Hugin, I can give some advise if it's welcome Emily. For PDS img conversion to png, I used ImageJ, maybe you know it.

Thanks, Emily.

I'm so excited. I've cleaned out my trays, made a fresh batch of chemicals and put a new bulb in my enlarger. Can't wait to get started!

Huh, I've never seen that one before. Don't have time to check it out now but I'll have to investigate further.

Sadly, the same can be said of a great many other people! We'd like to have you back!


Blerg. I'll have to check out cinepaint too. Right now I'm just cheating for the class, opening 16-bit images in Photoshop and stretching them before playing in GIMP.

For PDS to PNG, you just can't beat IMG2PNG -- that's what I've been using. I have used ImageJ before, though. I'll probably be contacting you about Hugin! Thanks for your offer of help.

cinepaint used to be called " Film Gimp " it is a fork of the gimp version 1 ( well 1.8 with a specially wrote gtk 1.9 )

the user interface is for the most part just like gimp 1
but out of the box ( no addons ) will open 16 bit tiff ,16 bit fits and 32 bit tiff and fits and save a 16 bit red and green layer png . That gimp WILL be able to open .
and can handle MUCH larger images with the system resources than gimp can on the same computer .
an example - times are aprox and from memory
a 1.5 gig png in gimp ( open and that save ) about 20 min. cinepaint about 5 min.
