HP5 in DD-X or HC-110? A [non-scientific] Comparison

So after seeing a certain forum member's experience with DD-X I bit the bullet and ordered a bottle. Working on the basis that my HC-110 will last forever, I figured I could just use up the DD-X whilst I was shooting through my bulk roll of HP5.

I spent the latter part of 2018 and all of 2019 with Rodinal, and I made the descision to spend 2020 with HC-110, but to be honest, after my first few rolls, I found it delivered far superior results to Rodinal for the films I shot and the look I liked. HP5 in Rodinal looks terrible to my eye so it's not included here.

Pricewise DD-X is expensive. I'm going to quote price per film rather than price per bottle because dilutions etc will make a difference. Rodinal at 1+50 weighs in at 35p per 35mm film. HC-110 at 33p (1+31) and DD-X at a whopping £1.08 (1+4). That's triple the price of the cheap stuff and obviously would require more orders for the same volume of film, so you've got mopre postage to add onto that. Obviously it's still cheaper than B&W lab development, but it's the second most expensive liquid developer on the market. (Kodak TMAX wins).

This isn't a scientific experiment because I was dumb. I put rolls of HP5 into my Olympus 35RCs and set the ISO to 800. I have 2 of these, so figured that would be a good idea. Stupidly though, I didn't think that the meters would be slightly diffferent, and the RF patch is harder to spot on one. So both focussing and metering weren't exact.

Yeah. It doesn't say hello (badly) it says hc110... So my initial thought was that there really wasn't a lot in it. The HC-110 camera was probably exposing 1-2 stops under, whilst the DD-X camera was about half a stop under. I don't think this has helped the situation, but there were a couple of photos on the contact sheet where the HC-110 camera had obviously metered a bit brighter.

To start with, IMO, the DD-X isn't 3x better. It's not noticeably sharper (take my word for it because forum compression will kill these screenies) and whilst the grain is lessened, it's really only visible at 100% which as any pixel peeper will know isn't that useful.

However where the difference is clear is in what I'd call zone II to zone III shadows.

Above you can see the man in the moon thing that my wife loves is quite clear in the DD-X dev, whilst it's lost in the HC-110. Now this could be down to the fact that one camera is under-esposing, but the sofa and carpets (whilst less in the HC110 image) aren't that far out. Looking at the rest of the contact sheet, that gives me confidence to say that DD-X is likely to be able to pull more detail from the shadows. I also like the way it renders the texture too.

So will I continue to use it? The jury is still out. The shelf-life is (apparently) 3-6 months once opened which isn't great compared to the Kodak developer and Rodinal. A 1l bottle will also only develop 16 rolls of 35mm or 10 rolls of 120 which means lots of reordering (1l of HC-110 will do 106/64). I'm going to use the remainder on some more HP5 at 400 and 1600, as well as some P3200 which I roll out at this time of year. Lots of high speed stuff which Rodinal really hated, but HC-110 seems to deal with quite nicely.

Certainly, the developer is not hampering my capability as a photographer as I perhaps suspected. It must be something else :)

Do any of you have any thoughts on this?

I was using DDx then Robinal now on DDx again. It is expensive like you say. I should try The Kodak stuff, the shelf life is very appealing.

When you use HC110 what dilution do you use?
 
Dilution B, 1+31, or the imprecise "10ml in about 300 and 15ml in 500".
 
I guess I might be the unnamed forum member you mention? :)

I really like DD-X and plan on continuing to use it, but I can't offer much in the way of reasoning as to why it's better than anything else given that it's all I've ever used since I began home-developing in the spring. I have used Rodinal (in the form of Adox Adonal) on one roll of Fomapan 100, and I wasn't unhappy with the results, but I still prefer the way DD-X works on the same film. For everything else DD-X has produced results I'm very happy with - just as nice as the lab results I've had in XTol - and it's handled everything I've thrown at it with aplomb, including pushing HP5+ on and two stops (I also plan on shooting a roll at 3200asa at some point to see how that fares).

