  1. Re: Where are the great shots? Am I a cynicist or a realist?

    Over the years I've often come back to this quote concerning Archery. Taking these pursuits as a form of self-cultivation, we could easily substitute the word archer with photographer.

  4. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    I don't think it's not a software problem. The scanner worked fine while I was doing tests. Then it just stopped working after no changes were made to anything. It can only be a mechanical or...
  5. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    The scanner makes the unpleasant sound as soon as the power switch is turned on. It's not a software issue as far as I know.

    I guess I need to open it up and see if there's anything obviously...
  6. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    Thanks Pere. I checked and reset those switches several times.

    I was making test scans all day: at a certain point the machine just stopped working.

    I presume that some part needs replacement.
  7. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    Funny - My Epson V700 just died. I hadn't used it much lately until making these tests, but it now puts out a funny noise and the red lights flash.

    No good deed goes unpunished I guess :rolleyes:...
  8. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    The Stouffer Transmission Step Wedge has 21 steps in "increments of .15". Each step is a half f/stop.

    If my math is correct, 21 steps amounts to a density range of 10.5 f/stops. 2 exp(10.5) =...
  9. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    After applying a Gamma 2.2 correction to the VueScan raw file (not adjusted to level 3, the original scan), it seems that the VueScan values are somewhat more equi-distant than the Epson values. I...

    For the record this was a Stouffer Transmission Step Wedge sized 4x5 inches. According to the packaging it has 21 steps in "increments of .15".

  12. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    I guessed that scanning it as a slide, IE a positive, would be simpler and therefore better, since no reversal step is included in the process.
  13. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    I have added a link the original raw VueScan scan file with no gamma adjustment to the same post where I posted the others.

    All those files are down-sized to a width of 1200 pixels.

    The prints would not look all the same. Some would be similar to the correct exposure.

    We would see a corresponding difference in the density of the resulting images.

  22. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    Eureka ! That works nicely.

    Given what Ted has pointed out, I guess it shouldn't be too surprising that the VueScan raw file and the Epson Scan file made with no color corrections don't match...
  23. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    This isn't because you're using a PC, it's because you're scanning a transparency. If I scan a transparency on my Mac I get the same black image once I move the right slider too far to the right.

    Those options appear if we scan transparencies. And as promised, the scanner stepper motor runs slower when we set them to a higher value.

  29. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    In these tests I have made low-res scans of a positive (a recent print) because it's easy to spot a faithful rendition when we can see the original. It's easy to tell that the 3 scans made with no...

    Yes, that's one of the points made in the article: I don't use VueScan. It's a rather long article, so that may have escaped people's attention if they only had time to skim it, or skim this thread...

    Even if you set it to 0, the brightness of the image changes as you vary the cropping.
  35. Re: Update to Epson scanning article: how to bypass all tonal adjustments

    The VueScan raw file is an output file type, like JPG, PNG, etc. It is a TIFF embedded in a file, with some additional header information, if I understand correctly. In that sense it is like the raw...
