hi,
would it be possible to implement manual or smaller iso steps (like in
5d) and manual color temperature selection or creating own presets?

Manual ISO steps: yes, I already have a working example.
with a little glitch: ISO 320 is displayed as ISO 400 in the shooting
screen (and so on), but in exif is 320. I didn't check noise levels to
see if it really works.

Color temperature: maybe yes, maybe no. Presets with green-magenta &
red-blue, maybe yes. This needs some experimentation.

Manual ISO override works in video mode, too, except ISO 12800.

It seems you can set even higher values than 12800, but pictures come
out with ugly bands. I thought I've just fried my sensor... but it's
alive :)

So... I've taken a pic with ISO 102400 displayed on exif, and another
one with iso 10000. Both came out with horizontal or vertical bands.

Anyone wants to play this? It might be risky, but if you like the
idea, I can prepare a test build.

Iso 8000 (raw value 122) is also fine. Next value (123) is also
displayed as ISO 8000, but causes ugly bands.

Has anyone done similar experiments on the 5D2?

Alex,
ISO 102400 is kind off cool. Do you the image taken with that? Maybe an effect can be used for an artistic shot..

Here's the artistic shot (cropped due to file size... it had 13 MB)

Here are the other two "artistic" shots. Also cropped, but with Exif info.

Ideas?

The good news is that all the codes from 72 to 122 can change ISO in
continuous small steps (which means 50 ISO steps in the range
100-8000). Not bad for timelapse.

Here's the rough correspondence between ISO values and raw codes sent
to the camera (to be viewed with monospaced font):

//~ const int iso_values[] =
{100,125,160,200,250,320,400,500,640,800,1000,1250,1600,2000,2500,3200,4000,4500,5000,6400,7000?,8000,
bad, ???, ???, ???, ???,12500};
//~ const int iso_codes[] = { 72, 75, 77, 80, 83, 85, 88, 91, 93, 96,
99, 101, 104, 107, 109, 112, 115, 116, 117, 120, 121, 122, 123, 124,
125, 126, 127, 128};

Code for setting the ISO:
static void
iso_toggle( void * priv )
{
unsigned * ptr = priv;
*ptr = (*ptr + 1) % 150;
if (*ptr < 72) *ptr = 72;
lens_set_iso(*ptr);
}

And an experimental build is attached. This build might fry your
sensor (but it didn't do any damage on mine... yet), so use it at your
own risk. As with all Magic Lantern builds, if it breaks, you get to
keep both pieces.

Usage: Shoot menu -> IsoOverride. You can set raw values between 72
and 149. Values higher than 122 will result in "artistic" shots like
in previous mail (but some of them may work well). In live view
(preview only), all values seem to work well ('cause exp.sim
uses.different code than actual shooting).

Code for this test feature is also attached (clone the latest sources
and paste shoot.c over the old one).

If you try it, please share your findings here. Thanks.

I'd like to know the correspondence between raw value & actual ISO
value. Exif will display a rounded value (100, 125... etc.) but the
histogram shows that the steps are smaller than that.

Any idea what segment of memory gets updated when the colour
temperature is changed in the 5D2 ? Maybe we can look at what the 5d2
does and then look for something similar in the 550D code. I assume
the 5D2 has manual colour temperature in video mode... the 7D does.

In 5D2 there is PROP_COLOR_TEMP. AJ can help us with details (address,
possible values...)

GCC automatically removes functions which are not called from code...
so the chances of fixing this by simply changing the value of this
property are small.