It is more expensive on a roll-for-roll costing, but I've also found that it's cheaper to buy a bottle than the more economical developers. It's a false economy, but sometimes it works for the wallet that way.

If you have any Shanghai GP3 then MDC only gives times for that with the more economical 1+9 dilution, so a minor cost saving there. :)
 
Many thanks for this thread. It's interesting to read of others experiences, and I'm impressed by anyone who takes the trouble to test things like this.

To all intents and purposes, I've only used two developers (apart from a few one bottle only tests), Unitol (for no better reason than AP used it to develop their ship picture lens tests in the 1960s) and Rodinal after Unitol was discontinued. Rodinal does give more grain, which I don't like, but my switch was after I moved up from 35mm, so it doesn't matter. On my prints, I can't say I've ever seen any difference when I tried something else, except for one film where I used the then new Acutol.

Oddly enough, I do have a couple of other developers in hand now to use, so it will be interesting to see if I spot any differences. Not that I'm doing any controlled tests like you.

So interestingly, whilst I was developing the 2 test rolls I also had a roll of HP5 shot at 1600 to do. I decided to dev it in DD-X.

1600 is a "normal" ISO range for me at this time of year. It's often gloomy, and I walk in the woodland with "lighter" camera combos which usually means no more than f/2.8 to rely on.

I don't have a direct comparison to HC-110, but the grain on this was amazing (for 35mm)

Canon EOS-1v, 40mm f/2.8 pancake, HP5 Plus @ 1600 in DD-X (1+4) for 13min.

This is a [post-processed] shot in gloom at 1600 ISO. It looks fab. One of the things about high ISO film is that it can be very difficult to pick out the image from the grain, which makes sharpening difficult (because you're often sharpening the grain even with masking) and noise reduction also difficult (because there's so much noise, the software drastically softens the image part). In my opinion, DD-X provides a clearer image through the grain which makes subsequent NR and sharpening much easier. Also, the additional contrast of the longer developing time has been mitigated by the characteristic of the developer to better control the tones.

My 1600 ISO options are realistically, HP5 Pushed 2 stops, or P3200 shot at 1600. I have a lot of P3200 in the fridge because of everyone selling off their expiring stock. It wil be interesting to see what it does with TMAX. But this is a similar [also post-processed to try and control the grain as best I can] gloom shot at 1600 developed in HC-110

Grain is much more pronounced, esp in the zone II & III shadows and there's a "kludgy", muddy look to the image - which suits the subject in this case. This grain is less pronounced through the tonal range, but it's visible, and nowhere near as clean as the DD-X shot. I may well sacrifice a couple of rolls of P3200 to compare.

If this lasted longer I would definitely keep a bottle for high speed film because my initial tests show that it can deliver pretty nice images.

Really interesting to see these results, my go to is HC110 just because of its shelf life but may be its time to try DD-X

However where the difference is clear is in what I'd call zone II to zone III shadows.
I wonder how much of that difference is due to shooting a stop or two under rather than the developer, time for another experiment?
This guy tests a variety of films and here is his HP5 test -

Thanks for that Chris. I do watch his videos (he's gone a bit quiet since moving over here) and didn't realise he'd done one on HP5

Having thought more about this, the cheapest I can see for DD-X is about £21, so that would make it £2 per film for 120. On the other hand, @Asha has beeen experimenting with small quantities of developer in his Paterson Orbital and a realistic amount might be 100ml. At 1:4 that would only be 20ml of developer, so a whopping 50 quantities for 1 or more sheets @ 40p a go. (y):)

£18.98 (inc. shipping) at Wex. :)

Potentially 22p a go based on the last experiment using 55ml solution of hc-110 to soup a full tank containing four 5x4 sheets ;)

So possibly as little as 5.5p a sheet....how cheap can it get lol
