If you are working with large files, its far, far slower in Photoshop.

If you make high bit adjustments to produce desired color and tone in the scanner software OR afterwards in Photoshop, there’s zero difference here expect the time it takes to produce the desired appearance. The idea of ‘disabling’ tone and color adjustments, a questionable setting (how do you know its disabled and just not sliders set to zero, some fixed setting?) seems like a silly and not very productive workflow. Either the scanning software was not correctly configured to produce a desired appearance or someone wants to do a quick and dirty job (hopefully in high bit) and use Photoshop to ‘correct’ the inability to do this job at the scan stage. You are creating RGB data (rendering).Ī ‘raw’ scan in the context discussed here is IMHO a bogus marketing term defining data that is not ready for prime time. As Barry states, the bayer pattern (which is really RGBG), is not, you must render it using a converter, each is going to produce differing results and qualities from the same, raw source data.

Its nothing like rendering raw, non demosaiced data! A scanner is a trilinear device, producing true color. The idea that you can scan an image as a ‘raw’ and go back and edit it later is as old as the original scanner assuming you would do this in high bit in Photoshop (again a much slower process). Any decent scanner provided more than 8-bits per color control at the scan stage, even before Photoshop had such functionality.

I’ve been using Photoshop since 1.0.9, its high bit functionality has evolved over the early years. You could this with the scan software or after with Photoshop but the later was far slower and, depending on how far back you go into scan history, not always a high bit function. The idea is to use the hopefully quality scan software to match the original if asked, or improve it.

A prescan with a fixed set of adjustments means little to a good scan operator. Its possible that the term “a raw scan” (meaning the default prescan) was used. I’ve been scanning film for nearly two decades. I think that the term "raw scan" actually pre-dated a DSLR raw file.Where might I find that reference?
