Ilford Formulas and Packed Chemicals. 14th edition errata.
I have just watched Peter Elgars Youtube video on mixing developers from raw chemicals.
He used 100g of sodium sulphite in ID11. Yesterday I was looking at Ilfords formula booklet and there is a whopping big error in the Ilford booklet. There are plenty of links on the internet to Ilfords book of formulas "Ilford Formulas and Packed Chemicals." http://www.darkroomdave.com/wp-conte...e-Dev-1953.pdf I was checking the ID11 formula and saw that on page fourteen in the 1953, 14th edition it has 200g of sodium sulphite instead of 100g. A couple of other editions that I found had the correct amount. I wonder how many people have gone adrift over almost seventy years of this error being out there? Cheers.

Big error on my behalf.
One formula is for anhydrous and the other is crystal. Hence one uses twice as much by weight. Sorry.

This is why I try not to post anything on the internet after 6pm Nat, as my brain has started shutting down for the night by then, and I'm starting to relax and eventually go to bed.
That's not to say that I don't post any boo-boo's in the daytime though - because I have been known to! Terry S |

Easily done, Nat, such things can happen when delving into information on a screen.
For whatever reason but probably my psyche and the era I am from, I am just not geared up to reading a screen in the same way as written text. I find it much more difficult to (a) follow screen text and (b) spot errors in it. The only kindle I really know about is that which my parents did with paper and wood before adding the coal Mike |

Just re-reading the PDF, I noticed the instructions, 'For press use' a few times. This meant using the solutions undiluted and at full strength.
What would the reason be for this? I can only think that it would make the development time (slightly?) quicker and / or maybe gave more contrast to a print? Can anyone confirm this or give another reason? Terry S |
