Number of photographs: 14, exposure times (shutter speeds): 1/1000 second to 8 seconds, f-stop: f/8, equivalent sensitivity: 200 ASA; dynamic range: 163,147:1, radiosity: 342. Assembled with auto alignment in Picturenaut 1.18b, white balancing in HDRShop. The wall left to the light switch was taken as reference for white. Both tone-mapped in Artizen 2.4.12 with the Reinhard operator: Luminosity: 1.00 Saturation: 0.00 Contrast: 0.50 Highlights: 0.00 Shadows: 0.00 Midtones: 0.20 This picture was differently assembled than the one shown in the introduction to the topic. The series of photographs is the same. The HDRI shown in the chapter «Tone-mapping» was assembled in Picturenaut 2.12 using «derivative + hat 2» weighting, therefore the result is slightly different.
