You want this to be scientific? This is The Internet. :-) Well, the shot I have In Support of Tripod Use is this recent one: http://flic.kr/p/f2Kebj Obviously head fills the frame, landscape. Camera was about 8-9 feet away, 135mm at F8.0, ISO 200. Probably not the best tripod for the task, the ball head is a bit light for the DA* 50-135 + K20D: Manfrotto 190XproB, 486RC2 head. Here's a 100% crop of her right eyebrow and eyelashes: https://dl.dropboxusercontent.com/u/2254722/PDML/BMW_8026-crop.tif It's an 8-bit TIFF, exported from the original RAW shot in Lightroom 4. Lr's default zeroed settings except WB: flash and the default RAW sharpening of 25. -- -bmw -- 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.
