sun print

i realized last week the emulsion is sensitive enough to print through the photo paper if reversed.

this was printed in full sun for about 1 hour

a few prints

this first prints were made by a digital overhead transparancy at my local copy shop
originally it was a digital files taken in a snow storm at a local park.  one was taken on jamestown island ( the windmill )
a few weeks ago.  all 3 of them were made using expired photo paper behind the digital negative and left in the sun by a window
for a few days.  i scanned the images and used levels a little bit as i do every scan

chloro bromide emulsion #2

its been a while since i made the emulsion i wrote about here
but that isn’t to say it hasnt been on my mind since a year ago january.  i’ve  been distracted with life and trying to finish off all my film, and making more sun and retina
and cyanotype prints.  but this morning i decided to make some more go-juice.

i dont’ really have a recipe that  belongs to someone else i follow but i mix and match hoping it will work,  this time around here is what i am doing:

 

120cc water
4g iodized salt
12g potassium bromide
1cc of watered down D72 !
20g hard bloom gelatin

( my last batch was knox gelatin, it worked OK for a little while but eventually the gelatin broke down and made a mess )

i heated up the water and added and stirred all the ingredients so they are mixed and dissolved well.  the water i put in a cheap metal pot
and i heated it up on the single burner i use to roast my coffee.  when everything got dissolved and well mixed i took the salted gelatin out of the pot
it’s now sitting on the enlarger table.  i’ll go back down in a little bit and re-heat it to liquid again as i mix the silver nitrate and water together.

next is the silver nitrate i put on an apron, gloves and EYE GOGGLES and measured 32g silver nitrate and 120cc warm water.
and mixed this until it was completely dissolved.

with the safelight on and the salted gelatin warm i stirred like mad and slowly mixed the silver nitrate into the gelatin.
eyesight is nothing to play with, and silver nitrate will blind you without a second thought.  always use eye protection !

anyways i dribbled and mixed the silver nitrate in there and the whole mixture turned white.
i’ll use this as a paper emulsion, so i won’t bother to wash it.  i put the ball jar into a locking air tight container
and then in a black paper bag and stuck it in the refrigerator to set.

i have no clue if it will work or not, i’m looking forward to finding out soon !

in a few days i will coat some paper and expose it and post my results

 

OK it is the next day and i really couldn’t help myself …

the emulsion was put in one of those hinged jars that have a rubber seal, like the stuff you might
have on your counter with coffee beans or sugar or whatever ..  the bell jar was inside that ..  the whole thing in
a black bag photo paper usually comes in when it is in the box ..  i didn’t really trust that the jar i put it in was light proof
so i bagged it when i put it in the little fridge.

the moment of truth ..

i brought the jar to the red room and opened it, and it set ( WHEW ! ) i always worry i didn’t put enough gelatin in there
and it would be a watery mess.  it was emulsion alright

i scooped a little out and warmed / melted it and painted it onto some card stock.

its drying now …  but when its dry i will rip it in half and hide half of it.  i’ll put something on the card and turn the lights on
and make a photogram in some dektol and see if this stuff works.  after that i will put s cut piece in my K1000 and make a test strip to determine
exposure times and iso’s.  and easy way i usually do is f 11, block the lens off and make a series of 1 second exposures. and develop the strip to see what happens.

 

OK …

well i realized the watered down 1cc ( if that ) of liquid i added at the end was dektol, not hypo
i hate amber bottles !

i did my first 2 tests and coated some more paper.

the photogram i made i counted to 6 with the room light on and it made a killer photogram.
i handheld a slip inside a camera f2 $ 15 seconds and it looks to be about right.

they are still washing and more paper is drying so i can’t really say for sure what everything is.
i know if in the camera ends up being too tedious i make enough photograms and sun prints it won’t be an issue using this home brew emulsion

recent cyanotypes

just made a handful of cyanotypes lately using paper coated and left in a light safe in a humid basement for the last 7 or 8 months.  the paper was not the best but it worked (sort of) made some photograms ( some i watercolored ) i made a contact print with a waxed rubbing and tinted it in photoshop and i also converted some digital images into black and white negatives on xerox paper and waxed and printed them.

