from other manufacturers undoubtedly also can do this. It is done with the use of an infrared filter coupled with somewhat longer exposure times. There have been magazine articles on this subject. Here is the source of one of those.
Are there any dslr's on the market that can mimick or produce images like b+w shot on infrared or is a plug-in for photoshop the only alternative? I'm still shooting film and I'm almost always shooting on infrared but time, etc is against me and I'm able to spend very little time in the darkroom any more so I've been seriously considering going down the digital line. Thanks for any help anybody can give me!
