My session timed out and I lost my post; so here is the short version:

I learned on digital, and now I have a Leica M3 and some film & slides. My brain did some backflips along the way. There are many things I'd like to share, but this is just one post and I don't want to bore everyone with novelties that have probably been discussed already.

So here is what this post will be about:
First, I'm pushing Tmax 400 to 1600 in Xtol and I think it's great. The challenge was I only found a couple recommendations to push Tmax and even less examples of photos. Whereas the standard recommendation seems to be Tri-x & I think Diafine or similar.

Second, I am using my dslr to "scan" my negatives and again, the results seem fantastic. I've read some heated debates about scanning film with dslrs and I have to say it's a viable option with B&W film at least. I'm interested in seeing the results after I try a roll of slide film.

Anyways, here are some sample photos of TMY400 @ 1600. I'll give details after if you want to keep reading.

This one was shot at f8 and seemed to be the sharpest on my roll:

So that's it. I think I am most excited about (ironically) digitizing my 35mm negatives in so much detail. Perhaps my expectations were too low, but I've been hearing of so many problems being able to make large prints from 35mm scans. So far I hardly see that being a problem for me.

And now for some detailed info:
These shots were taken with a leica M3, Tmax 400 pushed to 1600 (because hey why not), and a 50mm collapsible Summitar lens @ 5.6 and 8 apertures.

I shot two rolls this way and developed in Xtol @ 78 degrees F, because I live in a NYC apartment and have nowhere better to do this. The 1st time around I developed for 6 minutes in stock solution (hoping the shorter time would make up for the heat) and found my negatives were not dense enough. The 2nd time, I upped to 10 minutes in Xtol stock and seemed to hit the nail on the head. Both times I washed with water only, fixed for 10 minutes with the cheap-o kodak powder fixer, and again washed with water... this is a bare-bones setup.

The "scans" were taken with a Canon 1DS mark ii, Canon FL extension tubes (yes, FL; they came with a FL macro bellows which I ended up not using here) and a Canon FD 50mm f3.5 macro lens. The significant takeaways here were that f3.5 give acceptable detail (the 1st 3 images above were scanned @ f3.5), however f5.6 is much sharper in the center & corners with better contrast, and f8 the same in the center but even better in the corners. The last image was "scanned" at f8.

Oh and one last thing - I found backlighting my negatives with natural light was far superior to using artificial light because artificial light's color balance is so warm I get artifacts if I get aggressive with curves in the shadows.

Thanks for reading.
 
Nice results. I haven't pushed 35mm yet, but I will when I get a lens for my M4. Have had very good results pushing Tri-X in 120 format to 1600 in D-76 1+1. I live in a tiny apartment in SF but developing in my kitchen and scanning on a V700 is super easy. Post more please!
 
For more information, check massive development (?) chart for times and temperatures. The Anchell and Troop Film Development Cookbook also has a time and temperature chart for Xtol diluted for one-shot use. The developer can also be replenished, using itself as a replenisher - check the Kodak website.
 
Pushing = underexposure + overdevelopment = increased contrast.

I was in love with it when I was younger.

Now I realize how little shadow detail my old negatives have, and how contrasty they are.

There is a reason for ISO speeds.

Cheers,

Those photos do not seem overly contrasty to me. I have not tried to push TMax 400, so your results look very interesting. I often shoot Tri-X @ iso 800 and develop in Diafine, and generally get very nice tones.
 
I think you owe it to yourself to get a few comparison scans done by more conventional means. If you're going to accept the costs of shooting film — time and money — you ought to be sure your dSLR 'scanning' technique is giving you (relatively) good results. It's difficult to tell, here, if it's the developing or the scanning that's letting you down. The last image looks nice tonally, but all are on the 'soft' side. Are you sure that's what's on your negs?

What are you using for a light source, and what holds the negs flat?

Thanks I actually started there. Most of the dev times are around 20C so I had to guess a little. Still, I think if my apartment were 20C and I used the recommended time for Tri-x @ 1600 in Xtol my negs would have been very under developed.

Although I sort of broke every rule in the book right off the bat (e.g I'm storing my Xtol as a 2l concentrate) so don't everyone take my word too seriously! 🙂

I think there are a few things at play. The 1st 3 are admittedly soft 'cause I "scanned" the negatives wide open because I hadn't rigged my lens to stop the aperture down yet.It also likely happened in camera because I am still learning to focus a RF. The 1st, I missed focus on my kid's face but @ 100% you can see the weave pattern of his jeans. The 2nd I hit the stroller alright but... you get the idea. #3 - sh*t was just moving too fast for me; I think that was 1/30th second or less. The last one.... I was pretty proud of the sharpness and even "scanned" at f8. Did you look at the the full sized image? photobucket is preventing direct links to the full image so you have to keep clicking the magnifying glasses to see it.

Anyways, I'm using the slide duplicator attachment from my FL bellows & window light.

edit: oh right, plus the summitar (maybe even the macro lens, dammit) I am shooting with might explain some of the corner softness. Honestly I have no concrete idea yet since I'm new to virtually every detail of shooting with leicas, developing film, and duplicating negatives (which is why it's all fun to me).

Edit 2: and yeah I can't argue about trying a scan with some more conventional means. However, that will have to wait (for my $$ to rally)... my film isn't going anywhere. My philosophy with the leica is this is the camera I can take whenever I don't want to lug my dslr beast around. It's exceedingly annoying after an entire day carrying even in "street" mode with no extra gear and a 50 prime. Somehow this makes the leica seem more fun to me - I'm going to enjoy the quirks of film and embrace the flaws. Something I can't seem to do with digital.
 
I like your pictures very much, but I'm curious as to why you use a polarizer, given its many limitations, rather than say an orange or dark yellow one.

Thanks! Well I would definitely rather use a color, it is just what I have available to use. I only have a dark polarizer in that diameter filter.

I only like to use B+W filters, and after slowly accumulating Leica size ones, I then had to get some for the Xpro1, and now Mamiya size will take a while but I will get the basics. I wish I started the other way around and then just got a few step down rings. 🙄
 
Anyone want to loan me a scanner? 🙂
So who else has some full res scans, or ~16mp dslr scans? Is the curve and/or resolution of the last photo in my post really so bad?
 
Am I wrong in thinking that hi-res scans are wasted on the web? I'm just learning with my new V500, and I read that everything over 72 ppi just slows down the loading of the image, as the monitors can only deliver 72 dpi. I've been scanning everything that way and about 10 inches wide, and it seems to look fine on the computer screen. I only print silver-gelatin wet darkroom style.
 
I think the shadow detail is fairly good for tri-X at 1600. I shot a show and pushed to 3200 and shadow detail was basically zero. Hard lighting has something to do with that also.

Yeah I think it's definitely a waste on the web unless there's some reason you need an image much larger than most monitors. However it's just nice to know one has the ability to pull out every last bit of goodness from a (35mm especially) negative for a large print.

What is the use of a 72dpi scan file of 35mm format? That's hardly a thumbnail. An image with 0.5cm in width on a retina display.
