I leave the highlight blinkies on with a very short review time, but I only look at them when the lighting circumstances are difficult; most of the time I ignore the review until afterwards. The rendering of the review thumbnail is post-RAW conversion and to the JPEG settings current on the camera so it's only a rough guide and is only 8bit data. What the blinkies do is let me estimate where the camera thinks saturation values have gone out of bounds with the standard JPEG processing. I believe a pixel blinks at about value >240. I use it in difficult circumstances to judge where, spatially, I need to focus my concentration, and it gives me some point of reference to figure how much additional overhead I have to work with in RAW through experience. > Hope your show went well this weekend. Thank you for asking! The show went very well indeed. I believe we had over 100 visitors at the reception Friday evening and there was a steady stream of visitors all through the times I spent on site Saturday, Sunday and Monday. Lots of interesting conversation and comments. I photographed the installation formally on Sunday using the DA14 and tripod, haven't had a chance to process those images yet, but here are a few snapshots from Thursday evenings installation work: http://www.gdgphoto.com/wlbob/installation/ I already have work going into the next monthly group show at the same location (reception on Friday, announcement to come) and another solo show booked at the Zocalo Coffeehouse in San Leandro for August.
