Camera: Minolta D7IR Filter: none Exposure time: 1/350 F-stop: 6.7 ISO speed: 100 Focal length: 7.2695 White Balance: manual EV: 13.9395EV comments: Strange! The modified camera meters the scene exactly the same as the stock D7, but the photo is brighter. So the camera is somehow metering differently. Either I goofed up or the green leaves had some influence due to "IR contamination" - they are very bright in IR light as you can see below. |
