Post processing lost when transferring TIFF file
Just want to know what I am doing wrong, after going right through all processing steps (BG, star cal, LP removal and other adjustments) I then upload the image to onedrive so that I can edit the photo a little more in Lightroom on my iPad, but when i open up the image in Lightroom, the data has been horribly washed out and it seems to have removed all my processing.
I am Windows based so my experience may not be quite as yours but I now always save my images from APP as 16-bit TIFFs with sRGB profile then within Photoshop use Open As to open the image files via Adobe Camera RAW for final tweaking. I believe that Camera Raw can also be used to open files within Lightroom.
Hope this helps
