I am about to start working on prepping a couple of hundred files for a book project, and I will need to process the raw files from my 10D through my usual digital darkroom and sharpening workflow. In the end, I will be converting to CMYK.
I just finished re-reading the Sharpener manual, and had a couple of questions. I noticed that the Sharpener workforkflow for ACR is to make basic global adjustments and acquire the image in 16 bit at the camera's native resolution. Then apply the appropriate Capture sharpener, and output sharpener after upsampling or downsampling with Bicubic Smoother or Bicubic Sharper.
So my question: I had assumed it was better to upsample or downsample in ACR to take advantage of the better upsampling/downsampling capabilities. Is this not the case when working in the context of a sharpening workflow? I'm guessing that the sharpener routines are optimized for 'real' pixels as opposed to uprezzed/downrezzed ones. Is that the case? In most of my images I will need to downsize, but there are a few images that are running very big, or from which the designer cropped a lot and is using only a small part of the frame. Those I will need to uprez a good bit from the native rez, and I'm wondering if this is better done earlier in the workflow in ACR than with bicubic smoother after the fact.
I presume I want to run output Sharpener (and then flatten) immediately prior to converting to CMYK, yes?
Thanks for any input.