i have some more negatives to print and cyanotype paper to use up before i mix new.

double coating paper

i dug into a 1 kg jar of foma emulsion the other day.  i know i can make my own but i have this still on hand so i might as well just use it until i run out.  coating paper and glass and metal with it will be great practice for when i don’t want to waste stuff i spend time making on my own.  so i took a few of the large sheets of xerox paper i had already coated.  i took 1 of them and with the lights on i exposed it in developer to show how poorly i coat.  it wasn’t that poor, it just wasn’t very good,  no it was pretty bad … it was  a lot of grey, only 1 area of black.  i’ve been coating things for years and this is the first time i did this …  that’s ok.  im a noob, even after 30 years.  i used a coating rod the last time, and a brush, but still things weren’t as good as i had hoped.  with denise ross’s book in hand, or at least in my mind
( if you haven’t gotten her blurb book and you like coating things, and making things, it is worth every penny you pay for it:  http://www.blurb.com/b/6465389-the-light-farm  ..)  i never thought about paper grain ( now i do )  i never thought about wet coating ( now i do ).

i took the remaining 2 sheets of paper and cut them into 4×5 pieces and soaked them in cold water.  this isn’t really what denise did in the book but that’s ok.  it is easy to tell which side is emulsion and which isn’t ( the emulsion side is slippery ).  i took my squeegee and removed the water from the prints 1 at a time and with warm emulsion i re-coated each piece of paper.  i looked at each piece in the safelight and they looked coated ( i guess they always do )  but coating 4×5 pieces was always easy for me, so my fingers are crossed that the 2nd emulsion layer took.  i’ve coated cyanotypes 2x, and other stuff 2x but never wet.  i’m hoping denise’s invention and my twisting it for my own needs took.

i also took some sheets of regular paper and coated that stuff too.  1 sheet folds and cuts into 18 4x5s.  i’m still trying to figure out what it is.  i did a little research and it seems to be “virgin” butcher paper.  uline sells it cut into the same size sheets or on a big roll.  alex art supply also sells something similar to it.  in both cases it isn’t the same weight (thickness) but it seems similar enough that when i runout at least i will have something to buy.  smooth finish paper i like best for coating.  nyways, i cut 1 sheet up soaked and squeegeed it and coated 14 pieces.  they are hanging on the line.

a few photograms, with hand made emulsion

i love making photograms.  they only take a second, and they are a blast.

for some things, thin paper seems best

its been a week or two since i mixed up the emulsion,and started playing with it.  i’ve come to the conclusion that this emulsion works likes thin smooth paper like the butcher paper that i use thick velum paper i sometimes use for bottled emulsion paper negatives and cyanotypes don’t really provide a good negative for me with this emulsion, maybe it is because i don’t use photo grade gelatin, maybe its because i didn’t coat the paper with gelatin first like a sub layer so the emulsion sits too far in the paper, i’m not sure what it is, but the next coating sesison i do, i will coat more thin paper.  i do have some thicker sheets coated, i actually double coated everything to give me better contrast.  i get OK contrast but some of the images just don’t work well.  i have some that worked well, but my success rate is not very high with thick paper.

ive been doing small test sheets, in a 35mm camera to get an idea of iso, and how the images look.  the emulsion is starting to get white and black speckles in it  so i have to use it up before it goes bad, and then i will probably use up my bottled stash and make some more fresh emulsion soon after.

a few photographs from my efforts

a few more paper negatives

as i wait for single coated paper to flatten out so i can coat them a 2nd time  i have a few paper negatives exposed the last few days in a cyclone, and processed yesterday.

i scanned 8 and have worked on a few ..  i added color sometimes, or not they lean off center.
