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

a few hand tinted images

first ..   i probably have said this or explained my “terminology”
if i add colors by hand with paints &c i call the images hand painted, but if i
add the colors in photoshop i call them hand tinted.  these negatives
were made last fall, even before that sometime, but only processed recently.
i have had a real backlog of film to process, and luckily i have some D72 and Sumatranol C
all mixed up so it is pretty painless.

i’ve posted a few images from this group already ( last entry ) but here are a few more…

latest tinted images

i have been exposing film without processing it for about a year now.  i had about 20 or 25 rolls of assorted black/white and color
35mm and a couple of rolls of 120 film.  i also had about 30 sheets of assorted expired color and black and white 4×5 sheets.  i had wanted
to process the film months ago, but i’d cut my finger or something random so i couldn’t.  i am not someone who wears latex or nitril gloves when
i process film, i know i probably should, but when i process sheet film i can’t feel the sheets to pry them apart, and it makes it extra hard to shuffle
them in a tray.  i suppose if i used a hand tank, or still used hangers / tank, or a unicolor drum it wouldn’t matter much, but i put film in a tray and shuffling them from bottom to top, over and over again, first in water, then in developer for whatever amount of time i need to, and then in water and then in fix  and while i have attempted to use gloves, it just didn’t work well.  i always use them when i make cyanotypes, both coating and washing.  and i sometimes use them when i coat stuff with liquid emulsion. …  anyways  …

so i processed about 5 rolls of film and all 30 sheets on sunday.

they were all from last fall.  some local stuff, some things i made when i was out of town.

there was a regatta when i was in boston that saturday.  i don’t remember which day it was, i just remember it was sunny and cloudy and cold.
i parked by MIT and walked across the street with my box and made a handful of exposures.  then i drove to magazine beach and did the same sort
of thing.

cyclone negative cyanotype

a couple of days ago i was making some more cyanotypes i loaded up some contact frames with waxed negatives to see if i could get a better print than i did with my old coated paper some of those prints just didnt’ work out ..  and at the same time i found an old hand coated paper negative made with the cyclone #3 a while ago, that was just sitting on the tabletop.  i had cleaned up quite a bit a week or 2 ago:  i swept the floor;  i organized;  i put things away;  i stacked things;  i found things i hadn’t seen in a while.  the paper negative was a rediscovery, even though it wasn’t really lost.  it seems like it was coated on xerox paper, it is thin and durable.  not sure what emulsion is on it, maybe foma?  maybe my home-brew, not sure.  it has a nice contrast and look and i stuck it in the contact frame.  the waxed negatives took a ton of time before to expose, so i was banking on a day or 2 in the sun for all 3 of the cyanotypes.  it was a lot more diffuclt in late october because the sun is low, and it moves across the sky differently than before, so i had to really follow the sun around with the print frames. i did OK i suppose, but i was more in open shade than i was in the sun, and that is OK too.  the print is made from the same classic formula i coated the others with.  and after 2 days in the sun i washed it in water and added a little hydrogen peroxide to finish the development, and eventually i painted some areas of the print with dilute washing soda to give a yellowish hue to some areas. anyhow, its the kitchen table and window and chairs. not sure if i am going to add my own colors or leave it, the blue tones of cyanotypes are starting to grow on me.

 

classic, and blue

window table and chairs
classic cyanotype H2O2 to develop out faster as i always do, and a little washing soda to bleach and ad color

emulsive

i thought i posted a link to this but i guess it got away from me.

i was interviewed by emulsive.org a little while ago about film and emulsion and what i am up to. in case you don’t know about emulsive org what i am up to here is the link what’s emulsive.org ?  feel free to go there, its a pretty interesting site

well worth the click !

I am John Nanian and this is why I shoot film

photo illustration sort of, PS colored photo reconstruction

a while back i made some paper negative from hand made emulsion the negatives were more like a collage of things, images, textures, brush strokes. i decided to scan big and crop small and the image i retrieved from the paper was a sweet photograph of trees and a fencepost, but it always seemed to be missing something whenever i looked at it.  i put it aside for a good 6 months and looked at it a little bit more once i had distance from it

the other day i spent a handful of hours working on it.

i enlarged the canvas, i added colors ( which was i originally had hoped to do )

anyways, i worked and worked added, and subtracted and came up with this

it took hours, and it really still isn’t completely done, but it was fun making something that never really existed.

