Crop from Nikon Coolscan IV - Unedited

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. |

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. |

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. |

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.
