Need help to improve this photo + zone system qnses
Hi ppl,
First of all, I've been taking this scene on and off for the past 6 months, with different kind cameras. Finally I had the chance to try it with a 4X5.
Polaroid 110B, f32/15mins
Shanghai 100
Rodinal 1:50, 13.5mins, constant agitation

regrettably, the polaroid have no movements, a view camera will be better suit due to the perspective of the buildings, i believe?
However to make do with what i have now, how can i improve the picture?
On a side note, I want to try the zone system,but how did you find your N+- timings?
I presume there's no easier way then to trial and error?
Any help is appreciated! :)

That picture looks fine. You can level the camera L-R, which will minimize perspective distortion.
There are numerous texts to learn Zone System technique from. They all work; try one and follow it. Many people will have opinions about which to choose; I'll just suggest that you avoid the original Minor White 'Zone System Manual', however, as it's the most difficult to understand. Have fun!

Expose more, and develop less: boost the low values, and subdue the high values.
You might want to explore the forms of long development, called "Stand Development" and "Semi-Stand Development" - where we allow the film "stand" in the developer for a long time with minimal agitation. You can Google the term and learn a lot about it.

Improvement depends wholly on what you are looking for - and that I don't know. But for me I'd do a couple of things to avoid the high contrast shown here. First I'd divide the exposure: for the shadow area I'd make an exposure at dusk or so in order to capture detail in the shadow areas (shove it around zone two or three). Now leave the camera absolutely fixed in place until dark and do a second exposure (double expose) at a small aperture for the lights. The second exposure should yield good definition of the headlight trails and add some brightness to the higher shadow areas. All this being quite tricky to accomplish. If you then come up with some reasonable estimate of the equivalent brightness range and you can employ some version of variable development as mentioned above then you have a chance of obtaining a full tonal range negative - if that is your intent. But I also do like your version of the scene above. :)

I like your image the way it is, very nice

If it's not too extreme, a fair amount of "perspective distortion" can be corrected by tilting your enlarger easel, or easily done in PhotoShop if you're printing digitally.
Continuous agitation will INCREASE contrast.

Zone system is a tool to estimate exposure and predict tonal values in the print. Since you have already exposed the negative and made a print, you are way ahead of the approximations the zone system can give you. Now if you want to work backward from your good print and negative to make more pictures of similar subjects zone system could help.

I'm with Ken on this one. Try more exposure to bring out detail in the shadows and raise your mid tones. Compensate for the additional exposure by holding back development to control your highlights. Take several shots and experiment with development times.
Re: Need help to improve this photo + zone system qnses
Firstly, tks guys for taking your time to help!
For me, my ideal final image is to have lots of details in the shadow areas (main building, trees), yet not blowing the exposure for the bridge. For this shot, I could not pull out any more shadow details, I presume I must go earlier the next time, to have the tree's details.
I will try what ken and robert's suggestion and expose for the trees, and dev for the highlights. Been reading a steve mulligan book about this. Just find it a hassle to find my dev times. haha. guess i can't escape it.
I'll try nathan's double exposure too, that seems workable provided I nail my tripod down. haha. Is there a name for this method? Maybe i can find out more about it.
I'm printing digitally and will prolly correct the perspective using photoshop, till i get a graphic view at least. :(
Thanks for all the help again!
Re: Need help to improve this photo + zone system qnses
One other trick that might help put a little density in those shadows is flashing the negative. With this method, you expose the negative to an out-of-focus gray card to about Zone 1 (four stops down from your meter reading of that card). That isn't enough to wash out the shadows, but it will move the additional exposure further up the film's response curve, hopefully beyond the toe where you can get some tonal separation.
Also, a big flash might actually be able to expose the closer bank of trees that are in silhouette to Zone 2 or so. It make take a few firings, but with a 15-minute exposure you have time. Just don't do it enough to make it add more than a bit of density to the dark parts.
But I think the best solution is to wait for a more humid evening, and let the humidity spread the light around a bit. That will also add a bit of density to the sky in background as the humidity is illuminated by city lights.
