comment Same Ink Different Paper - wildly different color gamut?
This makes a lot of sense, but I'm very surprised it's Epson's own profile that is so far out of whack. Your suggestion to try the same profile on both papers is excellent. I'll do that this evening and report the results.

comment What is the Base ISO of a Canon 5D MK III?
I don't really do anything special. Unless you're seriously underexposed the actual difference isn't going to be visible in a print and I just don't worry about it. It's all empirical and gut feel.

comment What is the Base ISO of a Canon 5D MK III?
Not taken as snarky :-) I don't have a source, just observations and experience. It seems that the histogram and blinkies are derived from the 1-megapixel preview jpeg that is displayed on the rear screen, which makes for some interesting questions. At that size each display pixel contains 22 image pixels, so it would be useful to know how those 22 pixels are combined (average? maximum? something else?) to derive data points for the histogram.

comment What is the Base ISO of a Canon 5D MK III?
I have a Canon 5D3 and find that the blinkies and LV histogram, being based on a quickie JPEG conversion, are not at all accurate in detecting RAW saturation. Even with a histogram showing significant (say 1/2 stop) overexposure, there's still plenty of headroom to extract a well-balanced image from the RAW file. While ETTR is clearly the best way to maximize image quality, the techniques describe in the linked articles are a little simplistic.

comment Why don't cameras support journaled filesystems?
The error here was keeping 1000 photos on a card without backing up. If traveling to a remote location where you will be without access to a computer on which to backup you should be carrying a backup device.

comment Lightroom EXPORT not recognized by external programs
Did you export as PSD? I believe the PSD file can contain an edit history.

comment Is RAW worth the effort if using simple editing tools (e.g. iPhoto)
Once you try RAW and see how much you gain in editing (WB, dynamic range, etc) you'll never want to shoot anything else. You should download the 30-day trial of Lightroom and look for deals (I saw it for $109 last Friday, forget where though).

comment Why is focal length measured in millimeters?
If you read any Ansel Adams, you'll find that focal lengths for lenses on his earlier plate cameras were all measured in inches.

comment Have inkjet prints surpassed chemistry-based paper prints in terms of color gamut?
@StanRogers Good question. I assumed that the profile was showing me the gamut limits and the maximum possible saturation. I will try adjusting the proof tonight but I don't expect to be able to improve it much if the proof is already showing me the deepest red/orange possible.

comment Have inkjet prints surpassed chemistry-based paper prints in terms of color gamut?
Well, in my case the soft-proof and test prints were both unacceptable, I was just unwilling to accept that my "intuition" about chemistry-based paper was that flat-out wrong. And WHCC specifically does not do any color correction unless you ask for and pay for it. They are used to dealing with people who understand color management.
