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 click. Store your XCF in the same directory as the F-Spot images and add the tag “HasXCF” So you know that there is a XCF and can search for it.
Show 100 is coming up. What shall be in it? I know about the intro, but nothing more. Discuss it in the forum or in the comments.
