Very weird M8 image with IR filter

.............. 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
How about several high end MF digital backs out there using the same weak filters and also needing IR cut filters on the lens.........:)
 
Its maybe just Weird paint

Sorry everyone, no conspiriacy here. It was Mazda 3 in jet black paint , two of us were there and neither of us saw what showed up in the end images. Saved as both Raw and Jpeg. I have uploaded the Raw converted to jpeg with no manipulation.

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.....

the exposure meter is "heavy centerweighted" ... so what is in the middle of the frame has huge influence on the exposure.
I have routinuously -1/3 or -2/3 EV dialed in.
Use exposure lock by halfpressing the shutter .. point for middle gray!!
Or ....you perhaps locked exposure without knowing because you have your finger resting on the shutter ... it needs very little pressure to lock

i do not know what you are looking at .. but i am looking at a several stops overexposed crop .....

Thanks, Scott. I'm always suspecting compression or processing effects. If you didn't see the sparkly effect in the raw, that rules that out! I do see effects of the jpeg compression in the uploaded images (both on the area with the "sparkles" and in other areas of the images -- note the little "blocks" within which compression seems to be done, most easily seen at, say, 500% magnification) but it does seem clear something else is going on as well.

Veeeery interesting... -- Michael

All I want to know is how well the M8 will allow me to do Macro work at the business end of an arch welder. If it will not perform under these circumstances then I am not interested- what the hell was Leica thinking?

This camera has a lot in common with Digital Hassy backs or so it seems- and we all know how incapable those medium format digital cameras are.

Now you are a bit excessive, taking pictures of shiny cars is really not an extremely exotic thing to do.
Or are you suggesting that good photographers obviously take care to avoid having shiny cars in the frame when they are out street shooting? :p
 
M8 is not a meidum format back. It is also not an aircraft gunfire recording camera. Nor an endoscopy tool.

Last time I checked it was a general purpose small format camera intended to work well in uncontrolled light conditions. There are cameras that do that part well already, I don't see the point comparing M8 to an obscure specialised rig that has a similar shortcoming, sorry.

How many street-shooter you have seen lately with a MF back?

MF backs are normally reserved for shooting under controlled lighting conditions, a Leica M is usually the tool of choice for street shooting, there is a big difference here.

You want an M body to be able to cope with anything, reduction of versatility should not be accepted as a compromise.

Everyone, since Leica intoduced the 35mm format ,knew that it was not the ultimate image quality tool, any decent MF camera is able to beat the c**p out of any M body; size, versatility and reliability, together a good (but not the best in absolute terms) image quality, are what made Leica the ultimate street camera.

Streetshooting is dead business... look at the people who addopted the M8 .. they did it for the ultimate imaquality and nothing else..... there are no other reasons than ultimate imagequality to justify buying $3000 Leica lenses to fit it.

And i repeat again, knowing it is preaching in the wrong church, for streetshooting ... (and that is about all that i shoot myself) .. there are no colorissues and IR filters are not needeed ........ assuming you shoot raw and use a proper profile.

I ordered my 2 free filters .. but they will probably end up in the drawer, unused!

There a many people bashing the M8 because they simply lack the skills to process the files properly ...... it is no point & shoot .. and it never will be!

I am not aware of a profile that is able to distinguish reliably between purples due to IR and real purples of similar shade, probably, despite shooting only RAW with an R-D1, a 20D and an LX1, I am one of the guys that "lack the skills to process the files properly";)

Since you know one please share it with us, and maybe with Leica, they could save a lot of money sending a free profile instead of two free filters. :p

Over on the Leica User forum there are a few guys who are very experienced with processing and have been doing a great deal of experimentation with profiles and processing and have only been able to partially counteract the purple cast. Leica, working with Phase One, have not been able to come up with a firmware/profile/processing solution, which I presume is why Leica is going to the expense of absorbing the cost of 2 filters for each M8 they are trying to sell. If you know what none of them do, please for the love of Mike, step up and reveal your workflow. It would save everyone a lot of money and might even save Leica as a company because free filters or not, there are a lot of people who've lost interest in the M8 as a result. I don't get around all that much and I've talked with at least 2 dozen guys who were going to buy one but aren't now.
 
I guess if it were not for the M8 a handful of photogs (mostly R-D1 jocks) would have little to discuss here in the Leica M8 room- YUCK!!!! The Leica M8 is a different animal that is attempting greatness by forcing fewer compromises and requiring of it's photog... more. More thought about the shot (do I use an IR cut filter? YES, do I need to work on this shot in PS (or what ever program they like- SOMETIMES, etc). This is also the same questions Hassy digi back photogs ask themselves and guess what- Leica M8 images look very similar IN PRINT to Hassy prints.

For me it's really very simple. I have to shoot with a RF- I do not like the interface of a DSLR, I do not like the mirror slap, I do not like the bulk of a DSLR, I do not like DSLR's in general and so I must have a DRF or it's back to film and I don't much care for film anymore. So at the moment I have two choices- the Epson R-D1s (getting a little long in the tooth but I love mine- despite its horrific RF issues) or the Leica M8 (has issues, similar to the Epson but with a much higher envelope potential in terms of image quality.

This thread is a little different in that it appears the digital sensor picked up some metal fleck in the paint presumably due to the M8’s high IR sensitivity. This however has digressed into the same IR shift, no set of software tweaks can fix (THAT’S NOT THE FIX IT’S FILTERS), and on and on. Really if you all hate the M8 so much why not just get a Canon DSLR and be done with it? If this forum exists for some to voice their opinion regarding the M8 expect me to defend my only other DRF option and to point out the obvious holes in some people’s arguments.

Yea well if such a profile does exist I want to know as many of my shots taken in Hong Kong have a suspicious "red shift" on black... drum roll please... all shot on an R-D1s!

I guess I'll just have to go out and purchase a half dozen IR cut filters and then see if I can foment some hate threads for my beloved R-D1... NOT!

Yes, it is irrefutable, scientific, conclusive evidence. I also think the synthetic clothing and black car-paint industry are in their golden era. I mean, purple era.

This is what happens when the amount of people skipping Physics class has exploded beyond critical mass.

Nobody likes an "elitist", Ted. You can only hate "expensive" things. :angel:

I guess we were all too busy bashing the RF calibration and shutter unreliability of the R-D1 to waste any time with the (visibly minor) IR sensitivity issue.
