(End credits, Excel Saga) Yes, today I have a very sad tale to share in my cyanography experiments. You remember last time, I shared this: Well, I have experimented further with inkjet photo paper, and made some very unpleasant discoveries along the way. The first is the streaking - without using a non-contact application method, I am not going to avoid it. The gel surface is just too fragile. So if I want to persist with this, it will be out with the air-brush. I somehow doubt I am going to find spray-cans of cyanotype sensitiser, after all. The second is in washing. Because there is no cellulose for the Prussian Blue to bond with, the washing inevitably destroys the image, meaning that you cannot preserve the image long-term. This also means that you end up including the un-exposed chemicals in the scan, which adds considerable grain and loss of contrast - especially in the high-tones of the inverted image.

ReplyDeleteThanks for this so very much.8 year old daughter going in for gastroscopy and colonoscopy tomorrow to check and confirm coeliac disease.good timing thanks.

Rob Masters thanks Rob.it will be a relief to finally know what is causing the immense stomach pain.her brothers have suggested that if a horror movie is auditioning soon she should apply for the part of the screaming girl- she lets us and the entire neighborhood know when its hurting.had to go the GF road about 12 years ago with my son who ended up with an allergy to gluten not coeliac disease.he has grown out of it . ill never forget the bread from then though, great toasted but not for sandwhiches for school!!!!!
ReplyDeleteOww!
ReplyDeleteAs far as bread goes, that has improved lots. The Helga's GF range is pretty good for commercial bakery stuff, but you should also check out Strange Grains for a treat. They win at the Royal Show against normal breads!
