I'll make mistakes, and I can't magically avoid the difficulty of this, I was simply stating that I have an awareness of valid vs shoddy methodology.
You were going to use aperture to vary exposure mismatches between different sensors.
The problem is that you’re already making assumptions that have then been proven wrong in this very thread.
You’ve shown that you weren’t aware that the response can be different depending on aperture.
You tested for it and kind of announced in a way that didn’t seem to leave any wriggle room that you’d tested for it and there was a difference but it was negligible. (Hey you learned something!)
1. I had a problem
presenting the results.
2. The results do show, well, what they show. The proper files are now available. You can recreate those results.
Now you’ve done your tests at fixed apertures.
No, I haven't. I didn't re-do the test at all, I simply changed to way I saved the files I uploaded to my website. The edison bulbs in the background clearly reveal the differing apertures.
Then you kind of messed up again because the methodology was wrong, and people could immediately see something that you were dismissing as negligible.
Again, no. The exported files had a color shift. (Common problem/mistake.) I later posted files "closer to the iron." that, I think, stay true.
John, I won't address the rest of your comments other than to say:
1. Thank you for your involvement. I've rubbed you the wrong way, that was never my intent.
2. Even if it doesn't appear so, I'm listening, and I actually do admit when I'm proven wrong. (Plenty of record of that on this very forum.) I actually kind of find that fun.
3. The scientific method starts with a hypothesis (or a "claim").
4. I'll be busy prepping and shooting the tests tomorrow, and then it will take some time for me to make-ready for the online free-for-all, so don't expect much more on this topic for several days. That's not me slinking away...just doing the thing.
