The Imagon is a simple construction, but in it's simplicity it is also beautifully designed. It is an old type of achromatic lens - two elements in one group. Am I correct that the rear element of a Tessar lens is, like the Imagon, also an achromat? Could I use this rear element alone as a soft...

Thank you mollyc, that is a good example. Good information about the Portrayer filters, thank you xkaes. Also thank you for mentioning the Seagull, I will look into it.

That idea is very interesting.

None of my browsers open the website unfortunately...

I don' know yet if I am going to buy a Helios and perform surgery on it, but I sure would like to know more about that.

Good day all, thank you for your replies. I experimented with lots of soft, haze, mist and diffusion filters, including Zeiss Softars. But I haven't tried them all yet, maybe the Minolta Portrayer is nice. However, to my opinion nothing beats a proper soft focus lens. The Lensbaby might be...

Dear Apug / Photrio community, For years I have been working with a Rodenstock Imagon lens. I have the 120, 150, 200 and 300mm. I mainly do landscapes on 120 or 4x5. Lately I started to photograph some architecture with it. The Imagon is an achromatic lens equipped with diffusion or sieve...

Hello DAP, Is the soft focus lens still available? Please let know.

I liked to have one more stop for shorter exposure times. Also, it gave me the possibility to develop TMX and TMY together in one tank, because TMX @100 TMY @800 have about the same development times - in my experience.

I always shot 35mm and 120 TMY at 800 ISO. Developed in Tmax developer 1+4 it gave excellent results.

Years ago I did use R3 35mm at 1600-3200 iso in low light situations and back then I was happy with the results. But my vision on grain and contrast has changed over the years so I guess I should have look at those negatives and think again.

Well, it seems that the R3 needs a dedicated developer for the best results. A pre-rinse of about two minutes is also strongly advised. I have also tried Rodinal and D-76 in the past, but it was not really nice. The dedicated RLS (low speed) developer was good for exposing at lower iso. I am...

Thanks for your advice. Actually I am suspicious too and I don't think it will give consistent results, so I will forget about the old RHS developer. But, now I need an alternative. In my darkroom I still have Tetenal Ultrafin T+ (sort of a Tmax developer). Does anybody know if this is a good...

I have several small bottles of Rollei RHS developer which I planned to use with some R3 sheet film that is still in my freezer. Unfortunately, I found out that all the RHS developer turned really brown. It was stored in a cool and dark place, but now it has about the same colour as stock...

HDPE: almost all the bottles that cantain chemicals in my darkroom are made of this stuff FEP: for really nasty stuff Glass
