I wonder if that could be added to the digital "reseau"?<br /><br />I'm working to recreate the silver gelatin process with dyed and milled grains of starch and a panchromatic emulsion. A quick shortcut might be to print your digital color mosaic onto a transparency using a high-resolution inkjet printer and use that as a mask over standard 4x5 black and white film. The film would be developed separately and reversal processed for a positive image. The mask would be reapplied after processing for viewing.<br /><br />I already have the chemistry for the reversal developing process perfected. I'm going to try printing the mosaic file to a transparency today to create the mask.<br /><br />Great work!<br /><br />Dondf99https://www.blogger.com/profile/08917205304201911313noreply@blogger.comtag:blogger.com,1999:blog-8768375296475349032.post-83552181678524282152018-01-31T07:08:15.670-06:002018-01-31T07:08:15.670-06:00This comment has been removed by the author.dabble778https://www.blogger.com/profile/18377299242405843664noreply@blogger.comtag:blogger.com,1999:blog-8768375296475349032.post-2361899211000011412016-10-30T08:54:19.845-05:002016-10-30T08:54:19.845-05:00Very well researched and implemented, well done!

Just one question - How do you drag the noise filter over the image? Do you mean create a layer above the target image? If so, how much opacity do you use? <br />Very many thanks.traklesshttps://www.blogger.com/profile/12445251314333371063noreply@blogger.comtag:blogger.com,1999:blog-8768375296475349032.post-90833285139581275432015-04-01T08:00:25.752-05:002015-04-01T08:00:25.752-05:00Mark, I really enjoyed this article, and your one ...Mark, I really enjoyed this article, and your one on color profiles. I thought they had lots of useful technical information, yet were still easy to follow. Color profiles were new to me, and I really enjoyed playing around with yours. The details about the science and colors of Autochrome Lumière helped me greatly as I was going about creating an iPhone app that turns regular photos into ones that looks like autochromes.

Yours is far and away the best I have come across. Really nice work. <br /><br />I implemented the noise filter as an overlay layer set to 50% grey. instead of a separate image Seems to work the same I think, and can make an action.<br /><br />Thanks!Ron Zacappahttps://www.blogger.com/profile/17453115091370368862noreply@blogger.comtag:blogger.com,1999:blog-8768375296475349032.post-49856414850639339992012-10-15T09:28:46.894-05:002012-10-15T09:28:46.894-05:00When you drag the filter over your target image, i...When you drag the filter over your target image, it gets automatically converted, and the primary colors will be correct. Or, you can assign the filter to the Autochrome profile first.Mark S.

But can I ask why you use red, gren and blue as the colours in your filer. The original colours in the potatoe starch filter, I believe, were, red-oragne, green and violet-blue. Surely those colours are a part of the special autochrome look.<br />Berit <br />Mark S. Abelnhttps://www.blogger.com/profile/06692448528819277158noreply@blogger.com
