I have what I believe are my perceived differences between these two, but the only differences that seem to be apparent based on the Ilford. ILFORD PQ UNIVERSAL is a liquid concentrate dimezones/hydroquinone developer suitable for the dish/tray developing of all RC and FB black and white. Hi, I’m a bit confused. I bought a new bottle of developer a couple of days ago because it is listed as ‘universal’ for both paper and film, There is.

Jun 5, 1. I have what I believe are my perceived differences between these two, but the only differences that seem to be apparent based on the Ilford literature are: PQ is not called “rapid,” while MG is though the development times are the same for both developers 2. MG gives a “neutral image tone with most papers,” while PQ gives a “slightly warm of neutral” tone.
MG is not recommended for film processing, while PQ is called usable for big film but not for 35mm. MG can be used at 1: Is the only big difference that MG more potent?
It would be interesting to hear what you all have to say about these two developers when compared to each other, and even more interesting to hear what Simon from Ilford has to say about it. What are the actual differences in the images? I have to special order PQ from Freestyle, and most people I talk to have never even heard of it. I am very interested to hear why there are both varieties.
Who uses which one, and why is PQ harder to find, while MG is everywhere? I find that when comparing two Ilford products on paper, it can be difficult to figure out exactly what the differences are enough to univrrsal a choice.
A comparison chart of some sort, and detailed technical publicationswould be a real help. It seemed to be much more easy with Kodak chems, but maybe it is just me!

Why does Ilford hold out on so much published technical information compared to Kodak? Last edited by a moderator: Jun 5, 2. From what I could gather it gave him a better print and one which was considerably warmer than MG in FB paper. I haven’t used PQ but thrown this in because it is clear that in his case PQ gave him a “look” which MG couldn’t match.
Jun 5, 3. It’s easier to start at the beginning. Ilford sold a developer called ID a Universal MQ dev mainly used for prints, when they began commercial production of Phenidone they reformulated ID with it instead of Metol early ‘sthere were complaints about shifts in image colour abnd variations in warmth, so they added Benzotriazole to control this the new formula was ID These where powder developers.
PQ Universal is great for film processing, especially when highly dilute, Ilford no longer give all the data that was once available in the past. The Multigrade dev is specifically marketed for papers but it’ll most likely work for films as well, concentrations differ.
Jun 5, 4. Eliminates toning introduced by the developer? To me, I find the largest difference to be in the whites. I find PQ a bit punchier there, while MG is better for taming contrast and getting a slightly softer look in the whites.

Perhaps what I am seeing is not a difference in curve shape at all, but just a slight difference in tone? If this was the case, I’d think I would see the opposite, however, with the slightly warmer developer making the highlights look a bit more soft. Where does Bromophen fit into uiversal picture? Jun 6, 5. Ilford now use Dimezone instead of Phenidone in some liquid developers.
PQ Universal unviersal very clean working as a negative developer and this carries through when used for prints as well, giving the punchier highlights.
Two other factors can affect image colour, liquid developers use Potassium salts instead of Sodium because of the greater solubility and this also increase the warmth, and this was particularly noticeable with Agfa WA where the powder version an MQ developer was significantly less warm than the liquid PQ version.
MQ developers are colder toned than the equivalent PQ version. Apr 27, 6. Bumping this as I have a related question. Unfortunately, I ;q the packaging after I decanted the remaining stock solution into smaller full bottles. I made note of the lot number and nothing else. The lot number is: I need to reorder, and I want to make sure I get what I’ve had all along. Apr 28, 7.
I have used both, but much prefer the MG developer as I like a yniversal cool, “neutral” color to my ilfrd. This was not subtle, there was a marked difference between the prints, klford much so that I only used the PQ once before going back to the MG. You must log in or sign up to reply here.
