Anyone know how well Kodak 50D does when pushed?

Disconnekt · Oct 2, 2021

Like the title says, anyone know how well Kodak 50D* does when pushed to 100 & 200 ISO? Has anybody shot it at 100 & 200 ISO before? Does it look good/bad/meh when pushed? I have a stash of Kodak 50D in bulkloaded 35mm rolls (I bulkloaded from a 400' roll a friend gave me), and was thinking of shooting a couple rolls pushed to 100 & 200 iso, but wanted to see if their was any examples** of it being pushed out there.

I do plan to send them out to a lab to be developed in ECN-II chems, so getting them deved in the proper chems isnt that much of a issue.

*Talking about the OG Kodak film that still has the remjet on it, *NOT* talking about the Cinestill version.
**The "examples" of the film being pushed is of the Cinestill version (which has the remjet already removed & cross processed, which gives it a completely different look), which isnt what Im looking for.

Sorry, I'm only a beginner with the film and can't help you with the push question, having only shot at box speed and processed at home. But I am wondering where you found a lab that will develop it and what they charge. Will they do push processing?

The lab is called Need Film Developed (theyre in Pennsylvania), and only charge $10 for ecn-II developing, and he does do push processing (up to 3 stops, doesnt charge). Here is his site with more info in it: https://www.needfilmdeveloped.com/the-lab/p/ecn-ii

The only other lab I know of that does ECN-II processing in ECN-II Chemicals are Bellows Lab (down in Florida,), and they charge $9 bucks a roll, and they charge for $2 bucks for each push

These labs do process ECN-II films, but they all cross process them in C-41 chemicals:
Blue Moon Camera ($20), Old School Film Lab ($18.75), Boutique Film Lab ($10), and The Camera Shop ($12)

When I was evaluating this film for possible use I found it needed to be exposed at about 25-32 for decent results when printing onto RA4. 100 or 200 may be fine for scanning.

Why not look at 250D instead if you need more speed? Makes much more sense IMO.

I do plan to digitize it with a dslr down the road.

Because like I said in my original post, I already have stash of 50D that I bulkloaded from a larger roll (currently have 52 36exp rolls), so Id rather use what I have & know that I can push it in a pinch, instead of spending money on just buying a couple rolls of 250D to shoot

100 may be ok, I don't think 200 is going to be a winner.

Here's some 16mm 50D (7203) strobe exposed at 0, -1, -2, and -3 (effective ISOs 50, 100, 200, 400) @ 1/125s f16 and developed in ECN-2 N+2 (4m 40s development time). Temps may have been a bit low but 200 w/ N+2 (more like N+1.3) is usable.

The scan correction is the same applied across all frames, so there's probably more detail in the higher ISOs if you're willing to tweak your scanning process.

100% crop from ISO 200 (3rd from the left) and after setting the white point and reducing contrast.

Rating at 400 with in-spec N+3 development is probably a good practical limit, taking caution to avoid high contrast lighting unless you want blobs of inky shadows.

That looks amazing!

I've shot 50D 16mm at 100 no issue. I gave it a slight push in C-41.

Modern ECN-2 stocks are pretty incredible, particularly suited to 16mm stills shooters (and cine uses obviously). The ECN-2 developer is oh so slightly easier to mix from scratch than C-41 (e.g. there's no futzing with iodide or hydroxlyamine sulfate), the ECN-2 color agent is shared with the E-6 process, and since 16mm takes a dedicated tank I'm not tempted to cross-contaminate my 35mm tanks/reels with the scourge remjet.

Inversion/color corrections at scan time due to out-of-spec chemistry or processing are typically easily correctable by scanning software or simple level adjustment. C-41 is a bit more complicated in that regard, particularly if you aren't a person running a commercial lab.

I've stuck with Ektachrome in 35mm for the time being owing to its lack of remjet but my experiences with the 16mm stocks will probably have me shooting short loads of 12-18 yankee-clipperable frames of 35mm Vision3 before long.

Edit: Here are 400, 800, 1600, and 3200 ratings under strobe, ECN-2 N+3 (5m 40s, bleach bypass), default scanner correction for each frame. 6400 was unusable.

And alternately from a positive scan inverted and black point set:

I'm still developing mine in C-41. I have a dedicated toothbrush and some dawn for the Jet

Echoing other people's suggestions, 250D is a nice and clean film so it will always do better than 50D at ISO 100 and above. The only reasons to push 50D would be if that's all you have on hand or are severely budget-constrained.

For me thats all I have on hand right (52 bulked rolls left from a ~400 foot roll a friend gave me), so for me I'd rather shoot what I have & know that I can push it in a pinch to a certain ISO and get decent results.

200 ISO was pretty much the highest I was willing to push it, and by looking at the examples from Bronson it looks like when pushed to 200 it will still give good results, and ok results when pushed to 400.

Anyone know how well Kodak 50D does when pushed?
