G9 High Res Mode

Fantastic detail, great shots. What a cultural and artistic treasure. Destroying that would be unimaginable, as if someone said they were going to destroy....................DPReview! It could never happen........ Has the FHJC put a lot of effort (unlike Amazon) into finding a home for it? Do you know the price?

Honestly, I contacted the FHJC for permission to go into the Sanctuary to take these pictures, which were taken on 9/15/2022. The last I heard they had not found any organization that had enough space (vertically) to install and display that ark decoration. That was some time ago. At least I have a 32" by 24" print of that in my computer room. If indeed it is destroyed I will share my picture with Jewish Museum or any other organization that wants to display it. I just wish I had the guts to move some of the things on the bimah (the stage), but I didn't. I just took the picture as it was.

I remember playing with that technique but could never get good results. It could be either due to the limitation of the s/w I used, or not enough understanding on my part how to do it.

That was in the days before 24MP became the standard resolution in APSC cameras.

Very interesting results. When you want to depict a scene in an abstract way, by reducing the color saturation, and making it look like a water color painting. Definitely has its charm in some situations. I can think of some of my photos of street scenes which would be good to present this way.

Beautiful work of art, and excellent detail in that photo.

For hand-held super-res stacking, software needs to be able to rotate images when stacking them due to "roll" between exposures, if it going to do a good job, and that is just as true for super-wide-angle as it is for long lenses.

Even if software does that optimally (or the camera doesn't roll), you need more shots hand-held than with sensor shift, because some of your shots will be near-duplicates of others, which will decrease noise, but not increase spatial resolution much.

Lots of shots and lots of computation to get significant increases in resolution.

Don't expect this method to work well with slow-rolling shutters with long lenses, either, as there will be different distortion in each frame. Correcting that would take even more computation, if software even does it.

It was called multi-image super-resolution as mentioned here:

I tried it too with my low-resolution Sigma SD9 camera and found it slightly OK but not enough to make a habit of it.

In theory, that camera should be one of the very best in terms of relative "gain" per extra image. Of course, if you value the pixel-level "look" that a sensor with huge pixels, no AA filter, and no microlenses gives, then you will lose that "look" with super-resolution, even though resolution is improved (and aliasing is reduced).

My main reason for not making a habit of it was that I only view that camera's 2268x1512px images on my 1920x1200px monitor. I only zoom in for the purposes of quality analysis and I don't print.

Others might ask "what about if you upgrade the monitor?" to which I would respond that my existing monitor at my normal viewing distance already exceeds my visual acuity - the which is around 0.7 mrad.

I don't zoom into images "to see more detail" as such ... an ant on a tree tens of yards away will remain invisible unless I mount a huge lens and use an heavy tripod sitting on hard concrete.
