Ilford ortho plus in hc110- six or eight minutes?

TheGreatGasMaskMan · Nov 5, 2020

So I've got an Ilford Ortho plus ready to be developed, but the massive dev chart has two separate times for the film in hc110 at the same iso- 8 minutes and 6 minutes. Which one should I follow? Also note I probably won't be able to develop until saturday or sunday.

As Ilford Ortho is an orthocromatic film you can develop it with your inactinic light you use in your darkroom so you can use your eyes to judge how long to develop.

I developed Ilford Ortho plus 35mm for 9 min in HC-110E, which gives 6 min in HC-110B. Looks fine.

OK, so I just developed the film for six minutes, it's washing now but I did get some very high contrast negatives.

yes. Like most other ilford films, it's best to run this at 6 minutes in dilution b. here's some uncorrected scans from last year, probably from the roll that prompted this post.

The Massive Development Chart is a collection of anecdata, errant opinions and not-always-well-or-fully-transcribed manufacturers' data.

Instead, you should always start with the manufacturer's supplied data. You can find the Ortho+ one here. The two development times are for normal/ ISO contrast and for a higher contrast index (for technical uses etc).

To be fair to the MDC here it gives the same 6 mins as does Ilford for Ilfotec HC and warns that the 8 mins is not the maker's published time.

I agree, makers data should be the first port of call. However the problem with maker's times is that they are only for their own developers. So Ilford gives no times for non Ilford films with Ilfotec HC and Kodak gives no times for HC110 and non Kodak films.

Users of "hybrid" mixes of films and developers belonging to two different manufacturers have little choice but to use the MDC or if they are members of forums rely on the experience of users who use that combo. There aren't always such users and if there are their times may be right for them but not necessarily match what the person looking for the info needs

I think I did try looking that up back in the day, but hcc110 wasn’t listed

Ilfotec HC and HC-110 are near enough fully interchangeable, especially at dilution B/ 1+31 in non-replenished systems.

Didn’t know that

Save this, print it out, it is very useful.
