Wondering if they are all 4x5?

They are not as regards the DIYs. But, for lenses, I have different DIY sets that can cope with 6x6, 6x9, 6x12 and 4x5.

The DIYs are made to take advantage of the large image circle of the medium and large format lenses. They are capable of shifting both vertically and horizontally. This mobility allows for a better savage of the scene covered by the image circle, so I can subsequently do PhotoShop stitching to create, for example, panoramic shots.

In the absence of a decent life-view function, focusing is a nightmare for DIY perspective-control cameras. Digital backs with life-view functions are of a price that soars, too extravagant for amateurs. An easy way out is to make use of the life view function in mirrorless full-frame digital cameras. All of my DIYs depend on the mirrorless camera to thrive.

4X5 ... very interesting; I would love to try if I know how to develop negative films and print black and white shots.

You know how to play around with negative films. I am sure you must have great fun when you work on dry plates. Looking forward to your shots.

The following is a shot I took using a DIY camera in which the central axis can be misaligned. In my DIY, there are a front standard and a rear standard and in between is a opaque black bag to allow for tilting. I have coupled a Sony A7 and a Schneider-Kreuznach Xenar to the front standard. In the shot, I tilted the front standard upward and twist it a bit sideway too to make the out-focused parts of the shots buttery in ensemble.

very interesting.  It takes a long long time for one shot, and try and error.

I see from your photos an obsession with perspective...  or to accept only the right perspective without distortion, and wide angle is not your friend.  ANd that's what attract me.

Perspective control appeals to me because it helps to reproduce a scene in an image form that resembles the original. Images reproduced are more lifelike and natural in ensemble.

Distortion control is a formalist or structuralist approach towards photography. It takes time to take a shot, so lacking a timely response to things happening around us. Appreciate your effort to capture things that happen in the fleeting moments of life. The existentialist touch in your shots are often thought provoking.

Your feedback in the last post reminds me of the need to climb out of the little den that I have been staying in and to try something new.

Deadpan style ... interesting! Implicit in the way you put the term. Anyway, keep it open-ended to keep the ambiguity going and my mind thinking.

Do you still remember the stone-walled houses that serve, for example, as toilets, changing rooms, warehouses and staff quarters in Kowloon Tsai Park? They are still there now.
