Canon Pro 100, color space advice needed

I guess I should clarify. Soft proofing is for checking out of gamut colors, etc. But if I'm going to print an image, after I have done all the other work, I will create a soft proof virtual copy and adjust it to what ever paper I'm going to use. Andthe neat thing about that virtual copy is that if I decide to use a different paper for a subsequent print I can change profiles in the virtual copy and adjust accordingly. That's the way I do it. I'm not saying it's right. But I like that approach.

There are lots of people who haven’t heard of soft proofing, there are those who have but still don’t use it. I will probably use it as a basis for adjustment in one image in a thousand; and I don’t think that is an exaggeration – I don’t have many cases of out-of-gamut colors in my images.

The problem with using soft proofing as a basis for adjusting for paper type is that soft proofing isn’t that accurate. You can have a screen that is 99% AdobeRGB (Lightroom’s default display space), an image in ProPhotoRGB, and a printer with inks somewhere between. When things are really tough, nothing beats a hard proof.

Lets face it many home printers haven’t a clue on the differences between relative colorimetric and perceptual rendering intents, let alone absolute colorimetric and saturation rendering.

There really isn't any point in discussing this anymore. I like my workflow and you like yours. Like I said, it works for me and I'll keep using it.

I can't imagine why you would think I am arguing against your or anyone else's worklflow. It is your workflow after all. Do you have a problem with someone having a different workflow?

No, it was late and I interpreted your response that you were arguing or trying to change my mind. It was unfair response on my part. This Pixma Pro-100 is my first and probably last venture into a "professional" level printer. I have never used profiles before. And I have just been experimenting with about everything I can think of. I "think" that I have my monitor adjusted fairly well, but I haven't invested in a hardware calibration device yet. My wife has retired, and I'm semi retired, planning on for retirement in June. So money is being watched more closely now. So, in my situation, using the paper/ink emulation in Lightroom is helping quite a bit. Either that, or print matching is easier than I thought. At least it has been easier than with my old HP printer that doesn't use profiles at all. I appreciate reading your responses Brian, and value your opinion.
 
This is only a suggestion, in regards to soft proofing. The Canon Pixma Pro 100 has a plug-in for both lightroom and Photoshop.

It is called Print Studio Pro.

If you use this add on with Lightroom/PS, you can do hard proofing for a given setup, I.E. an ICC profile and paper, then use the Print Studio Pro to print out a ring of various settings, which you then can

pick the best in your opinion. You can view the hard proofing in different light setting to choose which is best for you. May have to use a couple sheet of paper, but once done, you have your setup for future prints.

Jtoolman has a great video on You Tube showing how this plug in from cannon works with both Lightroom and PS. My thanks to him for doing this great video.

I just started using the Pro 100 and have had extremely good results after just two prints. Plus I am a newbie to ICC profiles/color gamut/..... down the line. I let Photoshop and Lightroom manage the printer with the Print Studio Pro plug in. Works great.

Enjoyed the thread

I don't know how he manages to be wrong so many times in such a short video. Incredible really.

Here is a reprint of my comment in Luminous Landscape:

If you look at the context of the video, I am explaining why people find that as soon as they switch their cameras to the AdobeRGB color space, their colors appear lifeless and dull. In the beginning of the video, one of the first things that I express is, "AdobeRGB is superior - IF you have the equipment that can exploit it". I then go on to explain that the majority of the wet process printers (RA-4) and web browsers are all within the narrow gamut of sRGB.

For those of you who do not know my background, I was a professional wedding photographer for 20 years, and shot over 1,000 weddings. I then went on to start a photo lab called, "Pictage, Inc." with one of the first Fuji Frontier printers. We were the first company to have to crack open the hood and tone down the saturation and up the midrange tones because the stock Frontiers were too hot. We literally had techs from FujiFilm in West Hollywood over at the lab every day to help me dial it in. Eventually, we got it all dialed in, and went on to become the largest online pro photo lab in the USA, going from six people to 170 employees before we sold it for $29 Million.

