new to HP5 in HC110

[wintoid]

HC110 w/ ilford pan F is the bomb 😀

Are those PanF or FP4?

Frank - rereading your post about the high contrast of the CV lenses and your concerns about the upswept curve of the HC110 - using a compensating semi-stand might be just the thing. Grain might be a bit more apparent, but at least HP5 has nice grain. Contrast should be well controlled using the process I described, with a nice shoulder in the highlights and shadows to hold detail.

I have not used HP5 a lot, but I have settled on Dilution H in HC110, 2x Dilution B times per Covington. All of the B&W shots in here are from my last roll with this combo.

Rover, do you scan the print with a flatbed or do you scan the negative ?

I scanned the negative. It is a flat bed scanner and I am not happy with this scan. The negative covers more area to the right, not clipping the corner of the front building but I can't get the scanner to capture that. I also cropped it poorly on the left with the street light, that was a bad day trying to present an image I actually like quite a bit.

Rover, an image doesn't need to be technically perfect to be a nice image.

I liked the tonality and also the representation and was wondering how you did it. My B&W images which I scan from negatives useually don't work out nicely, but then I've only started trying to scan B6W negs with a slide scanner.

.... I like the image !

Thank you, I identify the media as a B&W negative but scan it in color mode, then desaturate and play a little with PS. I am going to wet print this one since I can't get what I want electronicly from it.

Frank:

I just started using this combo (dil H and HP5+) rated at 400. I think my time/temp was 10min @ 20C, ~2 inversions every 2nd minute. I was trying a "semi-stand" approach, but I'm not sure I nailed it. The negs looked kinda flat to me; sorry I don't have the scans to show at the moment. I'm going to try it again, however, possibly moving up to the 1:100 dilution as rogue mentioned.

FYI, I also recently used dil H (1+63) for pushing a roll of Tri-X (400TX) rated at 1600; these negs seemed to work out a bit better (I was shooting for contrast). No scans yet. Here I used what some folks have called the "Merciful Semi-stand" approach, which I realize he developed for Rodinal...21min @ 21C, 1 inversion every five minutes.

Enjoy.


Cheers,

Just to make sure I understand 1:49 means 1 part HC110 and 49 parts water?

Thanks.

Hi Frank,

I have finally settled upon 1:49 (from concentrate) for 8 minutes at 20C, EI 320 for this combo. Agitation is constant for the first 30 seconds then two gentle inversions every minute thereafter. If the light is very flat, as it frequently is in my part of the world, an extra minute or two keeps things from looking murky. These times are for wet printing, if you're planning to scan your negatives a slight reduction may be called for.

Hope this helps,

Jim.

dilutions: guess I gotta try them all 🙂
Thanks for everyone's help!

 

[planetjoe]

Yep.

Well, that's what "1:49" usually means as written, but sometimes I've heard it misinterpreted as "1 part out of 49 parts total solution", which would be incorrect. Not often, but still.

Occasionally (especially for HC110, IMO), dilutions are written like "1+49", which I personally find to be a bit clearer. 1 part solute plus 49 parts solvent. In this way, you can see that there will be 50 parts total, of which 1/50 of the final solution will be the solute (i.e., the developer).

The only problem with this method is the math behind the mixing...for example, i you want to mix 500 mL total with a 1+49 dilution, how much solute stock will you need? Well, in this case it's (500 mL / 50 parts = 10 mL solute), not (500 mL / 49 parts = 10.2 mL solute), which some might think would be the case from the "1:49" notation. Of course, at these dilutions the difference isn't all the great. That's actually one of the things I like about high dilutions.

Boy, now I'm rambling. Forget it, it's been a long math day. Forgive my mistakes, if any.

Hi Bad Monkey,

You are absolutely correct, I dilute 1 part HC-110 concentrate diluted with 49 parts water. I could have made that clearer. Apologies for any mental anguish I have inadvertently caused!

Cheers,

Jim.

I use dil B for 6 min at 20 C. The water is important factor. I use filtered water for development and fixing. Amazing developer. I am sorry I can't get the concentrate in my country
