My camera scanning experiments continue!
This is one of the last photos I scanned with my Nikon LS-8000ED before it died. Below are 100% crops of the images scanned with the Nikon and with the Olympus Pen-F to compare image quality.
This is from the Nikon scanner.
This is from the Olympus Pen-F, 20mp sensor in normal resolution mode.
This is from the Olympus Pen-F using the cameras 'sensor-shift' hi-resolution mode, resized down to the same size as the image from the scanner. The reason I did that is the Olympus hi-res mode makes images that look very soft unless sized down some. If you shoot JPEGs in this mode, the camera saves it as a 50mp file, but if you shoot RAW you get an 80m file. The JPEGs look sharp and the RAW files are not, and I think the need to resize it down a bit is why Olympus only gives a 50mp JPEG.
I shot these in RAW because I needed a 16bit file to allow me to adjust the tonality of the final image. As with scanning with a scanner, the camera scans are way too low in contrast and need tonal manipulation in Photoshop to make good B&W images.
As the examples show, the normal resolution camera mode has a little less detail and more noise than the image from the Nikon scanner. The hi-res camera mode image is slightly better in resolution than the image from the scanner, and has no noise (film grain is visible, of course, but no sensor noise).
So, it looks like the hi-res mode will give the best image quality, and actually slightly surpasses the Nikon scanner!
