This case is a poster child for the unutterable sleaziness of corporate business practices in this day and age.  My only wish is (a) that the photographer gets her entire judgment against these sleazeballs and (b) that everyone who has "licensed" one of her images from Getty joins in a fraud class action against said sleazeballs.

What do you want the T/S for? Shift for architecture? Tilt for landscapes?  Wide angle or normal/tele?  Personal/family or business/photo trip?

Since you mentioned the Samyang, I'll guess wide-angle, and Italy makes me think architecture...  The Samyang isn't very sharp in the outer image circle, so probably won't have any advantage over correcting the 16-35 in post.  Also, you can use the VR in some circumstances and not be hassled for using a tripod.

If you're looking for tilt to get infinite-plane type landscapes in focus, that's only one type of shot where you'll see a benefit for the price of carrying that extra lens.

The Nikon gets trash-talked a lot, but it's very sharp within limits.  Also, adjusting the axes to be parallel really only benefits one type of shot where you want to exaggerate near-far relationships on the ground plane. (Shift down and tilt forward.)  The default perpendicular arrangement has a couple uses: 
1. Shooting a building at an oblique angle. (Vertical rise with horizontal swing)
2. Landscape horizontal shift pano with forward tilt.

There is detail on using Photoshop at the end of the paper which recommends the ROMM ICC profile, which is v4 compliant, unlike the standard sRGB. The large gamut ROMM profile contains this expanded PRM gamut which can then be printed or proofed. They have some pretty wireframe graphs showing the gamut expansion.
That's the problem with the use of the PRMG in my view. If you want perceptual (i.e. compression only) rather than saturation intent (compression & expansion), you are out of luck.

You get a much better defined and accurate transformation using a device link or device profile with a source space specific perceptual (or whatever) gamut mapping, rather than relying on the PRMG fudge.

I'm considering a T/S lens for a trip to Italy.  I've wanted to own one, but never had the right impetus.  I've played with them, but if I take it with me, I want time to learn it for a few months before I go.  And if I get the Nikon, I will need time to ensure it gets fixed to reorient the movement axis. So some questions.

My Basic Kit is:

Nikon D810
Nikon 16-35mm f/4 VR
Nikon 24-70mm f/2.8
Nikon 70-200mm f/2.8

1) Will a T/S be worthwhile in for this trip?
2) What focal length would be best?
3) What actual model would you recommend.  The Samyang seems to get decent reviews, but...

It looks very much like drastic over-inking to me as well, not any kind of dithering artifact or anything that would be caused by ICC profiles. Is there any chance at all those blotched prints are from the back side of the paper?

Thank for the clarification. Yes, by "channel" I did mean R,G,B channels and by one per channel I meant effectively a diagonal matrix.

unlike subtractive math mess in Foveon you are quite fine with a single multiplier for a true raw ("RGB" model) channel... in any case a proper implementation shall write illumination spectrum + CFA transmission spectral data + optics spectral transmission + whatever else required...

So by "each illuminant" that would be a separate .dcp for each illuminant?

and in DNG container you can store multiple dcp profiles inside... so you can have a raw file written by a camera firmware in DNG format with as many profiles tuned for as many illuminants as you want...

You could try:

Decal Paper

You should be able to get any acrylic supplier to sell you blank stock.

You can find a good looking gallery labeling system here:

Gallery Labels

Try a search for "small acrylic museum labels"

Good luck.

So you've never screwed up a photo shoot...never delivered something that you could have done better...something another photog would have done better.

Adobe rectified the issue in good time which is all we could really ask once the product was released with this issue.

I'll refer you to my earlier comment:

Please spare me the lecture on nothing is perfect and how difficult Adobe's job is ... if you have been following the thread, you would have observed that I do not now, nor have I ever, expected perfection from Adobe or any other entity.

Yes, all software has bugs. But this latest bug wasn't a peculiar outlier that only affected a few end users with oddball configurations ... this bug was problem for EACH AND EVERY USER OF OS X who wished to print with the application controlling the color management.

I know a coders job is difficult. That is why I buy software licenses instead of developing my own apps. It also doesn't explain how other developers with far fewer resources updated the Apple API's and resulted in no issues for their end users to print properly.

I go to great efforts to produce photos, graphic designs and other services that my clients don't aspire to provide for themselves.

While I know I don't achieve pure perfection either ... I do have a QA/QC system in place so that the products I produce meet a minimum requirement ... before those products and/or services are delivered.

More importantly, when a problem arises ... my fist effort is not to point my finger at someone else. I take responsibility and remedy the situation to the best of my ability and don't try to rationalize that my customers should accept a certain level of poor quality work because my job is difficult to perform.

As I have said before, Adobe would very likely have not had to go through the steps to rectify the situation (Something I clearly said I appreciated) if they had applied just a bit more thorough inspection before they released v2015.6 ... there was no set in stone deadline to update the printing APIs for OS X. There was no rush to offer this update due to outside forces ... if it took another update cycle or two to ensure it was more stable and less problematic, wouldn't that have been better for everyone?

This is an excellent effort.  Was recently gone for 2 1/2 months away from the studio on a wilderness shoot - I could really have used this.

Thankfully the two printers left plugged in and running were HP Z Series printers and the micro-drip technology worked quite well but not perfect.

When I printed a diagnostic chart, first thing, the Magenta rectangle representing the magenta print head was missing.  Ended up replacing that printhead but that was about all.

I think your program would have saved that expense and the printers would have been functioning perfectly once back home after that Long period away from them..

Thanks for creating this.

Had to call Epson for help with my new P800. I had the same experience I had with Epson support and my 3800 - fabulous. I wish all customer service was this good. They know their stuff.
