happy problem

[raytoei]

my minolta 5400 scanner couldn't start,
it could be a power supply problem, or it
could be something else.

in a fit of insanity, i decided that
i would never pay so much for a
electrical device especially when it
was eight years old.

i also told myself that it would be
better to buy several cheap and good scanners
than buy one good but expensive scanners.

so i started accumulating the next best minolta scanner
the scan dual IV, with a max resolution of 3200 and
a dmax of 4.8. the Scan Dual IV was like 1/2 - 1/3 the
price of the Scan Elite 5400.

One week late, I accumulated about four Scan Dual IV.

Today, I tried a spare power ac adapter for the dead
scanner, and lo and behold, it became alive.

So, i am going to be stuck with four minolta scan dual iv
scanners, will probably arrive in 2 weeks. It will be very interesting
to see how to compare the 5400 vs the 3200 assuming a
similar DPI.

with 4 more PCs, can scan 5 negatives at 1 go! only choke point is operator speed ;p

just a quick post on some image comparison....
between Epson V700 with AntiNewtonRing Glass,
Minolta Dimage Scan Elite 5400 and the Minolta Scan
Dual 3200 (in a fit of madness, I ordered 4 SD3200,
all between 100 - 150usd, with the logic that not all
will survive the journey to Singapore, postage is expensive,
I am just reviewing the first one that arrived yesterday).

All captured on 3200 dpi,
All 8-bit greyscale
Brightness either 0.5 in vuescan
or auto in Epson Scan.
Sharpening is Med by default in Epsonscan,
in Vuescan I turned on sharpening.

First of all, the Epson V700 with ANR glass,

Next is the Minolta 3200 with Sharpening turned on.

The next example is the Scan Elite 5400 with Sharpening turned on.

Lastly, I decided that sharpening was too sharp, I tested to test
the Minolta Scan Elite 5400 with Sharpening turned off.

Conclusion:

So far, the winner seem to be the Minolta Scan Elite 5400, even
without sharpening, the images it produces are very sharp,
down to the emulsion pattern. Next is the Minolta Scan Dual 3200,
the images aren't as fine as the 5400, but neither does it hurt my
eyes when I stare as the picture.

I've been reading about this new technique that I'm trying to apply to my scans. It's called super resolution, and involves combining multiple images to upscale the resolution. The result is bigger files and increase in details. One software I know of that is capable of this is Photoacute, but I haven't had the chance to try it yet.

Google super resolution for lots more info...

Perhaps with 4 scanners, you can put them to good use hehe

I tried this, and it works very well. The improvement in resolution is really surprising. The only issue is -- it is too tiring to do this for every scan, but good to know this option exists.

Raytoei,

Sorry to disturb, can I know what is the film used in the scanning sample? Thanks

 

[raytoei]

according to my notes:

Yashica T4 with Kodak Tri-x film.
Developed in D76 solution for 5mins 30sec @30c.

cheers!
