What’s “meaningful black”? It’s a concept out of the book “Welcome to Oz” from Vincent Versac. It’s for this other program, but I try to convert it to GIMP. It’s not so easy - so we have to write a script to do the tedious work.

Information about the Zone System is at Wikipedia and a lot of other sites. Chris Marquardt has made a simple version of it for digital cameras.

At the end of the video I do some ironing. I made some promotional images for our organic shop around the corner. The team had donned brand new aprons with all the creases from packing still in them. Awful! I show you a way to iron them out after the shot. BTW, this works too with wrinkles in the skin of a portrait model.

The “Old Ink Challenge is still open. Give it a try!

I also have some updates about the forum and ask for input with a new design for this web site. Daniel (DRB) is helping me a lot - and he has made a great interactive and collaborative storytelling site at StoryEverTelling.com . If you are into telling stories with a twist or reading them - check this out and help him to build this up.

This video has ben rendered in a different way. Is the problem still there that it calls itself a MP3 audio file? Is it playing everywhere?

I shot this image on my way to Cakovec from the airplane over the Chiemsee. That is a famous lake in Bavaria. We were already so high in the air that serious haze made the image flat. It’s the one at the bottom of the image in this post.

In this episode I show how to get rid of the haze by using the curves or levels tool. And of course I have a way using layers. A layer copy in burn mode takes a lot of the haze away. Further fine tuning involves a layer mask and an overlay layer copy.

EDIT: Mathias (http://mathias.lindner.de.vu/) pointed me to an error in the layers version. The last overlay layer didn’t work well. I used a copy of the base image - I should have used a copy of the visible image after all the burning. “Edit|Copy Visible” and then “Edit|Paste” and setting the floating layer to a new layer by “Layer|New Layer” would have done the job. This image here is done that way:

Now one could start to lighten the cloud shadow in the forrest and water a bit and correct or enhance the vignetting made by the camera….. But this is not bad, considering the image where I started.

I couldn’t record in Croatia, somehow we never got a recording with sound and video. If I am invited to another such event, I’ll buy a strong enough notebook and test the setup before the trip. But aside from this it was fun and I met a lot of interesting people, most of them connected with the Croatian Linux Group “HULK”.

I recommended Akkana Peck’s book “Beginning GIMP: From Novice to Professional”. It’s the best book about GIMP I have seen up to now. If you buy via Amazon.com, use the link on her site.

I was in Berlin for four days last week. And I only took a point and shoot digital camera with me. So this episode covers quick editing of holiday pictures, done in two minutes.

In this short time one can only do the basic stuff. And so I give you some easy recipes for getting more out of your snapshots. If you take this small amount of time, your images will get a lot better.

• Rotate them, so that they are level
• Adjust the perspective to get these falling lines out
• Find a good crop
• Adjust the contrast with the curves tool, applying an S-curve helps in most cases
• Double the layer and use a layer mask to apply your edits only to a part of the image. Get more light into a dark corner or dim down a bright spot
• Double the layer and use overlay or screen mode to change the overall contrast in an image. Use the opacity slider to adjust the strength of this effect. Try other modes, sometimes they work really good.

Don’t forget the challenge! Make a monochrome image and post it in our meetthegimp.org photogroup at 23 and be sure to use the tag “mtg-monochrome”. The challenge ends March 31 1600GMT and I’ll draw a winner by random choice.
