Thread photos dual iso
« on: July 30, 2013, 09:05:45 PM »
A thread to share photos taken with dual iso. If you want to try and learn how please enter this thread here. http://www.magiclantern.fm/forum/index.php?topic=7139.msg62864;topicseen#msg62864

Some more examples of what dual iso can achieve. The shadows pop out like never before. Mostly used interval between 100-1600 and ETTR to find exposure settings. Works perfect most of the time. From a visit in Copenhagen. I used a 5d mark 3.

*updated with more pics and with 900px width, maximum forumsize.

Thanks for the quick reply :-) This is another really clever addition to ML. Happy snapping...

5DMKiii and 7D only due to the sensor.

@Danne, Fantastic samples, great to see before and after,

Nice samples. Did you use 5dmIII or 7D?

Lovely picture! 14mm wideangle? What settings were used? Nice dynamic range :)
By the way. I got a warning before about too big pics. Think the max wide pixel size is 900px.
Thanks for posting

Would be very nice if you can upload some DNG files (or CR2 if you still notice aliasing artifacts).

@audionut. That is s beautiful picture. The light but too have those clean shadows really makes a massive difference. What settings were used?
@Alex. Will see what I can find. This function you created is unbelievably good when taking pictures.
Huge thanks

100-800.  I like keeping midtone resolution.

And sorry I moved my OP.  Check over in the dual-ISO thread.

No prob, moved mine as well.
Will check in about the midtones. For now I,m all over the intervals trying to push it and see what ettr comes up with when doing its magic.

My first test:

ISO 160/3200
Canon 7D
Canon 10-22 @10mm
f/8
1/320
ETTR + UniWB
Processed in LR 5



100% Crop


I'm going to make more shots in the next days.

Some tips:
- 160 is just 200 darkened
- on 7D you don't gain anything above 1600 => try 100/800 or 100/1600, but not more
- UniWB no longer makes sense, because you have raw zebras and histogram

Good tips.

I know ISO 160 is just 200 darkened, I used 160 because of the known vertical banding issue on 7D, while extreme recovering the shadows. It's weird, but you get less vertical banding on 160 rather than on 100 or 200, I don't know why, it just works for me.

I'll still try raw zebras and histogram, Dual ISO was my first ML test EVER : )

You get banding with dual ISO? Can you upload a sample?

I'll test it tonight and upload the tests. I'll test ISO 160, ISO 100, Non-Dual ISO and Dual ISO.
