TIFF files are causing error when uploading photos onto iCloud photo stream
I have been learning how to use iCloud and find it wonderful. All is working well except for the photo stream. I am unable to upload my photos that are in TIFF files. When I attempt to upload the TIFF files an error message pops up indicating that the only accepted files are the ones in JPG, TIFF or RAW format. Another suggestion it gives is that the file may be too large. The manual indicates that files in TIFF format with maximum 100 MB are acceptable. The ones that I was uploading are in TIFF format and are 35 MB. After analyzing the TIFF files I was uploading, I realized that some of the files in TIFF that were previously in NEF format were the cause of error while uploading the photos onto photo stream. My photos are taken using a D5000 and are mostly processed through a Nik software: Silver Efex Pro 2. TIFF files that were originally in JPG format are uploading well. I have come to understand there is a feature in conversion from NEF to TIFF that is non-recognizable by photo stream and that is the cause of my problem. I need your help.
