Any brave soul dare to push 3-4 stops b&w shots on both M9 and M? (picture thread)

My another thread failed more or less. Too much letters there.

 

Now I'm looking for truly brave souls to push raw files from their dear cameras. Continuous life of cameras or users are guaranteed as far it involves 4 push stops! No heart strokes or such. I believe that sensors are still warranted, I've asked Leica and got their permission.

 

I hope to see some pictures. You will get awards for the unimaginable bravery!

There are RAW files on the web, why don't you download and make your own side by side comparison. From memory Digital Photography Review is one website that provides samples. They usually shoot same scene (for years) to illustrate sensor performance at different ISO, usually RAW & JPG files are provided.

 

There could be other websites, some google search can take you faraway.

 

Also on LUF http://www.l-camera-forum.com/leica-forum/leica-m9-forum/275508-new-leica-m-vs-m9-daylight.html

 

BTW, I use M9, happy with it in all its limitations. Tried new M, it is different and much better performing sensor for higer ISO shooting.

This brave soul has no M9 i'm afraid so i'm sorry not to participate to the tortures you intend to inflict to this poor camera.

The result will of course depend on which ISO that you used when you made the image. Here is one shot at ISO 320 pushed 4 steps and converted in SEP, neutral. It is of course overexposed now in some parts, but it was one of the darkest files that I had. If you do this on a file shot at 3200 you will have banding already after 2 steps. This is the M, I have already sold my M9.

thanks for the link, I've seen this before but I didnt found -4 stop underexposed images. Maybe I missed somewhere

We should create S&M section for Leica users.

I'm impressed! I like the result. No banding or weird behavior as I could detect.

 

If you have time some day, please make a test shot iso 1250 pushing and see if banding happens. My Rd1 shot at iso 400 already expose banding by 4 stops push. In Mallands thread, M9 seems do well at iso 640 pushing 4 stops.

 

Thanks in advance!

I thought you wanted us to compare M9 to M240. I did not do serious tests but pushing the M240 by 4 stops from 200 iso looks like direct 3200 iso at first glance. Here three sample pics including the original one and the same pushed by four EV in colour and BW.

Thanks a lot this is a very intersting test. Could you please do a similar test for long exposure, ISO 200 and 60 sec? Unfortunately, the M240 allows only 60 sec for ISO 200, so underexposure by 4 stops and pushing in photoshop is the only way get ISO 3200 and 60 sec ( as far as I know at 3200 ISO the shutter closes already after 8 sec.)

I have no tripod with me here sorry.

Here's a 1250 iso file pushed by 4 EV in color and BW.

thanks, lct. I appreciate it!

 

I dont have to do comparison, only see if it is acceptable. I do like some grain

 

I will check your files, it will take a while (slow internet)

[lct]

If you have nothing against digital grain, just add a bit of it and banding will vanish for the most part. One click in Silver Efex here. Not that bad at 20,000 iso.

I looked at it closer and noticed a strange thing. there is lots of small rectangulars everywhere.

 

is it normal for cmos, is it that banding you, lct & stickan1 thinking about?

 

it is something new for me and I dont know if I'd call it as banding when it looks very controlled. I agree that little grain at iso 20 000 is impressive. We dont need MM?

Curious indeed. I don't see that on mine.

The rectangles could be related to this phenomen...?

[lct]

They are not in the photo. See my 100% crop above.

[jaapv]

It must be something in Tomasis' browser.

Vanishing banding with Silver Efex. Same 100% crop.

Are you using photoshop with pixel grid selected in- view show menu pixel grid ?

[sblutter]

Fabulous results - thanks for sharing. Love that discoveries continue to prove M9 is truly in the tradition of M3 > M6. No video nonsense etc. - and now more than ever, very low light.

 

And for all you monitor pixel peepers - these would print up far larger than you'd suspect and be worthy of exhibition (technically).

 

Will add Silver Efex to my tool kit - thanks for the info!

[lct]

Zero chance that M9 can do that i'm afraid. Very good camera though. How often did we use more than 800 asa in the film days? Now we are spoiled with the M240. I now use 2000 iso the same way as 400 asa in my youth, which opens new possibilities.

Hallo,

Look here: Leica M

[tomasis7]

nothing wrong with my browser or photoshop. it is real one in photoshop file.

 

I think it is banding, right lct? though it looks very controlled. interesting how silverefex is able to remove all this. Do you see this rectangular mosaic without filter, "raw" jpeg file?
