Very weird M8 image with IR filter

We were out testing the M8 with a 5d and photos of this black car with mettallic paint came out fine on the 5d but came out like glitter with the M8 I assume it must be the extra IR sensitivity is causing the metal particles to come out in the image even though it has the 486 IR filter on it ? Any other folks have had this type of thing happen.

I haven't seen that effect before, but wonder if the very overexposed reflection in the lower right center has something to do with it. It could be "blooming" or scattering.

If you still have access to the car, maybe you could photograph it again in different light to eliminate the reflection, then you could tell whether the issue is caused by the overexposure or the camera's response to the paint.
 
maybe it has something to do with the lack of AA filter on the M8. The tiny specular highlights in the fleck paint are diffused in the 5D due to the AA filter, but the M8 renders them like this?

Dunno. Wierd. Good reason to shoot cars on an overcast day (or under a giant softbox).

I sense a bit of jealousy in that comment :angel:

Were you shooting in RAW and did you process in C1? Double check to make sure both the 5D and M8 shots were equally exposed and shot at equivalent ISO. Given the scene I'd imagine the chances of getting severe underexposure due to the sun's reflections off the car are pretty good. If this was the case then you would of course you'd get more noise in the blacks.
 
The Paparazzi ain't going to be amused.
Not that one particularly cares for their sensationalism or operating methods;
but they were a photographic force of financial note -
as well as one group in the Press still using M cameras.
But that was in the times of shooting film.
I cannot see them readopting what would be the best camera in terms of size & discretion
if it cannot handle Popstars 's paintjobs.
For once, I hope this a photographer's test error & not a further footnote in the M8's IR/magenta malaise.
 
I once met a press photographer and was surprised to find his no.1 requirement was equipment that could get its data onto a laptop and off to the photodesk as quickly as possible using bluetooth, wifi etc. Picture quality and resolution were at the bottom of his wishlist as the shots were going to be "printed on toilet paper" anyway. Can't see him adopting the M8.
 
All i can say (without owning any high-end camera equipment) is that I can get this kind of results myself with the gear i own :rolleyes:
Well, but i would buy the M8 if i could :), even with all the problems that it has....

why should there be a hole in the shutter? do canon's shutter blades melt that easily?

I was thinking of the M8, not the Canon, but I'd forgotten that Leica finally made a metal shutter on the M8. In fact, that's an advantage people haven't mentioned too often about the M8 vs. earlier M's. You don't have to worry about burning a hole in your shutter curtain.

That might be putting it a little too blunt but I suspect/fear these IR filters may yet be found out to be less than a panacea for the problem. More like a pill for something, that has side effects and you need another pill to take care of those, and that one has side effects so you need another pill and on and on (been there!). We know the IR filters cause a color fringe in the corners on wide lenses that needs adjusting, so there might be other "side effects" yet to be seen once there is enough people shooting enough different things with them. There just might be a very good reason why no other manufacturer has made the same decision as Leica to go with a weak sensor filter :D
 
>I sense a bit of jealousy in that comment

Oh, no. I guess that you missed my previous postings about how much I dislike the M8 -- this after handling several at Photokina and after owning one for a week before I sent the thing back.
 
Weird image update

Weird image update

Hi folks,

I have uploaded another image shot at the same time not cropped just resized.

It is not noise it was set on 160 iso, and no its not dust either!

We were just playing around trying to get the reflections in on the car. The shots done with the 5d at the same spot on the tripod came out perfect!

It is summer here in Sydney and I have also had problems with hot pavements ( like 30 degress c in the sun days) coming out way overexposed? Anyone else having these issues.

Cheers Scott

Is it possible that he's seening micro-detail that he can't see in the 5D? :cool:

Definitely the M8 saw something that the 5D did not see, and it is not IR since it had been filterd, the question is did the photographer see the same or the M8 just imagined things, it would be the first digicam suffering from allucinations. :D
 
Or it could be just the part of IR spectrum right above filter's cutoff wavelength.
