Nikon D50: hides under the living room couch, available for quick family snaps.  It's the camera I started back with in photography, after a looong hiatus from film. Nikon D7000: Backup camera to ...

color space: I convert down from whatever working profile I'm using to edit, to sRGB.  And, I also make sure that sRGB profile is embedded in the JPEG so color-managed viewers can do a proper ...

For working with proofs, I've been using a MS Surface 3, and more recently a Lenovo Miix 510, and they both work just fine.  I wouldn't call it "getting by", its a regular part of my workflow, ...

Simply, this. In the software I use, 100% display magnification is where each image pixel is displayed by a single display pixel.  Just wanted to get my uderstanding of the definition out there.... ...

Funny, 8-bit TIFF is not a lot of use so I get why I think they didn't include it, but 16-bit TIFF could be a post-processing game-changer... Edit: well, any 16-bit RGB format...

If I understand what you're getting at, it was indeed what I could do with it.  With the D7000, I struggled to ETTR to get the shadows out of the noise floor and I was constantly denoising in ...

Sorry 'bout that; let's go back to your original post: Or is there no point as JPEG are 8 bit? I think your observation below illustrates that there is a point. I read that RAW can be edited in 16 ...

A lot of computer science is like this: Two guys on a train, one sitting by the aisle, one by the window.  Every once in a while, guy by the window looks up, scans around and utters a number, ...

Ah, okay, the 14-bit data ranges from 0-16383, but it's delivered to the software by the library in 16-bit containers, 0-65535.  It does have to be subsequently dealt with by the software in the ...

I'm wondering if you actually read my post.  The image data may be stored in the file compressed and/or encoded, but once read from the file it has to be put in a container that the computer ...

I wrote my own raw processor.  When I open a raw file, the libraw library I use delivers the image as an array of unsigned 16-bit integers.  If the image was compressed or otherwise encoded, the ...

If you look at a 256-step gray scale corresponding to the possible steps of an 8-bit image, the distinctions between successive steps are on the hairy edgy of visibility.  256 times more ...

IMHO noise reduction in post should really be a last resort, prior to doing these things where/when possible: 1. Getting the best exposure possible to keep dark places off the bottom of the sensor ...

I've found flowers to be good subjects.  My wife likes to have a grocery-store bouquet once in a while, and she also raise orchids, so the subjects abound in our house.  I've found the north light ...

Cool! If you do, here are build instructions for the light box: https://glenn.pulpitrock.net/Camera_Profiling_Spectrometer-Build_Instructions.pdf

I'm finding that the simple LUT camera profiles I've developed with this SSF data go a long way toward corralling colors to retain some notion of gradation.  But the real potential of SSF data is ...

Data Reduction, 3rd paragraph: -D in the dcraw command shouldn't be there; the TIFF needs the demosaiced image.  -h is best, doesn't modify the values.

Yes indeed.  Sorry it's taken multiple tries on  your part. So, it would seem a conversion to energy would be prudent, if the human eye responds to that...  ?  I haven't seen such a consideration ...
