any digital infrared shooters? sony
hi,
i have a DSC-V3 and notice that if you set it to "night shot" mode, you are in effect, removing the ir blocker in the camera. of course it's way too bright to get a pic like that in daylight, but i do have an old wratter 87 filter that i put in front of the lens and it works...kind of. the image gets way too blown out in the highlights (foliage), even though the sky darkens nicely. it seems that the only way you can shoot this way is in program mode, so all i can do is try to reduce the exposure a little with the compensation. it really doesn't do all that much. even throwing a red filter in front of the 87 didn't do much to alter the highlights. anyone in here shoot IR with these Sony cameras, and have an answer for me? I guess i could double up on the filters, but that seems a tad redundant. thanks |

Craig yep, the minute i sent my post i went and grabbed a polariser, and it did the same thing. i guess a two stop--at least--ND would do the trick? thanks |

I guess i could double up on the filters, but that seems a tad redundant. thanks I've shot IR with the F717, now the F828. Try a strong ND filter in addition to the IR pass filter. Even better try a - get this - a Hoya X1 or similar GREEN filter. Consider: We've already selected visible light out and IR in, now we need to control the amount of IR that gets to the sensor. Turns out that the green filter I tried is much more efficient than a 2 or 3 stop ND filter at just that task. A downside is the need to have a blob of filters stacked up front. This causes vignetting at the wide end of the zoom range. Using polarizers gives more fine control but adds even more filters to the front. With Sony's refusal to let their firmware be modded to give full exposure and shutter speed control under "NightShot" mode, we're limited to f2-ish and 1/60sec. limitations (1/30 for the 828 -grrrr). But it's still a neat camera to take IR with. No need to remove the hot mirror, and full use of the live *preview* including histogram. http://www.unclaimedmysteries.net/di...s.php#infrared Corry -- It Came From Corry Lee Smith's Unclaimed Mysteries. http://www.unclaimedmysteries.net "You didn't chose to address any of my post except this last little piece where I ridiculing you for being an idiot." - "Altie" on rec.sport.football.college, 2006 |

Sony priggishly tries to prevent "X-Ray" photos - but IR does a VERY poor job of "seeing through clothes". I've taken some wonderful landscape footage with an old TRV-9 Mini-DV camcorder and IR+red filter (before Sony crippled this great feature in late TRV-9s). But it's still a neat camera to take IR with.

I found I couldn't get sharp IR images with my Sony 707. I guess your idea of stitching several images together (thus reducing magnification) is a good one for getting nicer-looking images. -- David Ruether http://www.ferrario.com/ruether |
