| 00:05 | troy_s | alexML: So... dE is 4.05
|
| 00:05 | troy_s | Which might be an improvement.
|
| 00:12 | troy_s | Boo.
|
| 00:12 | troy_s | alexML: Sadly, it increased.
|
| 00:13 | troy_s | alexML: So after much futzing and twiddling and correcting, I am getting peak err = 14.417484, avg err = 4.054184 on yours
|
| 00:14 | troy_s | alexML: And peak err = 9.316373, avg err = 3.964185 off the original. So your tweaks made it worse.
|
| 00:14 | troy_s | The peak error is noticeably the more worse, which is quite a large margin.
|
| 00:15 | troy_s | Granted, se6astian|away really needs to _please_ give me some direct sun with direct sky 5000k shots of the Hutch, with nicely bracketed range from blown out to dark would be great.
|
| 00:15 | troy_s | se6astian|away: IT8 and the HCT are idea. The ColorChecker Passport, while a great little baseline, doesn't have spectro values and as a result, our guesswork is worse.
|
| 00:16 | troy_s | That said, all of irieger's work appears vastly solid in terms of twiddling the registers. A delta e of 3.9 on less-than-optimal sources is so much improved over the previous Alpha's results.
|
| 00:20 | troy_s | So, my gut says that the next working environment would be to see if irieger can offer up another set of tweaked values, and then gather the test chart data to A / B test them.
|
| 00:36 | Bertl_oO | yes
|
| 07:35 | Bertl_oO | off to bed now ... have a good one everyone!

| 09:58 | se6astian | good morning
|
| 10:02 | se6astian | troy_s: added to TODO list: https://wiki.apertus.org/index.php/AXIOM_Beta_TestsTODO
|
| 10:03 | se6astian | direct sunlight will be a rarity in the next couple of wheeks though I am afraid, but we will see what we can do :=
|
| 10:18 | alexML | right now it's sunny here :P
|
| 10:19 | troy_s | Even cloudy should be somewhere close.
|
| 10:20 | troy_s | Probably more on the high side due to catching blue sky and diffusing.
|
| 10:20 | alexML | yeah, and it's probably more likely to get an even illumination
|
| 10:20 | alexML | so I'd say try both
|
| 10:22 | troy_s | Direct will be even.
|
| 10:22 | troy_s | It is a ways away :)
|
| 10:22 | troy_s | But it also assures even distribution of spectrum, which will help tremendously as well.
|
| 10:23 | alexML | btw, we have some spectral response curves in the datasheet - would it help to calibrate from those curves?
|
| 10:23 | troy_s | Why am I up. Ugh.
|
| 10:23 | troy_s | Nope.
|
| 10:24 | troy_s | You are welcome to try, but they aren't a terribly reliable method.
|
| 10:25 | troy_s | (Hence why there are endless streams of threads on characterizing cameras out there. And by endless, I mean endless.)
|
| 10:25 | se6astian | we have the detailed response curve data from cmosis if that helps
|
| 10:32 | irieger | troy_s: As I'm done playing with the sensor registers for now I will shoot some color tests the next days. Will upload some stuff soon
|
| 10:34 | irieger | troy_s: Have to look at row noise but should hopefully be not that much of a problem
|
| 10:34 | troy_s | I think the averaging on the swatches settles most of the noise issues from the colorimetry side.
|
| 10:35 | troy_s | Fitting too.
|
| 10:35 | troy_s | The last batch puts us at 3.9 de on a matrix, which is pretty darn decent.
|
| 10:35 | irieger | jep. But it looked ugly on some of my last tests. Maybe it was just my FPN profile that went wrong.
|
| 10:35 | troy_s | Ah.
|
| 10:35 | troy_s | What were you using? A chart?
|
| 10:36 | troy_s | Also, I am more interested in those nether regions of non-linearity.
|
| 10:36 | troy_s | Because those are the ones that are going to cause the most problems shooting anyways.
|
| 10:36 | troy_s | (Ala rat urine colours in highlights on flesh.)
|
| 10:36 | irieger | for FPN? Dark frames and a (not ideal, small) grey card. Will shoot a exposure braket of the exposure chart with 1/6th of a stop steps
|
| 10:37 | irieger | 1/6th exposure steps are on the chart
|
| 10:37 | troy_s | Also, that wiki page isn't great advice.
|
| 10:41 | troy_s | (Typically the charts want to be shot hotter.)
|
| 10:44 | irieger | I would do some exposure brakets anyways
|
| 10:46 | troy_s | Yeppers.
|
| 10:47 | troy_s | I think that the matrix is likely darn close on the linear region. The only outliers will be in the non-linear, of which that higher light will probably be the most important. Possibly even consistent.
|
| 10:50 | irieger | Yes, I'm looking forward to see how it will go in all regions of the image.
|
| 10:52 | irieger | Would prefer not to have colored highlights too ;-)

|
| 21:07 | Bertl | some parts depend on phase 1 (volume orders) and we also need to test each Early Beta, but then it's time to ship them