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.

new paper negatives from rockland AG+ emulsion

i’ve been coating thing with rockland emulsion off and on since i was told about it in 1986.  i had never made the investment in a tube of ag+.  i’ve always been on the poorer side of the street when it comes down to buying “stuff”  so i used the regular old non multigrade emulsion and then most recently someone gave me a tube of their extremely expired VC emulsion.  i am fond of making glass negatives and as you probably have read if you poked around this blog i like making ( or trying to make ! ) ferrotypes and glass positives, the ones made with silver gelatin emulsion, not collodion.  the emulsion that comes with the rockland tintype parlor is the ag+.  it was never enough for me in that tiny tube they provide, so i called bob, the guy at rockland and asked him if i could use the other emulsions ( regular, or vc or ? ) to make the tintypes and he said

“sure!  just coat it thicker because it doesn’t have as much silver as the ag+ ”

so that is what i did for a few years, coated things 2x.

now i am out of the other emulsions ( they sort of crapped out on me and turned useless seeing they were so old ) so i cracked open a bottle of the ag+ i bought on a whim IDK 4 or 5 years ago.  i chopped some out of the tube and double boilered it to melt it and i painted some on some butcher paper with a brush like i always do.  i have a puddle pusher but to be honest i never liked using it, so i never did.  the test negative i made came out terrible.  well, it wasn’t THAT bad, but it wasn’t as good as i had hoped.  i looked at the expiration date on the bottle and it wasn’t too out of date so i coated some more with the same bottle.  this time i used the puddle pusher. and boy am i glad i did !

most of the things i coat tend to have brush marks, sometimes it is good and i like that painterly feel, its something extra, a bonus but after i used the puddle pusher i think i might continue to use it and use it often !  the emulsion spread smooth and evenly, no marks, no problems.  i stuck a cut piece of 4×5  ( its actually 4 pieces of a little bigger than 35mm ) into my trusty old pentax K1000 and made an exposure out the window.  mundane scene, shadow, concrete steps, brick walk, plants.  it had contrast and texture and mid-day f16 iso 1 brightness, so i could figure out what the iso was of this now expired emulsion.

1 second hand held  then into the soup.

i have my caffneol in a big tupperware tub and i have a small one to scoop it out for trays, like a ladle …  seeing i don’t use much besides dektol and caffenol i sometimes have a bit of residual caked on coffee in the small tub.  usually it just dissolves with the caffenol i drain out of the big tub,  ..  i didn’t use the big tub this time.  i poured a little dektol into the container and added about 2x that amount of water.  the coffee dissolved nicely as i stired it a little bit.  the negative went in and i agitated it by flipping it, than by swirling the container and rocking it back and forth.  the image slowly appeared as expected in about 30-45 seconds ..  i developed to completion until i hit the 2 minute mark then into a water rinse then hardened fixer then i washed and hunt it to dry.  i didn’t make a contact print of the small paper negative but i scanned and inverted it.  no photoshop but sizing and inverting.  i have to say i was happy with what i saw.

i have a handful more papers all coated and ready to expose.

last group of cups and plates

i had a mini project with cups and saucers and bowls and plates.  all taken with a large camera on sheet film, processed in coffee and print developer ..  scanned and colors added by me ..  all sort of green and red, some better than others, all just fun  and playing around.

 

the bottom cups and handles were not taken at the same time, and just sort of fit together and noticed after the fact …

film processed in dektol and coffee

my last entry i mentioned i had finished exposing about 36 sheets of film.  it was more than that ..  4 bag-mags filled with a variety of tmx ( 100 ) tmy (400 ) and some mystery film that was bad enough that it never exposed.  maybe 10 sheets were as clear as unexposed film when it came out of the developer.  they were some of the first sheets i processed to test the developers.  i increased the times and added a little more dektol to my mix.  originally it was about 1:8 but i added so it was more like 1:6.

i hadn’t ever processed film in dektol before, only heard about it, and i have to say i was happy with the results.  i have to fine tune my dilutions and times but for the most part everything looked good.

i exposed in a variety of different lighting conditions, room light, weak window light, bright light and i exposed my film well.  sometimes developers need a little encouragement.  i go against convention.

here are 2 from my  39 sheets.