During this time, I was involved in testing and prototyping the Fuji S3 and S4. I shot the national ad campaigns before that. And prior to buying my Fuji Frontier, I spent time in Rochester with Kodak, aiding their engineers and testing the prototypes of what became Portra film. I then went and did a number of national platforms for Kodak, and Hasselblad, and appeared in Hasselblad's ad campaigns.

So I intimately know color management as we were the first on the horizon when the world switched to digital. The Fuji Frontier was the bridge technology, scanning negative film to digital (sRGB width) files, which then were stored and printed on RA-4 process printers. We had C-41 film developers, as well as our Frontiers, so I had to learn everything about color management. We had to bullseye our RA-4 output to adjust our chemistry to keep everything balanced. Back then, we used densitometers before the concept of Spiders was even a fantasy.

So when I do a video aimed at helping the enthusiast understand a very basic misunderstanding about color space, I used metaphors like "Muffin tops" and "wide rainbows" to help people understand color clipping - a very widely experienced phenomenon among people who read that AdobeRGB is better, switch to it, then are disappointed in their color. To help illustrate this, I showed a completely red and violet square, side by side, and used my apple monitor profile to simulate color clipping. By switching my printer monitor from sRGB to AdobeRGB, I forced the monitor to "expect" a wider gamut, thereby showing only the middle of the width.

So when Andrew Rodney went on the attack, accusing me of not knowing color management, and then going on to literally say on his Google+ page that my misunderstandings were possibly because I was having problems reading english (an obviously cheap and racist remark), I could not be ok with this. Not only is he being unfair and petulant, he is accusing me of a lot of wrongdoing. He accuses me of trying to mislead people for financial gain.

It is not of any benefit to me if people shoot sRGB or AdobeRGB. I do not sell educational products about color management like Mr. Rodney does. The reason I'm doing this is because I spend a lot of time internationally giving workshops and seminars simply to learn the needs of photographers, so I can stay in touch with what my customer's needs are, and to understand what hinders them from improving their photography.

Despite the cheap shots I've seen here about my "tupperware", my products are the market leader, are carefully researched and tested, have a ten year history of use worldwide acceptance. You'll see my products in use at press events, magazine shoots and by NASA. Jay Meisel, Greg Gorman and many other legendary photographers use my lighting accessories. My Lightsphere was named Popular Photography's Product of the Year in 2010. I have had the good fortune of, well, good fortune, so I don't need to make money off of misleading people for whatever motive in misleading them about color management.

I had a lengthy phone conversation with Will Crockett today, who originally was poked at the beginning of this thread. I have known of Will Crockett's deep knowledge of color printing because he was giving nationwide tours for FujiFilm back when I purchased my $240,000 Fuji Frontier. The management at Fuji hand picked Will because of his knowledge and popular method of teaching. He gave me quite the education of Andrew Rodney, and we will be doing a Skype video to clear up the confusion stirred up by Mr. Rodney (and others) for a YouTube video.

Mr. Rodney is critical of my neophyte misunderstanding of color, yet I know it very well. Mr. Rodney is not a professional photographer, and AdobeRGB did not take over the sRGB world in print volume worldwide, as Adobe wished it would. It does have a wider gamut but nobody will dispute that the equipment that exploits it is pale in comparison to sRGB equipment worldwide. And, nobody can dispute that if a typical photographer shoots JPG and uploads directly to the web or goes to wet process will need to change the color profile of an AdobeRGB file to sRGB for optimal display for common browsers.

I had a student at one of my workshops insist that AdobeRGB was better than sRGB, and I agreed with him. And I asked him to show us one of his prints, and the students commented that the red umbrella appeared dull. I then went on to explain how color clipping occurs, and this student got very angry. He said he much preferred the color of the AdobeRGB, and when I turned the paper over, it said, "Fuji Crystal Archive" - a wet process RA-4 printer paper used then exclusively by the Fuji Frontiers. I pointed out why the other students found his colors to be dull, and he became very angry. He absolutely insisted that his print had better color, so be it.

Color is subjective, but the application of the use of the most proper color space is not. You can create stunning prints with AdobeRGB and a continuous color management workflow that preserves it from generation to generation. And I am sure that those of you who do this from beginning to end earn the pride of enjoying your enhanced color. But you are not everybody, and the person who buys the Digital Rebel is at risk of reading experts decry that AdobeRGB is always better. It's not. Not in a hybrid workflow that starts with a wide gamut and ends with a narrow one.

