Ugh, scanning negatives means they'e got to be flat on the 8x10" scanner table.
Scrabbling around with a negative that's twice as long as the scanner, all the while avoiding scratches and fingerprints makes excessive overlapping an impractical solution.
I currently "place" the scans onto Canvas Draw (a swiss army knife graphics program). I jockey the two scans into alignment, then export the results as a .jpg file.
The only gripe is that data gets lost with each transfer and file swap.
I'm hoping that Affinity Photo is truly "one stop shopping", just let me get two images onto one large 8x20" canvas so I can do the aligning...
I tried it last night, (copy & paste) but Affinity won't let me do fine control image placement on the canvas.
