Today I talk about the Eraser Tool, Alpha Channels and Layer Masks - in short: about transparency. Jim got me onto this topic with an email. Jim, consider this the answer. Norman sent me another mail about F-Spot and using RAW and  XCF files. Up to the inclusion of XCF files in the database and an option to get images out of UFRaw in XCF or TIFF, just copy the path of the JPEG with a right...

After reading all your comments to this post and tracing back the origin of the mail I found out that this upcoming device is not from China but Chile. It’s only two letters difference…. OK, it’s a fake - but you should have seen this at one glance. Which device for nerds is shown with a bearded guy and not with someone female and near 20? Thank you to the people who recogniz...

This is the second show about F-Spot - one week late because of sound problems. Edit: I have said something wrong in the video: The hotkey for opening the tag entry is “t”, not “Ctrl-t”. “Enter” validates the input and “Esc” closes the entry field. It’s about editing images and exporting them into image sharing sites or into folders. Even a ...

Today I explore the program F-Spot. It’s an image multi-tool - you can rate, tag and index your images, store or export them and even do some editing with it. You find the F-Spot homepage at f-spot.org. F-Spot is a program for Linux and the Gnome desktop environment. But there are more programs out there for other Linux flavours and operating systems. For some you can even pay money. I ho...

This week it’s geek time. I found in the German c’t magazine an image which can measure the amount of change to contrast caused by an image manipulation. Yes, an image can measure. I contacted the author, Ralph Altmann, and we cooperated in translating this file from Photoshop to GIMP. (Cooperation = he did most of the work. ) The sound of this episode is a bit off. I have a new hea...

This week I start with a short introduction into autostereoscopic images, see two posts below. Then I  cover the GEGL operation “c2g”, which converts acouloured image into a monochrome image with a lot of noise or other other effects. It’s a “try out” thing - up to now I have not found documentation. Perhaps one has to look into the source. Be warned - some pa...

A lot of people miss “film grain” in digital images. I show how to add it (the exmple on the left is a bit over the top…). You can extract the grain from a scanned analog image or make your own digital grain with the HSV noise filter. I found these links useful: Gimp Guru and Petteri’s Pontifications. The last one is a very rich ressource. The end of the video is quite ...

I am back with a short trip into the land of the non-square pixels. You can change the resolution and aspect ratio not only of the image but also of the individual pixels. And then I have a reminder about animated GIFs - a “commercial” from SCALE 7x. SCALE 7x, the premier Open Source Community conference in the southwestern United States, returns to the Westin LAX Hotel, site of the...

This show has a new encoding, so it may not be playable on every device. I wanted to test this thoroughly before rolling it out, but the old converter program has some problems. If you run into problems - it should be playable on any computer with the program VLC. After a short visit to the Schnoor in Bremen and a Christmas Equipment Shop that is open all year Max makes a winter theme wallpaper...