This has gotten so intensely blown out of proportion that I am proud to announce that we will be doing a series of Skype interviews with top experts in photography and color management to address this.

I am super thankful to Will Crockett for giving me the run through about Rodney Andrew. Yes my responses have been very blunt, but it's because it is really something to see this kind of criticism when it is unfounded and unwarranted. And I am dedicated to bringing out clarity, and truth, especially about the history and background of Rodney Andrew.

To the moderators, please review your TOS, because I feel like a lot of these potshots in this thread violates it. And for the record, while I am of chinese descent, I do not speak chinese. English is my first language, and I can read it just fine.

The benefits of wide gamut working spaces on printed output:

This three part, 32 minute video covers why a wide gamut RGB working space like ProPhoto RGB can produce superior quality output to print.

Part 1 discusses how the supplied Gamut Test File was created and shows two prints output to an Epson 3880 using ProPhoto RGB and sRGB, how the deficiencies of sRGB gamut affects final output quality. Part 1 discusses what to look for on your own prints in terms of better color output. It also covers Photoshop’s Assign Profile command and how wide gamut spaces mishandled produce dull or over saturated colors due to user error.

Part 2 goes into detail about how to print two versions of the properly converted Gamut Test File file in Photoshop using Photoshop’s Print command to correctly setup the test files for output. It covers the Convert to Profile command for preparing test files for output to a lab.

Part 3 goes into color theory and illustrates why a wide gamut space produces not only move vibrant and saturated color but detail and color separation compared to a small gamut working space like sRGB.

Good monitors are only capable of the AdobRGB color space, many users around here on this site and elsewhere only have sRGB capable monitors.

The problem with your videos and others that I have view over the year skip the monitor color space viewing capability

Per your own quote......

"There are colors one can capture in raw and output that fall outside Adobe RGB (1998)"

So to make it simple I can capture a RAW image color that is in the ProPhotoRGB color space , my printer can print some of those ProPhotoRgb colors, but I can't see those ProPhotoRGB colors properly on my AdobeRGB limited monitor!!!

Thus I have this nice green color showing on my AdobeRGB color space limited monitor, no one told me that it is showing a clipped green of the actual ProPhotoRGB RAW image data green, and my printer is capable of printing that ProPhotoRBG RAW image data green. So now I print and what do I get, the actutal ProPhotRGB green that doesn't look anywhere near the AdobeRGB clipped monitor green and I say I wasted my time editing in a ProPhotRBG colorspace.........



For me I can't see editing in ProPhotoRGB at all. My take is to edit in AdobeRGB, view in AdobeRGB, and print the best it can as you also don't state that most printers can't even print the complete 100% sRGB or 100% AdobeRGB colorspaces.

We need a decently priced pro-sumerprinter that does print 100% AdobeRGB to match the editing and viewing in AdobeRGB and then most of us will be happy with our monitor to print matching.

Correct, and I do show how not to get trapped editing colors you may not see. We'll never have dispalys that are capable of showing all colors we might print (and vise versa). RGB working space are based on making color using light, prints use a subtractive color model. More below.
So to make it simple I can capture a RAW image color that is in the ProPhotoRGB color space , my printer can print some of those ProPhotoRgb colors, but I can't see those ProPhotoRGB colors properly on my AdobeRGB limited monitor!!!
Correct. It's a limitation but not a big one.

Do you print your images? If so, best thing to do would be to use the Gamut Test File, convert to Adobe RGB (1998) and make a print that way AND using ProPhoto, see what results.
We need a decently priced pro-sumerprinter that does print 100% AdobeRGB to match the editing and viewing in AdobeRGB and then most of us will be happy with our monitor to print matching.
Again, that will never happen. If you look at the shape of Adobe RGB (1998) which again is based on an emissive display and any printer gamut, you'll see a difference in shape of the color space somewhere.

