FWIW, I use Profile Prism with my PRO-100 and Red River paper. IMO, the profiles I get are better than the Red River ones for the same printer. My scanner is an old Epson 4490 photo.

Don't feel bad. Most of my problems are self-inflicted. I've been using Profile Prism a lot more lately and find it's just as useful as ever.

I'd like to add that all this stuff is highly image dependent. My criteria is, "does it look natural?" That comment was made in the video about the grass and that's where the tone filter is great. It's easy for some things to take on a harsh or wax museum look if you go too far. If the images are very good to begin with, DFS (with no tone filter) numbers beyond about 2/100 give problems. I have images where 2/50 is about the limit before I start to see problems when pixel peeping. OTOH, on other images I go way beyond that, so there's really no general rule. Experiment!
4  Mike's Software / Qimage Ultimate / Windows 10 Nightlight Feature on: June 01, 2020, 11:34:05 AM
Just curious- would it be possible for Qimage to turn off the Windows nightlight feature, then turn it back on again when done? Depending on the adjustment, the nightlight can really mess up color balance if you don't realize it's on.

That's what I like about Qimage. Everything under-the-hood works right even if I don't always understand it!

Hmmm... Should I care about the difference, or is it not worth worrying about? What if my printer is great but my monitor is a POS?
7  Mike's Software / Qimage Ultimate / Out-of-gamut for monitors? on: May 22, 2020, 07:48:01 PM
Maybe a dumb question, but since we check for out-of-gamut for the printer, can the same thing be done for monitors? I'm pretty sure my PRO-100 covers a wider range than my sRGB monitor, at least in some directions.

Clever feature, seems to work well. I also noticed the warning if I try to examine before a rebuild is complete. Thanks!

Glad to see some activity here. I've taken a few photos but am being pretty strict about not leaving the house and not leaving without wearing a mask. Many of us are in the age groups that don't do well if we get this virus.

If I could get a clear night I'd like to try a moon shot on the telescope with the Z6. There's also comet Atlas, but it might be better to wait until it brightens up a bit. Terrestrial stuff isn't too exciting right now as we're in mud and crud season, though I did take a shot of the woodchuck in the backyard a couple days ago through a fogged thermopane window. "Well, that worked out about as well as could be expected."

Stay healthy,

Ha! Same cheat I use with the spot-the-difference photos. I just wondered if I could get the benefits of Qimage to refine, edit and crop two photos, then get them placed to print on a single card. I suspect the needed positional fiddling is best done elsewhere, but figured it never hurts to ask.
11  Mike's Software / Qimage Ultimate / Stereo cards on: March 13, 2020, 12:01:31 AM
I know there  are various groups and dedicated software for this, but recently had an interest and wondered if there were any tricks to using Qimage to do them. Read the very old thread here- http://ddisoftware.com/tech/qimage-ultimate/cross-view-3d-(stereo)-can-you-see-this/

I have a variety of cards that are 3.5" x 7" with images of about 3" x 3 1/4". Some are of low quality and halftone printed, some are actual photos mounted to the cards. I'm guessing my PRO-100 could easily best the printed ones, though this is really pixel peeping at its finest if you use a magnifying viewer.

Anybody else here interested in this stuff?

BTW, I can view them easily using the relaxed method, but can't see how anybody would put up with the strain of cross-eye viewing. I've also got an antique viewer. I need to build a camera slider to do the best job of it.

Did a bit of shooting over the weekend of random outdoor stuff and was very pleased with the raw results from the above settings. Additional sharpening and adjustments were done with raw refine and the editor, as needed.
13  Mike's Software / Qimage Ultimate / Optimizing raw settings on: March 03, 2020, 06:24:18 PM
While trying to optimize my raw files I learned a few things (with some help from Mike) that might be useful. I recently got a new Nikon Z6, which can produce really good jpegs, and didn't think my raw files were even close in quality. I suspect the best raw settings will depend on many things, the subject matter, the antialiasing filter, the sensor and probably the lenses used, not to mention personal preference.

First, I use the image examiner to see what the effect of changes is. When you rebuild the thumbs, it takes a while before the progress indicator at the top of the screen finishes and you hear the second clicks. About 12 seconds for a single thumb in my case, but it may vary a lot, depending on settings and the speed of the machine. I mention this because if you start the image examiner before the rebuild is done, you won't see the final correct result. Took me a while to realize that.

Changing the raw settings doesn't clear any raw refinements or filters (I think), so it's best to delete those- right click on the thumb for the menu and do both.

My subject matter tends to be technical. Brushed aluminum, black anodized aluminum, text and plastics, usually without much color. Smart color works great on colored stuff (duh!) but can be detrimental on my sorts of subjects, leaving a slight mottle in the noise pattern. I sometimes have to print very large, so the quality of any visible noise is important. I also have editors who like to crop rather than asking for a closer shot.

My images are already quite sharp and only minimal sharpening is needed. More than that enhances noise and can look unnatural. Noise reduction is very personal and you just have to experiment. In general I prefer sharp edges and some noise, as opposed to a softer look. When I did film, I liked my grain sharp, so it makes sense, but you may have a very different opinion.

OK, so what did I end up with? DFS at 1 & 175. Put the slider below right under the 1 in 175. Noise reduction off. Special noise reduction off. Camera specific settings on. Smart exposure on. Auto fill on. Auto black level on. Smart color off. The rest as you prefer. Remember, you can turn on smart color in raw refine if needed. Ditto some noise reduction.

Those settings apply to my particular situation with the Z6. My main point is you have to experiment as the defaults may not be optimal for you. Hopefully what I've said is close to truth, but hopefully Mike and Fred will jump in and correct what isn't or maybe add to the knowledge base.

Old guy stories- Back in my darkroom days, black and white paper came in a plethora of surface finishes. Everything from sandpaper-like and canvas-like, to the well known glossy "F" surface that could be dried to a mirror-like finish on chrome plates. The maximum tonal range was always with the glossy finish because the blacks were blacker. Any other finish scatters light and the black isn't as black. If the paper used an off-white base, usually cream colored, that reduced tonal range even more. A canvas paper with a warm cream colored base was great for portraits and large prints, but a poor choice for most other things. My technical knowledge of color isn't as good, but no doubt saturation is affected the same way. Matte and many "fine art" papers won't produce the gamut range that a high gloss paper will. OTOH, it's horses for courses and you choose the paper for the effect you want, just being aware there are always trade-offs.  Cool

Don't forget the out-of-gamut check, which I find quite useful. Use your soft proof button at the bottom, then check the gmt box to highlight the out-of-gamut areas.
