No IR filter? For colour? Really?

Is your friend really THAT orange?:confused:

My monitor must be horribly calibrated, because he doesn't look orange to me at all. It was shot under hideous fluorescent lighting, but it looks accurate to my eye. Or are you just being a smart-ass? :confused:
 
I do not have a M8, but a R-D1, which also has the IR issue, albeit much less pronounced. The only time I really felt the color shift was when shooting ember in a barbecue. Used the tone select in PS to change the hue and it came out acceptable. But in a scene with a lot of details and/or lots of IR/magenta issues it'd be really a waste of time, the mending would become too fake.

If the M8 has this big issue with IR, users should accept it and get the filters, no point in having good lenses but shoot LSD high photos.
 
I can only say that I found many instances of IR color shifting with the M8 not just black synthetics, and as someone who disdains post-processing as much as a pre-colonoscopy laxative prep, the IR filters (with coding for lenses <35mm) are an effective and simple solution. In fact they correct IR color casts better than whatever Leica did to the M9 (based on one afternoon of shooting one, in all fairness). I've always kept a UV filter on my expensive lenses in the past, so aside from the cost and the funky red color, I'm happy there was such a solution possible.
 
Photo is fine

to my eyes Maggie.

I believe Jaapv is sincere, but sees IR artifacts in other peoples images that just are not there, or are non IR artifacts (WB, etc.).

This is just IMHO.

JaapV, the sensor records more colors as we can see, but in the reproduction it shows IR reflective materials as purple. That is how I understood several articles about it. But I might be corrected :) But if it is recorded in the DNG as being a purple color, Jamie Roberts has found a pretty good way of separating them from other purples.

this is your post, I guess? So you've been using that profile as well?

Anyhow, until I get my IR filters (and one E48 will take a long, long time) I will shoot purple-blacks. And since the E48 is on a 6 weeks wait, I'm off, gonna try to find how to implement the ICC in C1.
 
Maybe everyone looks orange to the Dutch, what with all those Gold Medals they brought home in Speed Skating?
 
Lol!

Lol!

and I'll bet that the coach who gave wrong lane advice to one of the winning skaters is going to be orange/red faced no many how many IR/UV filters stacked up on a lens ;)

Too bad that GaAS Sensors are so expensive. Remember when the Nikon FM, Pentax MX, and Konica FS-1 used Gallium Arsenide PhotoDiodes for their meter, rather than silicon cells just for this reason? The material of the detector was not as sensitive to IR past ~8,000Ansgtroms. The Dye used in the RGB Mosaic Filters do a decent job out to that region.

If you want to make cameras for Visible photography, they should come up with some material suitable for the detectors.
