Color Settings Help Needed

So then, best practice for DPP?

Save to PSE.:p

Heh! Yeah, but ya know, I'm trying to help those who are getting started!

DPP does have a managed Print function, just not sure how well you can manage without just eyballing...

To all these statements that are in bold, I have to ask: But how do you know whether there are colors that fall outside the sRGB gamut, if the monitor can't show them???

Histogram, info palette.
If you use Lightroom: Guess.

And in response to the blue bold: If they do print, seems like it would be case of, "Well, it doesn't match my screen, but I like it." True?

On screen, out of (the monitors) gamut colors will clip, so some saturated colors won't show a fluent gradient where there is one.
Any in (the monitors) gamut colors will show okay.
So: use your eyes for the most part. For "extreme" colors: Check for clipping using the histogram and other tools.
If you want to check wether a transition is "good", softproof for monitor profile: The colors will be totally unreliable, but everything will be shown in the monitors gamut.

I don't accept the word "match".

Should have said "softproof" instead of "screen".
Apart from that: I get a pretty good "match" from softproof to screen. I'd use "resemble" for my laptop screen

All this discussion underscores what I always say about "knowing" your equipment. Besides using correct color management methods and properly calibrated/profiled devices, the more experience you have using XYZ monitor and printer, the better you'll be able to PREDICT the quality of the print output.

I think the concept of "predictable output" too often gets lost in these debates, replaced by "screen and print matching".

I am the OPoster. I have picked up a few points here ... and ... certainly I am not in the same skill category as most of you.

I saw the comments on "soft proofing" and aRGB - can someone lead me a direction that will help explain the use of that function?

Wow, this amazes me. It's like a pilot flying on instruments when the weather's so bad he can't see.

My second favorite response ever, after "yes-ish"!

I take it this means, instead of using a paper profile, I use the profile that my Spyder calibrator produced?

Yeah, we kinda hijacked your thread; sorry about that but there is a lot of good info here for you.
I learned all I know about softproofing by reading about it online. Here's one link http://thedigitaldog.c​om …fing%20in%20Pho​toshop.pdf and there are lots more. In a nutshell, when you softproof an image, it will show you approximately how it will look when you print it. Before making pre-print corrections, it will look pretty wretched, so you make changes (such as contrast and brightness) to get it closer to your screen image. So you end up with 2 files of the same photo: one for looking at on-screen and one for printing.

Go view > proof > monitor RGB.

Okay, thanks.

The color shifts that can be observed on the image preview when in DPP (Adjustment, Work color space) I toggle between, say, Wide Gamut and sRGB, make me think of the tonal compression that Perceptual rendering intent does.

Is it possible that DPP sends the image to the monitor trough a Perceptual conversion?

a.b. -
To test this idea I compared DPP's behavior when a monitor profile is set in Preferences to when sRGB is set. A conversion to a monitor profile could be Perceptual, depending on the quality of the calibration and the LUT(s) it builds, but the conversion to sRGB can only be Relative Colorimetric because it has no device based LUT. Sorry to say, I can't see any difference in the display change, no matter what is set in Preferences.

But you do see a change in the well-within-gamuts colors, don't you?

And Relative Colorimetric shouldn't be making any, right? Only clipping what needs to be clipped.

I guess it's done in DPP to better mimic the camera display (which isn't color managed).
IOW: It might be a "feature", not a bug.

But it's stupid all the same.

I just checked: the diffrences visible in in-gamut colors when switching between various working spaces, remain there when saved to the relative TIFFs.

Whatever the reason for that happening, at least you will get what you are seeing.

I'm not at my workstation with Photoshop at the time but can anyone do a quick comparison as to how DPP shifts in the rendering to how ACR does it?
