I made some tests with my 3d printed 4x5 on some RC paper. Coming very soon.

I gave my Calumet 4x5 a go today, and it worked! Except…. I’ve read that the Ilford paper I decided to use was 6 ISO, but it’s definitely 3 ISO, or my developing time is too long. But when you’re developing for 60 seconds, it’s a bit hard to gauge. On the next run, I’m going to meter for 3 ISO and shoot that, and see what it gives me. So far though, I REALLY like the results. The sharpness looks pretty nice on RC paper, and once I get the exposure times figured out, I think it’ll look even better. I’m still working on how to clean up the prints, as the Dektol developer I’m using tends to leave little bits on the prints (as it comes powdered). I’m thinking I may switch to a liquid developer. We’ll see as time goes on, for now the experimentation will keep going.

Took the Calumet out this afternoon to do some more test shots. Tried metering for 3 ISO this time, and I'm going to keep the developer bath the same. Unfortunately I've got to develop it all tomorrow, so I'll see how well it worked then.

Test shots, round two. The second test shots with the Calumet and RC paper positives went about the same as the first set, with some success and some problems. Just as with last time, only three of the four photos really worked. With the previous set, one was too under exposed, and this time, one was too over exposed! Turns out the paper is somewhere between 3 ISO and 6 ISO. Plus, on this round, I even forgot one problem with large format cameras: the drop in light when you focus on a closer subject due to the increased distance between the lens and the film. I’m not sure what the ratio is, so I’ll have to do some research on it. Tonight I’m hopefully going to do four more test shots, this time indoors with a lamp. Hopefully this way I’ll be able to finally get all this sorted out.

The Constitutions of Inkjet Photo Paper

There are hundreds of brands of ink jet printing paper on the market , it seems like that products are multifarious. although the publicity of photo paper manufacturers is dazzling, but the production mode and process determines the fundamental difference between paper properties.

In general, inkjet photo paper only can be divided into three types: ordinary high glossy photo paper (referred to high glossy), RC (referred to microporous waterproof photo paper) and cast coated paper.

 Before talking about inkjet photo paper, firstly we should introduce two kinds of substrate preparation of paper: base paper and RC base paper. In the generation of black and white photos photo paper are mostly constituted by base paper + photosensitive coating base paper. The differences between base paper and ordinary paper is that base paper is all made in natural wood pulp fiber in order to ensure the smooth paper and strong. Short fiber comes from wood pulp paper and is completely nature but the cost is very high.

 But the base paper is not waterproof, in order to solve this problem, when it comes to the color photo, mostly composed of RC + color photographic paper base coating. RC is the abbreviation of Resin Coated, which means the resin coating or resin film, is a layer of resin film on both sides of paper. Thus solve the problem of waterproof and stiffness of the base paper. Currently, the laminating resin was mainly PE (polyethylene), usually the paper that produced with RC paper base called RC photographic paper.
