Image Triage / Ratings

I've been trying to figure out the easiest and most robust way of triaging the RAW files. Ideally, I'd like the ratings to be embedded in the file metadata (difficult to lose). I noticed that Canon DPP (and reportedly Lightroom and PS Bridge) write ratings (stars) to XMP:Rating field. Did it become ...

Re: Improved Bilateral Sharpen-like algorithm?

And here is an implementation example from the paper. They split the flower image into 3 detail-scale components, whose contrast where adjusted individually and recombined.

Improved Bilateral Sharpen-like algorithm?

Here is an academic paper, but with implementation too. The movie explains the practical use in photography at close to the end - I like the idea of reducing the whole implementation to 3 sliders...

Workflow with mask embeded - size and TIFF compression

I noticed that .wfl files that contain masks are quite big. I suspect that the reason is that masks are saved as uncompressed TIFFs. Is there a technical reason (such as speed) for not compressing masks embedded in workflow files? Most masks compress beautifully. While manually Zipping .wfl files wi...

Re: Compositing 48 with 24 bit

And the automatic 24 to 48 bit conversion fills the lower bits with zeros, not random bits, right?

Compositing 48 with 24 bit

Dan asked it in passing in another posting - this is interesting, at least theoretically: What happens when a 48bit image is composited with a 24bit one: the result is a 48bit image that looks like the overlay, but the colour precision is actually 24bit still not 48, right? What happens mathematical...

Re: Unable to Close Window

Try this app (a single Windows .exe, 6kb) instead of Task Manager to kill a process that stopped responding:

Re: Viewing the R, G, and B histograms on top of each other

Here is another wish - correlating histogram clipping/blocking with highlight/shadow clipped pixels map (in preview?), though I remember Jonathan saying that there are technical reasons for not implementing histograms on preview window? Switching between HSV and HSL would show me all I need: HSV-V h...

Layout Create Grid Preview - Top/Bottom Margins mixed up

In Layout/Create Grid/Preview, it seems that the visualization of Top and Bottom margins is reversed. The actual layout reads them properly.

Layout and ObjectDropshadow

There is an entry 'objectdropshadow' in Layout files. Is this feature operational?
