Opinions about photo needed: slide scan

[Mustavio Fantastico]

Hello,

I was wondering if I could share this photo with the forum and receive some
opinions about the scan quality and color neutrality.
I used the standard Kodak IT8 calibration target that came with my scanner.


Camera: Nikon F80
Lens: Nikon 24mm f/2.8 D prime lens
Shutter speed: 1/180 s
Aperture: f11

Scanner: Plustek OpticFilm 7600i
Film: Kodak Elite Chrome 100
Software: SilverFast Ai Studio 6.6.2r4a
OS: Windows XP SP3


Settings:

*Resolution: 3600 dpi
*Scan Type: 48 Bit Color (not HDR)
*Embedded color profile: sRGB

*Gamma Gradation: 2.80
*Exposure: +1.30
*Original file type: Uncompressed 48 bit TIFF

*Compressed to JPEG at 100% quality setting.
*Resized to 1280 x 870 resolution with Lanczos filter.

*File size: 1.6 mb

The quality of the scan and the colors look nice and neutral to my eyes.
The colors appear exactly as scanned. I have not manipulated the photo.
Only problem is that the resizing causes some loss of sharpness.
On my computer the uncompressed TIFF file when viewed at my screen resolution of 1280 x 1024,
looks sharper.

But I would like to know what others think, and if there is anything I should change or improve.

Hi there

Only problem is that the resizing causes some loss of sharpness.
On my computer the uncompressed TIFF file when viewed at my screen resolution of 1280 x 1024,
looks sharper.

Well it is normal during the resizing some loss of quality, this might be reflected on sharpness, details or colors also compressing from tiff to jpg will show some degradation.

Cheers

Was there any detail in the blacks and the highlights (mostly building walls) on the original ? Check the Black and White point settings.
You might try to expand the dynamic range with Multi Exposure if available for your scanner or use Photoshop manually.

Yes, there were more details in the original.
And I already used Multi-Exposure. Forgot to mention it in my original post. I always have it enabled.
The scan does not capture the amount of dynamic range I see when I hold the slide shot
up against a light source and view it directly with my own eyes.
I don't use Photoshop. I use another program.
And increasing the light level of the shadows makes dark parts brighter but also has a tendency
to turn them purple. Raising shadows for example results in the guy's black jacket looking purple.
I am disappointed with the dynamic range of my scanner. Dmax is 3.6.
Even when raising Gamma Gradation to 2.8 and using an exposure compensation of +1.50,
my scans still do not look like the original slides in terms of dynamics.
