geogphotos Posted April 22, 2023 Share Posted April 22, 2023 This was one shot and somehow has produced two RAW files. I've never seen this before. Any ideas? The picture was taken through a glass window from a bus. Link to comment Share on other sites More sharing options...
Allan Bell Posted April 22, 2023 Share Posted April 22, 2023 Totally flummoxed. A developing fault in the camera firmware maybe? (Not developing as in developing image). Or an intermittent connection fault in Camera? Sorry can't really help but interesting and will keep an eye on the thread. Allan Link to comment Share on other sites More sharing options...

DJ Myford Posted April 22, 2023 Share Posted April 22, 2023 What has happened seems clear, but why would be pure speculation. The red and blue channels have been output as one file to produce the magenta image, and the green channel has for some reason been allocated to a separate file. You may be able to merge the channels in PS to recover the image. Possible reasons are potentially endless, but if it happens again I would suggest reinstalling the camera's firmware if that is possible. If you were on a moving vehicle a jolt could have caused a brief interruption of power, but I would have expected that to just generate a corrupted file. You could go as far as suggesting a cosmic ray passed through the chip and flipped a bit at just the wrong time: diagnosis on an isolated event is very difficult.

Harry Harrison Posted April 23, 2023 Share Posted April 23, 2023 You could try to recreate it I suppose, pretty sure my Fujis continue to write to the card after you switch the camera off and then finally they do switch off. Link to comment Share on other sites More sharing options...
DJ Myford Posted April 23, 2023 Share Posted April 23, 2023 There are probably other ways for it to happen, but the only one that really makes sense to me is that the green sensor data got saved to the next image buffer. There must be a register somewhere in the processor which identifies the active buffer. If the data in that register is incremented prematurely after only two colour channels have been read, it would point to the next buffer, and the final channel data would be directed there. As each buffer holds an image, each is output as a separate file to the removable media. But the question would still remain, why did the buffer pointer increment after only two channels were read?

Cal Posted April 23, 2023 Share Posted April 23, 2023 Either something in the camera image processor glitched or perhaps a cosmic ray struck it while the image was writing to cards and caused the glitch. No, I'm not joking. It is possible. Link to comment Share on other sites More sharing options...

DJ Myford Posted April 25, 2023 Share Posted April 25, 2023 Solar activity is moderately high at the moment - as evidenced by the auroral displays - so that can't be totally ruled out. If the image was captured on the 21st, there was an M1.7 solar flare on that day. Prior to that there was a more powerful X1.2 on 29/3. Of course, any match with the date of a flare would probably be coincidental, but you never know. Link to comment Share on other sites More sharing options...
