| Ha Ha... even the 20D can freeze the motion of that guy The modded camera has indeed make IR photography more spontaneous for me. I used to have second and third thoughts about going out to shoot IR because of all the gears that I have to bring along. Now I just shoot whenever I feel like it. Hence the avalanche of IR pics from me recently. But this camera is still not as good as a modded DSLR like the D70 of deadpixel. The CCD of the D70 must be so much more sensitive than that of my Sony P200 judging from the shutter speeds of the shots he posted. I really envy those of you with D70s as you can now get them modded at minimal costs now that Matthew has learned how to do it. Apart from the size, the only advantages P200 has over a DSLR is the tremendous DOF eg. the Orchard street pics are all shot at f/2.8, and the ability to shoot IR video clips. |

| Hi, I am confused. I thought in order to take IR photo, it required very long expose time and very bright sunlight. But... that is not what I notice. How was it done? What is a Mod Camera? How come you can take picture of moving people and yet they don't appear as blur? Please do advise me. What IR filter are you using BTW? Any idea if my camera Pro815 camera can do that? Mine can only reach ISO 400 as stated in http://www.dpreview.com/reviews/specs/Sams...sung_pro815.asp . Pls advise. Thanks |

| For most of the DCs, a filter called a hot mirror is used to block most of the IR from the camera ccd. As IR would degrade the quality of "normal" photos. A modded DC refers to the removal of the AA filter (usually the hot mirror is combined with the AA filter, which is the anti aliasing filter). Without the hot mirror, the shutter speed would be much faster when taking IR photos Another way of modding a DC would be to replace the AA/hotmirror filter with an IR filter. For a consumer DC, not much advantage. But for a DSLR, u would be able to preview the scene in the viewfinder as the IR filter would not be blocking the lens. Hope this explains..... |
