This is a survey on how long it takes you to scan one transparency or negative on your scanner of choice, from start to finish. If your scanner allows you to scan several transparencies at a time, use the largest batch, and divide the time by the number of images in the batch. This would include any cleaning of the transparency, mounting, pre-scanning, scanner adjustments, cleaning up the scan of dust spots, re-cleaning up the transparency (if applicable), and maybe an initial rough matching of the color of the file to the transparency. What would be excluded is time spent waiting while the scanner does the final scan (since you can do something else), and the time to prepare a ready-to-print master file. Indicate your scanner, the total time, and if you wish, a break-up of time in different categories such as scanner adjustments, dusting, etc...
