Re: Recent discovery -- maybe everyone else already knows this trick

For comparison, this is the result of using Raw Therapee's Chromaticity-by-Lightness curve to raise chromaticity near the high end, followed by its Lab-L curve to darken the high end. (Obviously, I worked on the Original Image and left the label. I had RT output an sRGB image.)

Re: Strange things happen to EXIF

Tests to get to the problem:
Look at the Exif data for the image in PWP.
Save a .tif from PWP and look at its Exif data.

Re: DxO PureRAW Released

The advertising page for the product and the photos there imply that the program applies the same tone curve and saturation settings as DxO PhotoLab. Even the latter's "no correction" preset seems to do stuff. If you like that style, great. If you want to start with less of it, Raw Therape...

Re: Open Canon CR2 files?

...extracting the embedded preview JPG from RAW as an option could be useful. Some (most?) viewer programs do that when they presume to "open" a raw file, FastStone, for example. Then save the image as a .jpg or .tif or whatever. (In the case of FastStone, see Settings | Raw for various o...

Re: Update Available - Version 8.0.171

I had never heard of DCP files so I looked them up. DCP apparently stands for Digital Cinema Package and is not a color profile... There are 17,576 (26^3) three-letter file extensions, but duplicates popped up long before. What Are DCP Profiles and Why Do I Need Them? Technically, each photosite in...

Re: Update Available - Version 8.0.171

From the white paper:

No explanation of .dcp camera profiles? For what it is worth, Adobe DNG Editor writes a profile in .dcp format, so it is something to deal with.

Re: A question about pdf

I believe in both Europe and the U.S. there are small shops that have a wide-format inkjet printer at the heart of their operation. Look for print shops that advertise "giclee"or "fine art prints" -- in various languages, of course. Some of the shops may state on their website th...

Re: A question about pdf

Bayphoto.com and Americanframe.com among other firms will print large photos on inkjet printers. You submit a .jpg or .tif in Adobe RGB or sRGB.

You are right. My blunder.

Re: a question about HW

Wow, A0 is 210 by 297 inches. I guess Jonathan mentioned stitching because inkjet printers like 300 or 360 pixels per inch input. You can upsize an image from perhaps 180 ppi if expected viewers will not get close to the prints. Taking shots with good technique for the stitch, and testing the severa...
