Grainy Crystals From Skin Trying To Take Some IR Shots With A Canon 350d Using 100 Iso But They Are Coming Out Really Grainy?

Canon 350D is a digital camera with a CMOS chip, to ensure that information about the film and the means of their development have little meaning.
While the chip to see "in all digital cameras is a glass filter called a number of things, a hot mirror, hot glass, filter hot .. and is also called infrared-blocking filter. Depending on the intensity of the filter ... The camera must be harder for the infrared by what you have done, because the IR filter that you use in front of your goal. A 87C and MR-90 are completely black to the human eye, and not allow IR light. And if you have an IR filter in front of his lens .. Right?
The grain, as you say, the camera offers digital noise is probably the chip is forced to see how little it receives IR. While the flood refuse in the camera with infrared filter over the lens, it tries to filter on the chip inside is, too, so the chip is now trying to take more time exposure "in the dark, so to speak, give him what any digital camera on other than aCondition that) grain (or noise.
My Fuji S-2 is in this way, and I could not really anywhere. Changing the ISO has not done much good to some, but not much. I have 4 to 800 ISO to work "better", but always had a good amount of grain - .. Noise!
However, some cameras enable the IR cut filter before to remove (should be a fee of up to $ 3 500), but did after the shooting of the new shares will be resumed. Sigma is a camera with a removable IR filter anti-users. You can remove your car, then back on .. The Foveon ..
Fuji offered and still there, another pair of infrared cameras. One of them, called CSI forensic camera, the S-3 Iruvar and you can see in the infrared or ultraviolet, with appropriate filters. Without filtering the image above, everything is pink in color, but can be corrected in a good program for image processing. Nature of the work too heavy for a day: shooting Tho. The other is a Pro Fuji makes two very good work ..
There are a number of cameras that can be converted and Li ThoNCP bottom of this ..
I have the S-3 Iruvar and I'm still experimenting. B & W infrared is relatively simple, but requires more color you want. It is a filter # infrared light to wildly, and they are no longer cheap. So, believe it or not, so that a white light system can affect the outcome of your recording of IR, especially if the color ... A 25 a (dark) is also a good starting point if the device in the BW mode. A filter 29 is a still red, but you can still through. Under this background, the visual filter black leave "white" by a simple IR ..

IR shooting is one of these processes when they are in line with the "Book" returns done well developed negative, but with the grain, such as the nature of this film.
However, many experienced photographers special additives used in the development or use prewashed special "and develop procedures changed in order to soften the grain.
The photographers have spent a lot of research and tests, to see where the grain is acceteptable them and keep processes and additives, a mystery.
With a little research, you can be a part of their own ideas and access able to reduce the grain considerably in their views.
Fhotoace is correct, but has a digital camera. If you do not have the IR filter can not achieve true IR photos removed. You can not really replicate in Photoshop. If your camera will simply make infrared images, however. They may change yet, but he returned. Try this link if you are interested in the conversion of the camera.
