Hello everyone, This is a technical question about scanning but here does seem the best place to post it. Apologies if it should be somewhere else. I've read through Cazza's document on scanning and am wondering about bit depth setting as it isn't mentioned in the document. Here's my thoughts:
Setting 16 bit depth will double the file size, but increase colour accuracy.
Setting 8 bit depth will give smaller file sizes possibly allowing me to edge up the pixel density for an acceptable file size (acceptable file size would be something that I can edit, having multiple layers open at a time without running out of memory). I vary the resolution depending on the size of the photo and the size of the faces in it.
I can't see any difference between images scanned with 8 / 16 bit depth so I prioritise pixel resolution over colour accuracy as my computer scanner / monitor don't have any colour calibration and I've been using 8 bit depth. Most of the photos I'm scanning are black & white or colour but printed 30 or 40 years ago and the colour representation on them isn't good anyway so I don't believe I'm losing anything. I'm assuming that years down the line, when we have lots more computer memory, it'll be simple to convert 32bit images to 64bit.
Is my understanding correct? Should I carry on with my existing settings or is there something that I haven't considered?
