Hi people,

I have a problem. I am a 56 Yr old College student and getting back into Photography, My school used Kodak HC 110.

I got some Kentmere 400 ISO film and it does not show any thing about HC 110?

I know its made by Ilfprd but I need to develop with what the school has???

I am going to try and use the times for Astra EDU Ultra 400 and I have been using the Ilford HP5+ which

works great, I just did not like the Astra film, grain is too big even developing at a Temp of 64 degrees F

wanted to use a different film annd I liked Ilford but I did not like what the school gave us.

Astra EDU Ultra 400 ISO. Does anyone have an idea on time to develop this film Using HC-110 - B.

I have looked on Ilford's Site and Kentmere's plus several others including this one.

Your help in this topic will be greatly needed.

Thanks

Kentmere 400 needs 8 minutes in Ilford Ilfotec HC at 1+31 (according to the chart on this site), use the same time with HC-110 B (ilfotec HC at 1+31 is very similar to HC-110 B)

You should probably start a new thread for this question.

Lodima (Amidol spelt backwards) is a new silver chloride paper designed as a replacement for Azo.
The technical information for Azo might still be useful for anyone who wants to try Lodima.

I wonder who's manufacturing the paper? Someplace in Hungary? Czech Republic?
There are at least two candidates: Fujifilm and Foma Bohemia

They are both RC papers, though.
Well this is odd...I don't know, really...interesting to see what's going on though.

I used a method I'd read about in Les McClean's book "Creative Darkroom Photography" which recommended Tri-x in D-76 1:40 (!) stood in a bath for five hours. I have to think the dilution he recommends was a misprint. Needless to say the experiment was an utter failure, yielding blank plastic. I've never since considered stand development, but I do read about others doing it and wonder where the idea comes from and why people do it. Les McClean says he got his method from an old newsman, which makes me assume its an older method from another era. There's something quaint and mysterious about it, which might account for its popularity in internet discussion groups: people love lost, secret methods known only to old newsmen. But is there any real reason to do stand development nowadays?
The idea behind stand development is to have basically no movement of developer or development by-products. On a plate that is perfectly horizontal, the byproducts of development remain where they are formed. They thus retard development in proportion to the density of development, so there is a considerable capacity for compression of extreme contrasts. Highly dilute developer is used, and development is extended for hours.

There is a thread on APUG about it:

The 1:40 dilution is not a misprint.

Interesting, although D-76/ID-11 seems to be an odd choice because it is considered to be a low to moderate energy developer, even at full strength.

Instead, use dilute developers and agitate once per minute properly.
Perhaps you should visit flickr and do a search on "stand". Pretty sure there are virtually no glass plates and no streaking. Here is an example of 2hr stand developing in Rodinal. http://www.flickr.com/photos/peterbcart ... 674774965/

I'm not sure why you are so concerned about perpetuating a myth that doesn't exist.

For me there are two reasons I tend to stand develop.

1) Although I normally use a pyro to compress the dynamic range of the negitive, pyro's tend not to push very well (none that I have tried). I expose for the shadows (alot) and rely on the pyro to control the highs. I pull the ei more often than not. When pushing, stand development has the same result. You will get what seems to be a thin negative, when done properly. When you use high contrast papers, the result is an amazing amount of captured details in the shadows and the highlights. When scanning, the DMAX is lower and details can easily be sucked out without loss of shadows or highlights.

2) It tends to control the grain better. http://www.flickr.com/photos/peterbcart ... 674774965/ was taken with 35mm hp5+ at ei 3200. Considering it was developed in Rodinal, it has amazing low grain.

My main reason for doing stand is #1.

There is a definite risk of streaking when the film is not a glass plate held perfectly horizontally.

Risk is a strong word and horizontal placement has nothing to do with it.

When the bromide is released during development, on some films it can re-attach and produce streaks. This my happen more on some films then others and the same with developers. This has nothing to do with horizontal placement and is easily resolved by "semi-stand" development. For stand development for an hour or more, I agitate at thirty minute intervals. Otherwise, I go at halfway.

Stand development was used in Germany in particular, and from what I have read, was already obsolete by the turn of the 20th century. It was used to develop glass plates; the plates were placed in a perfectly horizontal position in the solution. That way, there is no movement of the development by-products away from where they form. These by-products are heavier than the developer solution and tend to fall along the surface of the emulsion, where they impede development. They do not 'reattach" themselves to the film or developer. They are expelled from the emulsion's surface in proportion to the intensity of exposure. Sometimes they simply cause an extremely noticeable line around dark areas, producing a rather unsightly effect:

I found the attached images on the internet.

I believe these are called "Mackie lines". The other shows streaks.

I believe that the stand development technique works best with glycin developers, and since glycin is not used in most commercial products available today, it is probably not worth the trouble.

http://www.jackspcs.com/glycindv.htm

One such formula is Hübl Paste:

Hot water (50-55 C), 500ml
Sodium sulfite (anhydrous), 165g
Glycin, 135g
mix well and add gradually
Potassium or sodium carbonate, either crystals, 625 g or anhydrous, 560 g
Water to make 1 litre
