I have run into a bizarre problem which seems to be independent of Photoshop version - cs6 ->cc2018. I use Kolors Autopano to merge numerous files into a combined Tiff file. Many are not square. I take these images into Photoshop select the central image with quick select and then fill the background with a fill layer.
The resulting Image is square on the screen. If I save or export it as a JPG it is completely filled but if I save it as a tif the tiff only shows the fill to the borders of the original image. if I loaad the tif tile it LOOKS OK in the Photoshop view. but windows explorer shows ragged edges. If I run the Tiff file through the zoomify converter the raged edges appear in the zoomified image . I think I must have something set wrong in Photoshop but what it could be I have no Idea. Does anyone else know what would cause this?
its haard to describe accurately. So I will try again: Say you have a long flower like a gladiola and want an extreme close up Image of it. So you take a series of images running up the stem and over the blossom. Running these files thru the file merger will give you a diagonal set of images across the canvas. This usually comes out as a TIFF file with one layer. I open this file in Photoshop use the quick select tool to cut out the image and add a background layer with the fill layer command. This appears to fill everything. If I save the file as a jpg its OK if I save the file as a psd/psb it ok but if I use a TIFF I get the ORIGINAL outline of the images back again.
Sorry to be so long winded but it is weird. Any one know what I am doing wrong? (I would post a small image but it won't let me)
You have enabled layer saving in the TIFF dialog, which of course won't make any sense to programs that don't support PS layer data.