around 36 exposures

the last few days i have been using a graflex slr ( series D )  ..  just moments ago i exposed my last 12 exposure  ” bag mag ” full of what might be foma 2oo and tmx 100.  i loaded the film a month or so ago in anticipation of using it up fast.  i researched the notch codes seeing i didn’t recognize them, there are a lot of films that used that code and my best guess is that i loaded was fomapan200.  i found this very strange because i have have only bought fomapan200 film once in my life and the film box is unopened.  …  i am certain there are elves living nearby and they seem very interested in large format photography!  they have borrowed my light meters and cameras, film holders, glass plate holders, even film and dry plates in the past … usually the stuff is lost for about a year and they put things back with film i have never purchased.  so, i’m guessing this 30 sheets of fomapan200 was an exchange for the 30 sheets of tmy ( old 400 ) that went missing about a year ago.  it sounds almost like a modern brothers grimm story ( the shoemaker and the elves ), but that’s a post for a later date.

===

i loaded it in the bag mags ( 4 of them ) and made some controlled exposures to test my new film developer line which is DEKTOL 1:7 ( 4 mins )  then SUMATRA CAFFENOL C ( 5 mins ) then wash and fix normally.  if you read my posts here from time to time you will notice this seems familiar.  i usually do the same thing using ansco 130  ….  while it is sort of a new adventure, i am quite certain it will be just fine and i probably won’t even notice the difference.   i’ll post a few scans after i process the film.

3 paper negatives inverted

again with my paper negative tests

my dektol tests

my dektol + sumatra coffee developer split development tests

 

today i loaded film holders up and exposed the negatives in a more controlled environment.  i used a graflex series D camera so i cold focus and have a better idea of the exposure than a box camera …

well — sort of.

i also took a light meter reading, something i haven’t done in probably 2 years.  i wanted to know the unknowns and make exposures to see what was going on.   the first exposures was the middle one the images were all taken through a window — i pointed the meter out and set to iso 6.  i read about 6 seconds @ f4.  so i focused and stopped down a teeny bit and counted to 8 seconds  the 2nd exposure ( far left ) stopped down a quarter turn and about 20-22 seconds.  the 3rd exposure was a double exposure.  the first one stopped down more than 1/4 turn 20 seconds and then  wide open about 4 seconds.

not sure exactly what my fstops were because the lenshood blocks the numbers, i just know it wasn’ t f3.8 and it  wasn’t f 32 …

the prints were processed a the same exact time.  when the image appeared to come up i switched from dektol to caffenol then back in the dektol for a little boost in contrast i scanned them and inverted them and just barely adjusted the levels. my guess is the exposures and development were pretty much on target and the paper

hasn’t lost much contrast or gained much fog in 15 years since it is old and expired KODAK paper … i wish it didn’t all have kodak professional paper watermarking the back of the paper, or i would contact print the negatives into positive prints, the exposures look good for that too.

what did i mean by paper negative test?

i recently mentioned something about a paper negative test.

i suggested bracketing exposures and judging your negatives …

here, i have uploaded 3 images

 

the first

not photoshopped

cyclone #3 maybe f11

as the caption reads ..  it was taken with a cyclone #3 which i guess is around f11

light meter was set to iso 6 and it suggested  5 seconds

i count fast …  so i counted to 6.

the developer was 2 day old dektol, it is cold in my darkroom but the image appeared at around 20 sconds

so from previous experience, ( making prints in dektol ) i let it develop out fot at least 1 minute.

the negative looks ok.  there is a roundness to it because the lens has a big hot spot,

the edges are light the middle of the negative is dark.

the inversion ( #2 )

straight inversion, of a straight scan

f 11 6 seconds 15 year old polymax rc

the inverted positive looks OK

( kodak paper has writing on the back so i don’t bother contact printing kodak paper negatives )

the center of the image is light, the sides are dark, the background blown out.

this is expected.

today was an overcast day

this was about 145pm

the sky has a lot of blue light but where i was ..  was filtered a little so my meter gave me

a false reading.  for the deck where i was it was OK, the wood, the deck chairs and flower pots

seem to be OK exposed  …  if i was to multiple expose or burn in .. while making the exposure

i would under expose the sky and trees

with a little PS – love

it doesn’t look much different ..

i adjusted the woods a little bit, evened out a little bit the roundness and brightness / contrast

brightness, lightness burning in selective contrast

cyclone might have needed an extra few seconds for the woods
maybe burn in ..

 

next exposure will be tomorrow …

maybe i will try 6 seconds and in camera dodge out the sky

the developer might be a little easier to work with too …
