Lumariver Repro, or Basiccolor Input 6 Pro?on: June 26, 2021 at 2:54 pm
Well I’d say the landscape of camera profile has gotten a bit more complex since this thread was started. Lumariver Repro, Input6 and SpectraCore Camera Profiler (SCCP) are the 3 main options to consider. The licensing differences are quite complex but worth digging into if you are interested in making profiles for others. IMO, Input6 is the most mature and refined of these 3 products. It’s nice to use and has tons of great features. SCCP, however produces the lowest ∆E values and recently introduced DCP proifling in addition to ICC Profiles. Ultimately are you looking for cheap, good enough, easy to use or top notch quality? And at what price point with what profile licensing options? Either way you do this you’ll be getting great results, but your ∆E metrics may vary. Is Max∆E 3.0 meaningfully better than Max∆E4.5 or are you more concerned with average ∆E?…

Re: Canon 5Ds – anyone still shooting with it?Reply #1 on: January 23, 2021 at 12:56 pmBeen shooting the 5Ds since it came out and love it. Love the shift tilt lenses! Recently purchased the Fuji GFX100 and had a “Oh Sh*t” image quality moment. Can’t even look at my DSLR gear anymore…

Re: GFX 100 New Firmware – Pixel ShiftReply #2 on: January 23, 2021 at 12:53 pmPixel shift is the bomb! For what it’s worth Fuji left out some important information in their literature. Pixel shift mode changes and number of things including the shutter so that exposures that work with flash in single shot mode may not with in multi shot mode. They recommend 1/5 sec for flash sync in multi shot mode but I’ve found I have to lower it to half a second to get it to sync with my strobes. FYI!

Re: Chromix ICC Profiles via Polarized Light?Reply #3 on: January 23, 2021 at 12:48 pmSometime back I recall Mark alluding to Chromix ICC profiles as being created using a special polarized light source. I believe-but am not sure-that Chromix alludes to the process as “Deep Color” measurement which according to Chromix might be helpful if there is loss of shadow detail when one prints using matte paper. This Deep Color profile is said to be produced with a “slower instrument with versatile measurement options. One of these measurement functions tends to draw all the shadow detail that is possible to achieve in a profile”.
Some of my images look better on matte papers and I am intrigued by the claims posted by Chromix which certainly has an excellent reputation.
I wonder if any have tried Chromix “Deep Color” profiles and if such ICC profiles deliver on the promise of increased shadow separation.
In general, does the use of a polarized light source make a difference in ANY ICC profile?
I would argue that polarized measurements really only provide a meaningful improvement for textured surfaces where spectral highlights and reflections can otherwise screw up the measurement process. Glossy canvas is an excellent example where we see significant improvements.
There are a lots of common misunderstandings about polarized measurements, especially how to interpret gamut renderings. There is no “deep color” to be uncovered with M3 mode for example. I have some discussion on this with visual samples one can view at https://www.on-sight.com/xrite-i1pro3-review/

Re: Transmissive Printer Profiling in X-Rite i1ProfilerReply #4 on: January 23, 2021 at 12:41 pmI think it’s worth saying that while there are many older instruments and applications that support transmissive profiling, XRite has introduced some all new color science into the transmissive profiling process with i1Profiler3 and the i1Pro3+ and the results are better than I’ve even seen before. And yes, you can do it with or without the iO table, but a lightable is required for either. I have a short review with details and examples one can view at https://www.on-sight.com/xrite-i1pro3-review/
