First of the RAW images I took over the weekend at Sherkin Island. Forgive the grain, this was shot at ISO 400 under difficult light and the gull was flying directly outside our hotel room!
So far I’ve imported a few photos into the GIMP using UFraw and to be honest I don’t think shooting in RAW made much difference. I’ll reserve final judgement until later when I’ve had more experience with converting.
I ran into the same trouble I had before with corrupted shots. Looks like one of my CF cards is fscked. I’ll write to 7dayshop where I bought the cards, whatever good that’ll do me.
Running fsck.vfat returned lots of errors about clusters. I formatted and I’m running a test for bad clusters now. It didn’t find anything but I’ll run some more tests over the next few days. Meanwhile, here’s some more info on compact flash break-downs to digest.
I copied about 900MB of data back and forth to the CF card without a hitch. It might be a camera problem? They’re Viking Interworks 1GB cards. Anyway, I found two places, here and here that have reasonably priced cards.
I’ve steered clear of RAW photography for some time. Maybe it’s the extra few steps required to get a finished product, or the very large file size, or just that “it’s not jpeg!”
I changed the quality mode on my 20D to RAW this afternoon and was shocked when it told me that I could only take 79 shots! *gulp*
I fired off a shot, of an old Honda parked in front of my car and as I was in a hurry, forgot to do any more.
Later on I went searching and found a number of sites:
Raw Digital Photo Decoding in Linux – Dave Coffin’s dcraw seems to be the basic library that everyone else builds their GUI tools on. He went to the trouble of decoding the various RAW formats in existance.
Nikon D70 under Linux – plenty to read here, including a section on noise removal and links to a few GIMP noise removal plugins I must try out!
RawPhoto – the author says it’s beta quality code, but it works. I haven’t tried it yet however.
UFRaw – you can install this in Debian with apt-get install gimp-ufraw. I tried it. It works, now I have to read the user-manual to figure out what all those controls mean!
I’d post an example RAW photo but the only one I have is nothing to write home about so you’ll just have to wait in line like everyone else!
GIMP menus are going to be reorganized! Finally, no more Script-Fu, or Python menus, only one “Filters” menu!
What I’d love to see in the GIMP is a “My filters” menu where I could drag and drop frequently used menu functions. I’d drop Levels, Curves, Rotate, Scale and Unsharp to that menu for starters!
Here’s a panoramic photo I assembled from 2 shots at the Corpus Christi Procession on Sunday. I created the photo with the help of Panoramic Stitch which I mentioned a few days ago. It did a very good job, especially when you consider the foreground. I can’t imagine what kind of manipulation I would have had to go through to get those lines to match up! Using this GIMP plugin was simple – select a few control points, it figures out how close the points are on each image and then you generate the stitch!
I did try to stitch a 3rd photo to the left of this one, but the distortion became too great and artefacts were very evident. I hope the author is encouraged to continue working on this project as he has come a long way already! PS. Pana is Cork slang for “St. Patrick’s Street”, the main street running through Cork City.
This filter is rather new (only announced last March) but some of the examples look good: before and after shots show a striking difference. Peter Heckert posted some instructions in this thread relating to usage so I may try it.
When you close newer versions of the GIMP, a small dialog appears showing thumbnails of unsaved images. In the development version you can drag and drop those thumbnails to a “XDS” compatible file manager to save them!
Unfortunately, neither Nautilus or Konqueror support that feature yet, but Rox-Filer does!
An email to the GIMP User List has a link to a Python layer style plugin. I haven’t tried it yet but an earlier plugin doesn’t work in GIMP 2.x anymore so I’ll try the “proof of concept” Python one. Stitch Panorama 0.9.2 was announced on the list too. Replies were all positive, and Owen posted manual and automatic examples. I have a vertical panorama of Marshall Fields’ department store to fix up. I may use this to help me!
Ever wonder why you can’t write to a transparent layer? It is possible, you only have to enable it.
Oh, and finally.. if you’re annoyed by the way GIMP uses (or not) windows, then the next revision has much better control.
