    Another Comparison of the Howtek VS V850

    Again,
    The V850 is an excellent scanner for its price and you cannot go wrong with it. So I am not bashing it at all with these comparisons. Part of it is me getting better on the Howtek and also seeing what details I can get out of it for my better images.

    Both were scanned with a positive (slide) setting and converted with Colorneg in PS. The 3200dpi scan was scaled to 125% to the same size as the 4000dpi. (I did not change resolution from 3200 to 4000) I just set the magnification in PS to obtain the same size image on screen.

    Which one is the Howtek? Images are independent of dates.

    The second is sharper. What sharpening was done on both? Other adjustments?

    Steve, DId you ever check which (height) adjustment on the V850 film holder is the sharpest? Did you use it? I was surprised to find that it makes a difference that's pretty noticeable. I have no idea how the Howtek works. So I can;t help you there.

    Re: Another Comparison of the Howtek VS V850

    No processing of either image was done ( no sharpening, etc). I use the betterscanning adjustable holder and set the height some time ago after testing with a target. Bit images are wet mounted as well.

    I will post a later example of an image comparing V850 to Howtek.

    Adjusting height for V850 does make a difference.

    I'd suggest down-sampling the 4000 to 3200, instead of up-scaling the 3200 to 4000-- It's easier to throw information away than create it via interpolation.

    Also, don't label one as 4000 and one as 3200 PPI-- it makes it a bit more obvious which is which.

    Steven, I think another test that might give better results for comparison is to sharpen them for final review, especially the V850. I think the difference between the two scanners will narrow a lot. At least it did in my test between the same two units. After all, what it looks out of the scanner means little until the final sharpening is completed.

    I disagree on sharpening after scanning for comparison. The old saying crap in crap out. If your starting dole is degraded then all you are doing is masking issues and your final product will be sub par.

    I agree grat next pair I will do that. Although I can scan at 4000nor 3200 with either device.

    How do we know if the Howtek isn't automatically using a sharpening algorithm during the scan?

    Re: Another Comparison of the Howtek VS V850

    because I do not allow sharpening of any kind during scanning.
