So I shot a test roll doing exactly this out on a trip last weekend, wasn't actually that bad to get used to (turns out I can meter while the film isn't advanced too). I would extend the bellows, then meter, then advance the film, and then take the shot before closing the camera. I do see an improvement but strangely enough there's a few shots on the roll still that definitely have some center sharpness loss still. The affected area does seem to be smaller at least.

At this point I'm still confused why I still have film flatness issues from the center point. I do have a few pictures on the roll that are perfectly sharp corner to corner so I know there's a "right" way of doing it. I'm not sure what made those pictures any different though, but the next thing I'm thinking of trying is to open/close the bellows slower and more gently than before. And to immediately take the picture after winding the film, rather than just a few seconds after I decide I'm going to take it with the bellows extended.

I was curious about when I bought my GW670 iii, in 2015 from KEH as a BGN condition, but it was honestly pristine except for a slightly bent strap eyelet.

It hasn’t needed any CLA at all and it’s been my main MF cam since then.
Can’t recommend it enough.

[Agitation Speeds]

The CR1 is programmed to spin asymmetrically, 4 seconds one way, and 3 seconds the other. This timing offset allows for more even development.

The RPM of your film tank varies based on its circumference. The smaller the tank, the faster it will spin. Correspondingly, the larger it is, the slower it will spin.

With the speed control dial at 6, the CR1 will rotate film tanks at a speed similar to that of a traditional rotary processor.

At this speed setting of 6, a 15XX style tank will rotate at approximately 75 RPM. This is a good starting point for C41 film and most black and white film stocks.

A speed setting of 7 can be used for more contrast, and this is recommended for flatter film stocks, or when you are pulling film.

A speed setting of 5 can be used for less contrast, and is a recommended for more contrasty film stocks, or when you are pushing film.

With a 15xx style tank, the CR1 maxes out at around 100RPM with the speed control dial turned the way up to 8.6. Strange, I know. Hopefully one day we’ll be able to get custom knobs made..

The maximum speed setting is especially useful during the pre-rinse rem-jet removal phase of ECN-2 processing, as this super fast agitation mimics the water jets used in this process, and helps to remove rem-jet.

For film tanks with over 2L of chemistry, it is not recommended to go above a speed setting of 8 for prolonged periods of time (longer than 30 minutes).

Baby bought its first 4x5 camera and it came with a heavily used Bogen 3047 tripod head. One of the axes requires a lot of force to properly lock, and in the process I always end up moving the camera, so it requires lots of locking/unlocking until I get it right. Is this something that can be easily fixed? Would a new Manfrotto 229 resolve this issue?

Glass on the scanner at school is rough and I haven't gotten to mowing the grass with the heal brush yet but you get the idea.
I've done 8 frames so far with the Cambo 4x5. These are four of them. Scanning takes forever at 32000ppi 👀

My scanner is ??? weeks away (untracked international surface mail, womp womp), I just chucked a big sheet of translucent white acrylic in with my ruby acrylic order to see if I can get some DSLR scans in the meantime.

1200dpi is probably overkill, just saying.

Is anybody else wasting Instax film on a 4x5 camera?
I've always wanted to mess with large format and I'm finding that combo to be a good starting point.
Curious about other people's experiences.

When I got my Instax back, I was still learning how to actually shoot large format and the instant feedback was really helpful. Just a little added benefit, aside from a pretty cool little picture. Also a nice thing you can gift someone if you're using a model for portraits.

I managed to fix my ancient preproduction Phaseone P45+ digiback for V-mount which broke about a decade ago and I never got it repaired until now. It was just a smoked DC/DC converter which I could bypass with an auxiliary battery pack with its own converter, injecting power through the firewire port.

I went for a photo walk in the city and I liked. the results. I had almost forgotten how much I loved the Planar T* 80mm f/2.8. I also am glad I held onto my old Hasselblad 501cm. But I am getting old, and in the decade since I last used this camera, my vision has decayed a bit and I now think I need to find a pentaprism viewfinder for it with a diopter.
