Development-PaperTest+Book Demo

I bought a 70GSM translucent tracing paper and a free texture paper (about 50GSM) for experiments.

Thank you RCA's A2 newspaper is very useful. I can directly cut the color block and stick it on the paper, and you can see the transparent color of each layer. I chose color blocks and lines, and found that the transparency of the 70GSM tracing paper is too high.

Another kind of paper was cut into A5 to make a small instantbook in order to realize my idea of ​​another book-demo. the result is very satisfying to me.

These are the paper models of peoples drawings combinations, even though it’s 2D this was necessary to see what outcome is possible and thinking how to incorporate this in further practice... Each piece represent different person and have been put together regard to the personality...

Rose. She’s just a quick character study. I don’t have a story for her, yet. When I drew her, she insisted something out of frame was far more interesting than making eye contact. #artisttradingcards #watercolour #fairy #rose #ottawaart #ottawaartist #papertest https://www.instagram.com/p/By43Pjgjezk/?igshid=7ewq7hgergnz

Testing the new paper! Love it so much!!! It thin, but it can carry few layers with watercolor. It is so nice to carry it around for doodling on trip. #watercolor #mermaid #doodle #papertest

Messing around with paper again... this time on @strathmoreart Vision Watercolour paper. Inked with @tombowusa Fudenosuke pen and coloured with Tombow Brush Pens and the blending palette. Paper texture has never really mattered to me, to be truthful, and I always thought that watercolour paper wasn't really the best for what I needed I always chose sketch pads or copy paper because I always ink everything and colour digitally. This stuff turned out awesome. Using the blending palette is like using Watercolours, so it was a natural fit. The way the paper treats the ink was gorgeous and it kept the initial colour of the ink very well. Still trying to figure out a name for this guy, but also wondering if you guys would like to see him on stickers, prints, or other things? I would include the stickers with physical commissions, which I always have open... let me know what you think! #senorrandom #torontoartists #tombow #strathmore #heartguy #fighter #papertest (at Toronto, Ontario) https://www.instagram.com/p/Bpzut08Fhjl/?utm_source=ig_tumblr_share&igshid=1x79wg2ydy0v8

Homo Anonymous in Print

Three days in a row, sounds like start of a good song. It was yesterday I heard music in my ears while working in the darkroom. Getting a good result for the first time after nine hours of trial and error making a wet print.

I started last Sunday, making as much mistakes as possible while having my eye on the troubleshooting list. I discovered some flaws in my workflow. Last monday I changed some things I the workflow, for example focusing one making one good print instead of ten different prints without any good results. Again having my eye on the troubleshootlist. It turned out the paper was bad, I ran a papertest and it came out all black. So I did throw away the box (placed it in the drawer, maybe I can use it some day for another purpose).

Yesterday I ran a couple of more tests: another papertest of a new box (opened a long time ago) it came out white, so that’s a good thing. I also ran a safelight test, by placing objects on a piece of paper, after replacing the bulb with a new one with some sort of plastic ring on it.

A safelight bulb is never completely painted towards the base of the bulb. This test worked great the safelight was now completely safe.

So now it was time to make the best possible print to my ability. Making good notes by every step. Something I need to learn to be consequent about it so I can reproduce prints afterwards and learn my process.

Turned out I needed 10 steps (read: ten times printing ± 3 hours of work) to get a print that was very fulfilling. 00) Installing a timer for controlling the enlarger 01) Paper test in complete darkness 02) Paper Safelight test 03) Lightening time test, setting a base for paper en enlarger 04) Testprint with the best time out of the previous test 05) After controlling the testprint, make another lightening test using a 2.5 contrast filter. 06) Testprint with lighteningtime found in previous test. 07) ‘Shiny side up’ of the negative turned out to be bullshit, after discovering the print was a mirror image. 08-10) Making contrast adjustments

The key to a good print is controlling contrast. This will take a lot of testing and practising. Overall I love the process of making a good print out of my 4x5” negatives. So I can work completely analogue now.
