Hello,

I have the Epson v750 and have had it for quite a while. All this time I've been using Epson Scan and get pretty decent results, until I started scanning some Kodachrome slides. I decided I wanted to install Silverfast for the Kodachrome feature, but I could not find the disk that shipped with the scanner. I looked for hours, and just last saturday I was cleaning out my basement (I have a box collection problem -can't seem to get rid of them) and found the original scanner box and sure enough I left the software inside the box.

Now that I have it installed and upgraded to 6.6 I have been trying to learn it. Just in a few days and from reading the silverfast forums I have picked up quite a bit. I have to say that it's a bit more complex than Epson Scan, but once I get used to it I can see that there is a lot more control.

So in my scanning sessions this morning I was working on a slide that I adjusted the overall color balance with the Global color correction tool and made the scan and it was good, but then I wanted to pull out some of the reds in the skin tones using the selective color correction tool. By the way I really fell like this is a powerful feature...

Anyway when I make my mask selections (4 total) and tone down the reds in the faces, everything looks good in the preview window, but when I make the scan and view it in photoshop or other programs it appears that whole entire image is effected by the toning down of the reds, rather than just the skin tones. You can see even the red graffiti is effected. What am I doing wrong? Thanks

I have included examples attached.

Hi there,

It is important to make sure that the application you are using to view your picture has a color management system, and even more important it is to make sure that it is correctly set to use the color profiles of your resulting files.
Bear in mind that Photoshop uses sRGB as working space and converts your pictures to that working space automatically by default.

Cheers

Thanks for the response. I am using Photoshop to view theses images, but unless I am mistaken regardless of the working profile I have set I feel my problem is independent of that.

In the above examples the scan were both viewed in Photoshop under the same working color settings. I used the selective color by making masks of the gils faces and legs only and dialed back the reds in their skin tones. However as you can see in the second image that the reds were dialed back globally, as if the selections did not stay within my masks. the first scan I did not use the color selection tool, it was a straight scan. the second scan was my result of attempting to use masking and the selective color tool. unsuccessfully.

Look closely at the color of the graffiti color in the before and after images, as well as the reddish street post in the background, and the bit of red building in the upper right area. Even the reds in the backpacks were affected. It appears that the reds were globally dialed back, but I did not include these in my selection - just the faces and legs - basically only the skintones.

Is there something I am doing wrong within Silverfast?

Thanks,

Joe

I have included some more scans that I hope further illustrates my issue. As you can see I made a selection mask within the color selection tool. I made an extreme adjustment within the mask that can clearly be seen.
Once I make the scan it's as if the color adjustment was made globally to the entire image. My adjustment did not stay within my mask.

I hope this helps illustrate the problem I am having.

Am I missing something very simple or do I have a serious problem?

Thanks,

Joe

here is my selection - a screen shot of the preview window as I am scanning

and here is the final scan:

In my scanning session this weekend I tried to further troubleshoot my problem. I reset the preferences again and when I made another scan I forgot to set the dpi slider to 6400 dpi. I discovered that my mask selections "took" at lower resolutions upon final scanning. I did a series of tests and discovered that 2400dpi is the last resolution before I start having the problems. Anything at 3200 dpi or above is where the trouble starts.

Any suggestions?

Hello there

I do not think you are doing anything wrong. This behavior is strange. I already send this case to the testing center where we will try to reproduce this issues.

Thanks for reporting
