Hello i am quiet new to PS. Today i made simple collage from 3 photos. I clicked new and set size to A1 format with 300 DPI and 8 bit colors. Then i used 3 high resolution photos to make a collage in A1 format. Each photo i used was JPEG and had around 3 MB. When i was done with it i tried to export it as a JPG. Its already been about 1 hour and it is still procesing the picture! Why does it take so long? what have i done wrong? Quality was set to 100% Image size when procesing is 8376x11859 px , Scale: 47% nad Resample: Bicubic....any help please?
