Arista 100 vs. Shanghai GP3 - one picture comparison

Richard Man · Feb 25, 2022

Both Arista 100 (left) and the Shanghai GP3 (right, the puppy squirmed a lot) were metered at ISO 50, taken with the same 8x10 camera, same lens, one image taken right after another. Scanned using Vuescan DNG mode and converted using Negative Lab Pro. No adjustments other than simple "auto-exposure" in Lightroom, but the un-adjusted exposures are very similar anyway.

For whatever reasons, I prefer the tonal look of the Shanghai more, but may be it's just random choice. Anyway, may be someone will find this interesting.

Thanks for the two pics. I take it that the squirming puppy caused the lady holding it to move as well and that in turn affected the edge of the basket as in the Shanghai pic the basket looks fuzzier? Overall the contrast in the Arista looks better to me and for whatever reason the picture looks sharper. If I was casually passing these two in a line my eyes would be drawn to the Arista is, I think, what I am saying

However on one example it would be unwise for me to draw any conclusions

I think you would have done better to set up a still life for this demo, motion blur negates any way of making a determination of which is better.

Richard,
I agree with what's already been said. Maybe a still life of scenic/landscape under overcast diffused light would be better. Just a thought! JohnW

Both looked overexposed by a stop to me.

Ditto. Gratuitous knee jerk automatic reducing the film speed from box speed does not help the rest of us. If one shoots box speed and always keeps the sky out of the meter field of view, the shadows will automatically appear OR shoot box speed and use a spot meter to put the shadow details in Zones 2,3 or 4 provide great negatives without all the searching for an EI.

Shots fired.

I don't think you can tell whether they are over-exposed or not - there are too many steps between the negatives and getting things visible here on Photrio to be able to exclusively blame camera over-exposure for the relatively light and washed out appearance of the results.
I do think though that we can come to a conclusion about the prudence of using an energetic dog (a Corgi?) as a test subject for film comparisons .

You're ok in my book Matty!

I'm just judging by the results posted. And they really look overexposed by one stop. How that happened is anyone's guess. But I do think that rating ISO 100 film at ISO 50 may have something to do with it.

Actually, I think the tendency to add an extra stop of exposure is often accompanied by a tendency to want to display/print things one stop lighter than average.
The "pastel" look to colour print film is a result of that apparent trend.

Thanks for all the comments. It's an unscientific "comparison", more for me just to see which brand I should sink some money onto since 8x10 are getting more and more ridiculously expensive.

Yes, the corgi pup is super energetic. For my purpose, these two pics tell me what I need. I have already shot 2 packs of the Arista (50 sheets), and I have shot a few boxes of Shanghai GP3, albeit in 4x5, so I want to see whether it behaves similarly for my purpose.

As for exposure, I'm not going into whether it off by 1 stop or perfect or whatever. It's "to taste", and it's fine by my taste. I can easily post-adjust it to anything I want, but this is a good basis for me to start. YMMV

What you guys want to pick on, is that, the light is flat, which I know. So *shrug* Here's a couple high noon picture for your enjoyment to pick on. Both taken on a Hasselblad this time
