IR-cut filter's effect

For those who have not yet slap the IR-cut filter onto your M8, I can assure you that you will be pleasingly surprised. Not only is the color cast fixed, the sharpness and clarity of the Leica lenses are brought forth in full flavors. You know about my whinings and "coughing out of blood" regarding my M8 before the filters but with my new B+W 486 filters, I must say that I'm a lot happier.

It is a pity that Leica tried to position the magenta cast as something you only see with artificial fabrics. In fact, the IR is everywhere and the lens projects an out of focus haze over the image. I think the combination of filters and firmware support for them will really move the game on.

Honestly i think the filters improve the sharpness of the lenses and almost all my images actually benefit color wise from it. I hate filters like the next guy but if there doing something good than i have no arguements against them and i am well over 12000 images with them between my 2 bodies . But i agree with Mark it should have not been said just to improve the magenta cast. We just need 1.10 now for the wides, that part with the cyan cast is a issue

They have a positive effect on black and white images too. Sharper, and the veiling flare like IR contamination is removed, resulting in richer darks.

I myself prefer no filter for B&W (matter of taste).

I would expect apparent increased sharpness of images when the IR-cut filters are in place. The lens cannot focus both the IR and the visible spectrum in the same plane.

 

Removing the IR should render images with less smearing.

 

I think, however, I would like to do some experimenting with IR photog using this camera. There a filter shedding activity in my future. First a book or two on the subject, then some recreation.

 

This could be the subject of a very interesting thread.

Sean, welcome home? Are you biked out?

 

Good to hear from you.

Certainly a matter of taste, as the IR will, on the other hand, "lift"the shadows, making for a flatter contrast, which can be very helpful. And sharpness is, of course, relevant only in the context of the subject matter.

I agree. I fought using the filters as well. For color shots I can really see a difference. For b&w I agree with Sean, there is something I like better without the filter. Here is a shot from Saturday with the Noctilux using the filter, firmware 1.092 and no color or white balance manipulation. Shot in DNG iso 320 f2. The only light were the incandescents in the ceiling, and light through the stained glass.
