Arista EDU Ultra 400 push/pull ability?

I get pretty much the same results whether I use my Pentax spotmeter (vintage), my Sekonic Studio Master (vintage), my Mk. 1 eyeball with Sunny 16 (vintage), or my smart phone with a light meter app (averaging or spot). With the smart phone in averaging mode, I do take care not to include too much bright sky etc.

That's interesting! I find that the matrix meterings I take with my Nikon film cameras, while agreeing amongst themselves, often substantially disagree with the incident meterings I take with my Sekonic L-398 III, the latter giving me results I prefer and trust more. I haven't had much lack with phone metering apps, which I've now stopped using altogether, but the culprit here is probably my Android phone. I would imagine that any variability in phone sensors and cameras might result in metering inaccuracies if that particular model/brand of phone wasn't tested by the app developer. Different story if one owns an Iphone, I'd imagine.

With 4x5, I've preferred the results at box speed.

I used two different cameras trying Fomapan 400 at 320.....Nikon F601M and Praktica BX20S....the former in centre-weighted mode and the latter only offers centre-weighted. I found everything I shot outside had blown out highlights when I don't get that at box speed with any other film. so I started shooting Fomapan at box speed and it works better for me. I've since used it in medium format with vintage cameras and "sunny 16" or phone apps. I tend to find that a phone app is mostly just useful to confirm my "guestimates".

I am experimenting with HP5+ 120 film at ASA 800, developing in D-23 1+3 for 20 minutes 68 degrees. First try at printing: found a time to get a very nice clean white and long midtone scale. However, at this printing time I do not get a good black even at B+F. Any helpful suggestions on what to do next?

Not sure about D-23 because I've never used it, but HP5+ shot at EI800 develops nicely in D-76, prints and scans nicely too. I would recommend opening a separate thread dedicated to this matter - more people are likely to look into a thread called "HP5", rather than "Arista something something".

Thanks for your help. Posted this to thread D-23.
