I was shooting RAW mode and importing into ACR/CS5, then converting to .TIFF with no noise reduction. My largest question was really, how much MAY/MIGHT length of exposure and the camera being in a continuous 'power-on' state affect noise levels and how will that differ from noise level tests like on dpreview? I had taken 5 10-second shots and stacked them and was shocked at how much noise was visible. Granted it will be 5x the amount of noise in one shot, but the results were basically unusable and it was noise on a black background, so extremely visible. I know I could have a done a dark frame subtraction... it was just surprising to see the noise level. As far as why the camera did not take the 10 shots as instructed with the intervalometer, and only took 5, I assume it's as the manual states 'if the interval setting is too short and the previous image processing cannot be completed before taking the next picture, no picture may be taken'. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
