These are compiled with the most recent cr2-hdr histmatch-3 I think. Tell me what you think!
Amazing how It got the branches so well!
This one would be a complete silhouette without a 400/3200!

Too big... one sec
Good footage doesn't make a story any better.

Go to upload.ee and once you upload take the BB code directly from there

Thanks @painya!

I honestly thought Flickr would get the job done but their BB code wouldn't just work on this forum or maybe Im doing something wrong?

I'll use upload.ee for now although it only stays on for 120 days.

Thanks again.

One of my first shots with dual iso...  The shadows were moving, so long exposure was not an option. Dual-iso worked verry well.

Great shot Blade!

Here's another 100/1600 Dual ISO I took of her outside in the dark...

One of my dual ISO favs shot on the 50D + an old 28mm M42 lens

Dual ISO 100/800 (8 shot stitched panorama)

The shop is located in a dark alley. (click for larger size)

Dual ISO 100/800 (8 shot stitched panorama)

Why do you dual_iso a static scene - to save shutter cycles, or to save time on the whole pano? Strictly speaking this would be a scene for traditional bracketing which would give you lower noise and higher resolution in shadows/highlights.

Bracketing might be the traditional way to do things but ...1. No tripod with me 2. it took about 10 seconds to shoot 3. Dual ISO = less card space used (compared to 8x bracketed shots) 4. I was out shooting video that day 5. one less step in post (HDR merge) ;)

Most of these shots here look really great, I don't know why but every-time it I give dual ISO a shot and use it together with the ETTR function (I lack the estimation of setting the split ISOs myself) my shots just tent to turn out extremely underexposed, often beyond recovery... this might be because I mostly tried in interiors where there might be too much difference between high and low lights, or it is simply too dark for a slowest shutter speed of say 1/60 for handheld... anyway these samples make me a bit jealous!

@Africashot - It's more luck for me. I tend to not use auto ETTR. I snap a few shots and if the preview looks very slightly over exposed I know I'm in the range. If they look dark I adjust the settings.

Thanks! That might be a better way to go... I am so inexperienced with Dual ISO I was actually under the impression the preview wouldn't tell me much about the final image, also I thought it would probably be easier to recover shadows then highlights in this case, but this sounds like the way to go, I'll try it as soon as I get a chance!

Last bit of shooting its been pretty good, esp outdoors. I set minimum to 1/60 or like 1/250+ (driving), clip green... also the raw histo will tell you where you are in terms of ETTR so something like +/- 1 is alright without auto.... I also noticed the preview seems a lot darker than the shot when imported to light room. I was thinking a bunch of shots were way worse and then pleasantly surprised when editing.

Then again sometimes it will take a shot with bright light and  blow the hell out of it... I had this prob on waterfalls most noticeably, indoors it would occasionally pump the ISO up too high ignoring that I'm shooting a well lit subject for the background. Not sure if changing metering mode helps, it didn't seem to. So I'd have mad motion blur of something moving on a stage but the darkened background lit to daylight levels (bleh!)

When dual ISO was picked it usually made sense though unless it did the flip flop like 800/100, then my shot turns out half res for 90% of the pic and really dark, needing +5 in LR.

I.e. wtf did AETTR+DUAL do here:

How did the previous shot (3284) look like?

If it was slightly overexposed, ETTR maybe didn't know how much to go back, and just underexposed by a large amount (so the next picture, 3286, should be pretty good).

Some pics from me too (100/1600, ETTR):





Same pics from ISO 100: [1] [2]

Raw files: [1 iso100] [1 iso100/1600] [2 iso100] [2 iso100/1600]

Blending info (I used this script):

Code: [Select]
raw/2151.DNG:
--temperature=5000 --green=1 --saturation=2.5
    midtones: brightness level  7598 => exposure +0.75 EV
  highlights: brightness level 36122 => exposure -0.50 EV
     shadows: brightness level   245 => exposure +1.68,+2.62,+3.55,+4.48,+5.42,+6.35 EV

raw/2157.DNG:
--temperature=5500 --green=1 --saturation=2.5
    midtones: brightness level  3319 => exposure +2.12 EV
  highlights: brightness level 44011 => exposure +1.24,+0.37,-0.50 EV
     shadows: brightness level    61 => exposure +3.16,+4.20,+5.24,+6.28,+7.32,+8.36 EV

The improvement from 100 to 100/1600 is smaller than I thought; I can barely see any difference when looking at the pics on the monitor without zooming. Guess I should try something a little more extreme :D

Looked to magenta for me.  The color noise is a killer  :P



The differences in the dual-ISO shot will be more apparent if your printing large.  There's lots of detail in the shadows also which helps to hide the noise.

Hi all.  First of all I want to thank the ML team for coming up with such a wonderful software.  I have been a long time Canon user experimenting with Nikon at the moment but very soon I will be buying Canon 60D or 7D.  I am still in the decision process.

I wanted to ask about something that got me somewhat confused.  At the first few posts of this thread I remember reading "Dual ISO" feature was only available to 5D Mark 3 and 7D cameras.  But I saw Dual ISO pictures from 60D and even 50D cameras.  What am I missing exactly?

Main reason I am asking this question is buying a 60D is easier for me than buying a 7D.  I have used both cameras before and even though I want to buy the 7D my budget may not be able to afford it and I want to make sure I'll be fine with 60D.
