[Gimp-user] Large file size on TIFF to JPEG conversion

2009-05-30 Thread James Cobban
I scanned some microfilm yesterday. For some reason the software does not support JPEG so I scanned into TIFF format, putting 5 images in each TIFF file to reduce the number of times I had to enter a file name. When I got home I used GIMP to extract the individual images into JPEGs. Unexpectedl

[Gimp-user] Applying large blur only to selection

2009-05-30 Thread Leonard Evens
I want to blur the sky so that only pixels in the selection are used in computing the new values. Also, I need to use a large blur radius. I've done this in the past by starting off with a small blur raidus and progressively reducing the selection, increasing the (gaussian) blur radius as I did so
