Minolta DiMage Scan Dual III Sample Scans and Comparisons

Minolta Scan Dual III versus the Nikon Coolscan IV

From the samples above, I can discern no difference in the resolution of the scans from the Minolta versus the Nikon Coolscan IV. There are obvious differences in color cast and exposure, but nothing is obvious about how much each scanner can resolve. I do give the edge to the Coolscan IV overall because it has Digital ICE and this is very valuable to have for productivity reasons in reducing the editing/spotting needs significantly. Both scans were made at default settings.


Dust Brush Samples

You do have to be a bit careful with the Dust Brush in certain cases because of what it may think is dust or blemishes to be covered up and what it should not as can be seen in the samples above. The left image is with the Dust Brush off and the on the right with the Dust Brust at its highest setting. In case you're wondering, this is a stone column from the Vancouver Art Gallery and it is suppose to have the horizontal lines going around the column at regular intervals.

 

Film Grain Resolvement

Above - sample scan from Fuji NPS 160 color negative film. Original, unedited scan at left and note the very high amount of grain found in what is regarded as an excellent professional color negative film. Sample at right is after Neat Image Pro has been applied, which results in a dramatic cleaning up of the film grain and noise. Canon EOS 3 and Canon 28-70mm f2.8 L equipment.

   

This sample shot is of my son too, but from about two-years ago and with Fuji Provia 100 slide film and my own Nikon F100, Nikon 35-70mm f2.8 and Nikon SB28 flash set for a minus 1.7 fill on Standard TTL mode. Different time but under similar overcast lighting conditions. Notice that the slide shot is almost grainless compared to the color negative shots; however, it still benefits from being processed with Neat Image Pro. Thanks to my friend Dennis for his work on processing these three sample images with his copy of Neat Image Pro, it sold me on the need for a powerful noise reduction application for scans or digital captures.


Comparing Scanned Film to Digital Capture

The following images were for personal curiosity and I offer them for you to review. I make no statement about this quick test being conclusive and if anything I would suspect the Minolta scanner to be a wee bit less than professional grade due to the results I found.


Nikon F100
Nikon 35-70mm f2.8
Manfrotto 190 tripod and 308 head
Fuji Provia 100F

No editing or sharpening applied except for resizing to match the D100 output.

Nikon D100
Nikon 35-70mm f2.8
Manfrotto 190 tripod and 308 head

RAW file processed through Photoshop's RAW convertor with no sharpening or editing applied.

Bronica SQ-Ai
Bronica PS 80mm f2.8
Manfrotto 190 tripod and 308 head
Fuji Provia 100F

No editing or sharpening applied except for resizing to match the D100 output.

To my eyes, I see that the D100 output is slightly superior to scanned 35mm film and scanned medium format is slightly superior to the D100 output, but not by too much in either case. I'm not going to make more of this because the Minolta scanner used to scan the pieces of film is an entry level device costing $500, 10x less than Minolta's best Pro Scan Multi, which I would expect to produce superior scans. So, I leave it at that without anymore comment because nothing can be concluded by this test at this point, just consider it a flight of fancy on my part. In case you're wondering, I cut a couple of frames from the medium format roll down to 35mm size and mounted them in some spare slide mounts for scanning. All exposures were the same and is based on a spot meter reading from my Sekonic 508 at a mid tone grey in the building, which was f9.5 at 1/30.
