Here is a great article about 'supercharging' your M 240 from 24MP to 96MB:

 

A Practical Guide to Creating Superresolution Photos with Photoshop

 

In a nutshell, take a lot of images while handholding the camera (no tripod) and stacking them in Photoshop to improve resolution and noise. This will not work with moving subjects.

I tried it yesterday and I was severally disappointed. The main issues are:

 

- Aligning was not perfect - even after trying all options. Some parts of the pics will align while some other part will be a pixel or two off. I shot handheld in burst mode. Finally I could find only 6 (out of 20) that I could use to align. I am using Photoshop CC

 

- After averaging the results are no better than simply upscaling 200% with nearest neighbor (same used in stacking). Some parts of the pic may look better at close inspection, some worse. It is all cherry picking.

 

- Forget about using it with any foliage. They move, creating multiple images in stacking and averaging.

 

- It took me almost 30min for one set !!

 

See the results 100%crop from stacking. I was hoping for the lettering on the yacht to become more clear. For now it is a fail for me.

 

(btw, its M240+35 lux fle shot at f5.6)

And now the original single shot upscaled 200% with nearest neighbor. You can see that it is essentially same for the yacht and so much better for foliage (no stacking of moving branches).

Interesting. I tried it today (on my m4/3 camera, not 20 images because it would take a few hours to process on my old pc). The results were interesting, in that very fine details of distant tree branches were slightly more discernable and distinct when viewed at 100%. Conceptually I think the notion of a vibrating sensor and imbedded software is the way to go....manual manipulation to achieve results is just too iffy, time and labor intensive.

Is it just me? It appears to me that detail may be enhanced, but transitions have been destroyed. Especially the boat shot: The stacked version (and I am ignoring the obvious foliage problems) looks like an oversharpened image.

errr...... the real questions is why ? ...... :rolleyes:

 

there is no affordable screen big enough with enough resolution to show them on ......

 

I don't have room for a 64" epson printer or 9k GBP to spare on one ........ or a bush shelter or billboard to stick the prints on.

 

Sorry, but it is basically a gimmick.

 

If you need industrial size images you need medium format or larger ..... and some sensible use for the output....

The problem is not that a 100 MP camera will be able to capture all those pixels, the problem is that you will never be able to squeeze them into your print....

 

The M8 with 10 MP often delivers good-sized prints that are as excellent as 24 MP ones from the 240.

If you downscale the 100 MP print to 25 MP, you will have a noticeably higher quality than a native 25 MP camera. Therefore this will help even if you produce small prints.

 

Depends on how small.

Depends on the lens and shooting conditions.

Depends on the software.

Depends on the printer.

Depends on the inks.

Depends on the paper.

Depends on the display conditions.

Depends on user technique and capability….at all stages…things could even get worse.

 

The camera is only a part of the chain…and maybe not even the most important for a small print, assuming good quality to start.

I don't need more pixels .....

 

I just need each one of them to have a wider dynamic range and better light catching sensitivity so higher ISO's are usable.....

 

.... and a camera with a processor powerful enough to do it all really quickly .....

 

(which is where Leica consistently lets itself down)

I had not followed this thread after posting my experiment...

 

Yes, the stacked picture looks oversharpened since I followed the instructions in the original link.

At the end it asks you to *optionally* apply smart sharpen. Without sharpening it looked very much like original enlarged 200% (I posted the enlarged boat pic as well). I was hoping that sharpening will give me better results, but it didn't.

 

Anyways, my conclusion was that stacking is not worth the trouble for more pixels. If I really want more pixels then I will shoot with slightly longer lens and stitch overlapping pictures. I have gotten excellent results with my 90mm shots stitched to cover 50mm FOV.
