rick123 Posted November 23, 2006 Share #1 Posted November 23, 2006 Advertisement (gone after registration) Hi everyone, I was wondering if members of the forum who own M8's and have IR filters would be willing to shoot some side-by-side comparison shots with and without filters to better determine the effects of using a filter (i.e. the effect on other colors besides black/magenta)? Thanks! Rick Link to post Share on other sites More sharing options...
Advertisement Posted November 23, 2006 Posted November 23, 2006 Hi rick123, Take a look here Do You Think It Would Be Helpful To Do A Filter/Non-Filter M8 Test?. I'm sure you'll find what you were looking for!
mike prevette Posted November 23, 2006 Share #2 Posted November 23, 2006 wow, where have you been? Go take a look at some of Guy's posts. He's done an amazing job at just what you've asked for. -mike Link to post Share on other sites More sharing options...
osera Posted November 23, 2006 Share #3 Posted November 23, 2006 Rick- There have been some interesting images posted on this forum. You could check these threads: http://www.leica-camera-user.com/digital-forum/9932-green-test.html http://www.leica-camera-user.com/digital-forum/9637-new-m8-profiles-c1-instructions-4.html If there is another type of comparison you think would be helpful or revealing beyond what was shown there, post some suggestions. I and others do have some filters and could try some different types of comparisons. Regards, Allen Link to post Share on other sites More sharing options...
ChrisC Posted November 23, 2006 Share #4 Posted November 23, 2006 Indeed, where have you been while we were enduring roller coaster rides? Guy Mancuso has posted many test shots. If you're quick; only one page back is 'GREEN TEST' which is a good starting point for you. Dig back a few days, there's lots of excellent stuff to read. Sincerely......................Chris.

frc Posted November 23, 2006 Share #5 Posted November 23, 2006 Answer: NO! I do not think it would be helpfull to mount an extra glass element in front of my Leica glass. Therefor testing it is pointless in my opinion. IR filtering should be done properly inside the camera. When so, I'll buy. Sorry for reacting in this way but I'm getting fed up with all these so called solutions. The camera should work well flat out. Link to post Share on other sites More sharing options...
rick123 Posted November 23, 2006 Author Share #6 Posted November 23, 2006 Thanks Allen! Other than an occasional UVa filter on a windy day, I do not normally use a filter on my M lens. I guess I am still concerned about the possible effect(s) on natural color rendition as I decide on whether I should purchase the M8. My M6 and D-Lux 2 still are looking good!

The camera should work well flat out. frc, It has already been demonstrated that it is helpful, indeed delivering unexpected benefits, to mount IR cut filters in front of Leica glass, on the M8. The testing done so far, combined with technical knowhow, demonstrates that increasing the IR filtration in camera on the M8 would be counter intuitive to your precious Leica glass. The camera does work well flat out, but like any highly developed and finely tuned 'racehorse', it needs more than usual skill and careful use, to take it the extra distance. Mediocre shooters will probably not get a great deal of improvement from this camera, whatever its fix..\ The so called solutions you are so fed up with in fact are extremely helpful, so far, for those of us who are trying to tame the beast. Perhaps a P&S is more in your line of comfort. Personally, I fing my LC1/D2 a lot easier, at present, to match colours, but that is as far as it goes. After that, the ease wears off and the M8 powers ahead. Cheers, Erl Link to post Share on other sites More sharing options...
osera Posted November 23, 2006 Share #8 Posted November 23, 2006 Rick- Well, there is definitely an effect on color rendition with the current profiles for RAW conversion, in addition to a cyan vignetting on wide angles, increasing with increasing FOV. The use of the filters will require new profiles. I don't have any experience with in camera jpegs, but I guess they will have to take into account the presence of the filter somehow. As far as the use of a filter vs. no filter (for UV or physical protection), that is, as I'm sure you know, a classic controversy with strongly held opinions. I wouldn't recommend bringing that up. -Allen Link to post Share on other sites More sharing options...
frc Posted November 23, 2006 Share #9 Posted November 23, 2006 Hi Erl. My racehorse is called MP, it devoures film, rolls a day. It focuses through the lux 35 asph or any of the other piece of glass it needs. No filter required, not even for spam, if there's a pink elephant in the picture, there was one in real life. Don't get me wrong, my Leica M is my p&s, simple, intuitive and dependable. Perhaps, although I love PS ( different from p&s ) I suppose I'm just more a film bloke. Digi for the technicians, film for the simple folks, come on, rubbish. Many Leica lenses give very nasty effects when used with filters, the lux 35 asph produces ghost images when there are light sources in the frame. I mainly do documentary stuff, I do not always have the choice to wait for a nice light situation, otherwise: beautiful light, scene gone. Just disappointed, as I said before. Unless the cam does the job right out of the box, no matter how good when "tuned", the M8 is only a studio- or landscape tool, and of no use to me. regards, Fr.

frc Posted November 23, 2006 Share #10 Posted November 23, 2006 Uhhhhhh Allen, Is mine one of these classic strongly held controversial opinions? I'm damn serious about the filter issue, want digital workflow all the way, but I'm not buying as long as a filter is required. Cheers, p&s-Fr. ;-) Link to post Share on other sites More sharing options...
erl Posted November 23, 2006 Share #11 Posted November 23, 2006 fr, I respect your right to hold your views and I identify with your MP/film combo. For me me it is the M7. Again, the differences between them are what serves us bests, with our differences. I have never favoured filters, except for B&W work on occassions. But this IR cut filter, I am told, definately improves image definition, if that is important. We have both analyzed and decided. Good shooting to us both.
