TX400 and HC110

[LisaU]

Thanks Matt and Larry. I'll try this tomorrow. It's driving me crazy and I have a few jobs that are waiting for me to figure this out. I'm sorry Henry for overrunning your thread.

Thanks Fred. I'll try that for sure.

I usually mix up the stock solution and put it in smaller bottles since I dev. many rolls at this time of the year and it's the easiest. But, I think I will start using it from syrup like many suggest.

I'm thinking it may be the dev itself since it's the only variable that I can't control. This only started to happen around September and then I started adjusting to the problem by extending another 2 minutes of dev time. Because there is only one store on island and I get all my HC110 there, could it maybe be a case of dev. that got left out in the sun or maybe it's really old stock? I ordered some online so I'll see if that makes a difference. I'm just worried that I'll get a "good" bottle or something and then dev. 2 min over and get crazy contrast.

Hi Lisa,

If your bottle of syrup is sunshine yellow or slightly darker orangish color, it is most likely okay. HC110 syrup keeps a very long time. I have some that is 3 yrs old that works fine but an orangish color. Diluted (stock) solutions have a much shorter shelf life. Check the Kodak data sheet and I seem to remember that 2 months is about it. I believe this is why most of us dilute from syrup.

Good Luck!

Fred, my bottle was bright yellow and so was the stock solution when we mixed it to working strength right before development. So now I'm back to square one. I've tried changing cameras, lenses, film, agitation, time, and developer. I can't seem to figure it out. The testing continues.

[Jung Hyun, LEE]

Thank you. I'll develop by using your data.

Does anyone know for sure that Ilford's LC29 and HC are the same formulation (or close enough) to HC-110? They seem to be not as concentrated, but any other differences? The Ilford products seem to be a little more readily available where I am (at least the LC-29). I'd like to standardize on one of these highly concentrated syrups in lieu of mixing powders, assuming the quality is still there.

LC29 seems to be a diluted version of Ilfotec HC. The dilutions proposed for the later are common with Kodak's HC110 and development times suggested by the manufacturers are quite close, especially if you take into account that the agitation intervals aren't the same.

Ilfotec HC and HC-110 are different formulas (unlike D-76 and ID-11, which Ilford support has told me are "identical"), but standard dilutions are exactly the same, and times are within 30 seconds of each other IME. Both HC-110 and Ilfotec HC are PQ developers with high solvent action and high restraining action (meaning they are fine-grained and low-fog developers).

LC-29 is the same developer as Ilfotec HC, but concentrated differently, so must be diluted differently to arrive at the same working solution. I forgot whether LC-29 syrup is more concentrated or less concentrated than HC, but my guess would be that it is less concentrated. (HC = high concentration, and LC = low concentration?)

I developed my first roll of film at home last evening and I'll convey my experience. Previously I'd been using Arista Premium at the school but I chose HC110 for general purpose home use.

Tri-X 400 120 shot at 400 and developed for 6 minutes in dilution B at 71F. Slow continuous inversions for first 30 seconds and 10 seconds each minute thereafter. Kodak indicator stop for 1 minute with continuous agitation then Kodafix for 6 minutes with 5 second agitation each minute.

By my eye the exposure and development are spot on. I metered a prominent shadow area, placed it in Zone 3 and shot. That area has good tone and texture, so I got what I wanted.

However, I do have a darker line across the bottom of the roll. I'm assuming this was an agitation issue. Perhaps I should've given more agitation? I was using a new tank and may have pored the developer too slowly?

Overall, I'm happy with the development but think I have some procedural issues to work out.

[BetterSense]

It looks like you didn't fill your tank all the way with developer.

[SoonerBJJ]

How can you tell? I used 550ml per directions for 120.
