I live 15 minutes from the National Museum of the US Air Force. In the past 45 years I've been there four times and two of those times were this week. I'm testing the Merrill cameras and these were with either the DP1M or DP2M. ASA 200 shutter speeds as long as 10 seconds. Opened in SPP, exported as a 16 bit tiff, opened in LR and converted in SEFX Pro.
