    Torchon Review by Mark
    on: March 11, 2022 at 8:54 pm

    Nice thing about digital is if you got the files, you can just print new ones if the prints start looking shabby.

    Hahnemühle Torchon is one of their better, if not best paper, for resistance to flaking. Hahnemühle has some beautiful finish watercolor papers, but if you handle them, they will flake off specks in the blacks. I will have to scan some old test prints to show it. If you print on these rough papers, you had better put them behind glass ASAP.

    Forget the optical brightener worries. It makes the base whiter. The paper will just go back to normal if and when the optical brighteners disappear. It is not like they will fade your photo. It is not really that big a deal.

    What does make a big deal is if you use dye-based inkjet. Pigment inkjet is very archival, dye based is pretty poor. Fuji’s Cystal Archive is almost as good as the lowest grade pigment inkjet in fade resistance. The old Kodak C paper was poor. Dye transfers varies as to when they were made, as the dye formula changed. The 1950’s were poor for light fastness. 1970’s a little better. By the 80’s / 90’s they were getting pretty good, but still not as good as what we got now.

    I’ve done a huge amount of sun fade testing over the last 12 years. And it is not only with prints. I fade test many other areas from computer media to film.

    In subdued light a pigment-based inkjet should last decade/s with little fading. This Epson pigment inkjet was put in the sun for a year with no ill results.

    Put it in the sun for 2 years and you will see ‘some’ fading.

    Here are some old posts on inkjet.

    I had a full fade test website at Tumblr, along with 47 other websites. But Tumblr pulled the plug on them all in 2019 and deleted everything. It is just sickening all the lost time and work from internet censorship. And even with special collection libraries; they trash works of art if they decide to put you on the shit list.

    Here is an example of a 1955 dye transfer fade test after 6 months in the sun. Right now I’m doing a fade test on carbro prints from the 50’s.

    Here is an autochrome fade test with 2.5 months of sun.

    Too bad sun fades some of the reds or it does a good job removing the fog on the autochrome!

    I will have to recreate the fade test website. But as I mentioned, just sick of all the loss from the internet. I hate doing work twice.

    Hello to all!

    I found this forum by coming across Mark D. Segal’s article on camera scanning. I looked at his earlier article on the same topic he had written way back when. This was before his copy stand days, when he was using a tripod. What a difference he had made in refining his setup…he really breastfeeds it all to you!

    I’m just getting started with camera scanning. I’m a photographer and archivist and also work with audio and cine’ film. I’ve been doing scanning for years (sheetfed) / decades (flatbed), sometimes making 20K -30K sheetfed scans year along with a thousand or two flatbed scans of paper.

    A while back I tested a camera scan of a chrome. This was before I read Mark’s article. I had been hearing about camera scanning on forums, so gave it a try on my copy stand.

    This was shot with an old Fuji 16mp camera. Heavily cropped, not anywhere near macro. But it clued me into the possibilities of camera scanning encouraging me to study camera scanning further.

     

     

    I’m just working slow and testing things as I go. It is not like the old days when money was not an issue, and I could just throw money at a thing to learn. Nowadays, budget is tight, so try to avoid the school of hard knocks with the education.

    I had heard that scanners have different focus points for film, so first test I did was to compare my V500 to the V600 scanner.  (Still need to try my V700 scanner.)  The scanners don’t resolve all that much in fine detail when you get down to it. Kinda sad.

    Here are a few of the tests looking for focus points on the V500 using the area in red.

    6400 dpi scan is at glass level using an Epson V500 scanner.

     

    Resolution target was raised .225mm above the scanner glass using a Epson V500 scanner at 6400 dpi.

    …I kept trying different focus points. I won’t post them all here, but they went up to 3mm above the glass in various increments.

    Resolution target was raised 2mm above the scanner glass using a Epson V500 scanner at 6400 dpi.

    Looks like the V500 did best at glass level. I still need to crop up the V600 scans. It is a harder scanner to use than the V500 with trying to do on glass scans with no holders. (But there may be a trick to it…dunno?) The Fuji 16mm camera was not that impressive. Still need to post process the photos of that. From rough quick sees, with the macro lens and a 11mm tube, it looks like the Fuji 16mm compares somewhat to the Epson V55. (But don’t hold me to it…I said quick look.)

    Now, if you ever wondered how well a sheetfed scanner works, here is an old post I did on it comparing sheetfed scanner to copy stand to flatbed scanner.