One reason we need big RGB working spaces is that they are based on theoretical emissive devices (ProPhoto being very theoretical when you look at what falls outside human vision). Necessary because of their simple and predicable shapes. So while there are many more colors that can be defined in something like ProPhoto RGB than you could possibly print, we have to deal with a significant disconnect between these simple shapes of RGB working space and the vastly more complex shapes of an output color space. Simple RGB working space matrix profiles when plotted 3 dimensionally illustrate that they reach their maximum Chroma at high luminance levels which makes sense since they are based on increased Chroma by the addition of more light. The opposite is seen with print (output) color spaces where this is accomplished by adding ink: a subtractive color model. One reason we need such big RGB working space like ProPhoto RGB is due to its simple size and to counter the disconnect between mapping to the output space without potentially clipping colors. There can be issues where very dark colors of intense Chroma (which do occur in nature and we can capture with many devices) don’t map properly with a smaller working space. Many of these darker colors fall outside Adobe RGB (1998). When you encode using a smaller color space, you clip the colors to the degree that smooth gradations become solid blobs in print, again due to the dissimilar shapes and differences in how the two spaces relate to luminance. I suspect this is why Adobe picked ProPhoto RGB primaries for the processing color space in their raw converters.

That's the take home in the video and why large gamut RGB working space are necessary and why you may see, as I did, a smaller gamut working space will clip colors you can print and will result in inferior print quality. But again, you can now test this yourself as illustrated in the video and use my test files or your own.

One thing is certain, sRGB is the wrong working space for anything but posting to the web IF final print quality is important to you. Adobe RGB (1998) is going to be a lot better but how much so or less compared to ProPhoto depends on your images, your raw converter (for example, Aperture works in Adobe RGB so there's no benefit to ProPhoto), and your printer. Test it yourself. Let us know what you find.

Very interesting. It cleared up some misconceptions on my part.

Thanks!

(btw ... is this a recent video? I've watched quite a few of your videos, but I don't recall this one. I also was able to obtain your (out of print?) book via ILL).

Went up today.
Another BTW: Do you have an opinion on the 2014 book by Tom Ashe:

Color Management & Quality Output: Working with Color from Camera to Display to Print (The Digital Imaging Masters Series)


Your excellent Color Management book was published in 2005. I'm curious what you would update on it, and to what extent are parts obsolete, if any? (rude question?) PV2010? PV2012? ACPU? Or are those not applicable?

Haven’t read it so sorry no. But Tom's a good guy (he worked with X-rite).

Not interested in doing another book or update. PV2010/2012 are process differences in the ACR engine, not really color management per se. The theory hasn't changed a lick. There are newer applications like Lightroom (article on my web site about that), a few new instruments, but not a lot in terms of color management applications.
 
regarding the spheres, BTW I've been using those spheres for evaluations since they came out years ago, they are really neat for softproofing ICC printer profiles!

Tonight I compared ProPhotoRGB to AdobeRGB color space prints and I agree that the ProPhoto prints show smoother gradients with the spheres, subtle differences, but still there.

I then shot many objects around the home that had gradient colors using my Nikon D810 in RAW, converted all photos to both ProPhotoRGB and AdobeRGB and printed them. I couldn't find one set of photos with any differences, nothing.



Tomorrow I will shoot a few blue skies, perform the dual color space conversion, and print to see if there are any differences.

Bit odd ... the video shows the download as:
http://www.digitaldog.net/files/Gamut_Test_File_Flat.tif

but it downloads as:
http://www.digitaldog.net/files/Gamut_Test_File_Flat.tiff

(at least for me)
As long as it did download... that's good. Maybe you have something that added the extension? That isn't the video either. That's the TIFF for making the tests using it's native ProPhoto RGB and then sRGB after you convert. The video has a completely different name:

 
shot in RAW and converted to ProPhotoRGB and AdobeRGB, prints show very little differences, if any.

I shot about 100 photos yesterday, mostly of subjects with a lot of colors and really no differences between the ProPhotoRGB and AdobeRGB prints, using my Epson R3000 (same ink set as the 3880). I don't dispute that it's better to use the ProPhotoRGB color space but anyone using AdobeRGB isn't going to see any advantage unless the subject matter has major color gradients clearly defined.