With almost linear interpolation (or.. maybe it could be called
psychologically linear interpolation), the correspondence between raw
value and iso could be:

//~ const int iso_values[] =

{100,110,115,125,140,160,170,185,200,220,235,250,280,320,350,380,400,435,470,500,580,640,700,750,800,860,930,1000,1100,1250,1400,1500,1600,1750,1900,2000,2250,2500,2750,3000,3200,3500,3750,4000,4500,5000,5500,6000,6400,7200,8000,


bad, ???, ???, ???, ???,12500};

//~ const int iso_codes[] = { 72, 73, 74, 75, 76, 77, 78, 79, 80, 81,
82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98,
99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112,
113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126,

Raf was able to take a picture with ISO 25600, raw value 136. I've
tested it and seems to work :)

My theory re the "artistic" shots:

I've seen Philip Bloom remark that some ISO's seem noisier than others, and that 160/320/640 seem much cleaner than others. He refers to them as "native".

I presume we have some "coarse" adjustment possible at the sensor, and then the "inbetween" ISOs are achieved by just applying gain to the sensor data. The "artictic" shots must be when we drop to almost-no-sensitivity plus lotsa gain.

Also, related note: can we get any speeds BELOW 100? I hate lugging the Fader ND around to shoot 1/50th in sunlight (but I admit that ISO 25 or 12.5 seems optimistic)

is it possible to display the iso value in the screen again? like in
the beggining when e have the iso, shutter and iris...

Below 100: 70 and 71 were interpreted as Auto ISO. I didn't try lower values.
ISO value displayed: yes, but this needs some code changed.

Not sure if this applies to the 550D but for the 5D2, the cleanest
ISOs are 1/3 stop down (160/320/640 etc) from a true ISO step
(100/200/400/800 etc). This 1/3 stop down reduces dynamic range and
with it the SNR thus giving a less noisy image. On the other hand, a
1/3 stop up (125/250/500) increases this gain and thus increases
noise.

On the 5D2, ISO 50 is not "native", it is a processed stop down from
exposure taken from ISO100 and thus reduces headroom and DR. It
wouldn't be advisible shooting anything below ISO80.

With the new ISO hack, would be fantastic if someone can test whether
this applies to the 550D too.

Alex do you think it would be possible to lock autoISO maximum values and prevent it to go over 1600-2000 ?

I'll take a look. I'd also like a better Auto ISO algorithm (CHDK has
a nice one, but for me, one with min shutter speed is enough).

Anyway, I've just shot some Xmas songs today. ML helped a lot (zebras
& manual audio) but here's what I've missed:

* Manual audio controls is good... but it could turn the volume down
automatically if it detects red peaks. But don't turn it back up. I
think it's best to turn down the digital gain. I've missed the first
song while trying to figure out how to turn the volume down.
* Auto HTP. Turn it on when it detects overexposure, turn it off
otherwise (and maybe turn on ALO). Do this only when not recording (or
maybe a shortcut key is enough).
* Panini cropmark

Someone asked me: what's that blue thing? motion detector? /* he saw
the zebra in action :) */

Could you make even smaller ISO steps like it was previously so we would
 have more options than 7D/5D ?

100,110,115,125,140,160,170,185,200,220,235,250,280,320, etc

That would be perfect

So about white balance,is it possible to force kelvin values to set
white balance by numbers like in eosmovrec software or like on 7D ? Or
to save white balance presets in MLantern menu ?

This needs some more investigation of the firmware. Custom WB data is
not stored in properties (0x8xxxxxxx). Instead, WB mode and WB
shift/bracket are stored in properties.

looks great, 2700K looks correct, but 10000K looks more like 5000K. What does 10000K look like on your camera?

Can you test with 7D or 5D /60D and tell what should be what so it could be corrected properly ?

On my camera, at 10000k, white looks yellow. At 2700 it looks blue.
How it should look?

It would be helpful to check (with Debug->prop_draw) which properties
are changed on 5D2 or 60D when you modify kelvin white balance from
menu.

On my friends 7D, 10000K looks like orange almost, like everything in the frame will be yellow-orange, except a dark blue sky, which looks white. I'll do dome more testing, it may just be the light I have access to is so cold already.

That is how it should look.
Assuming your light source is somewhere in between the two, and your
white reference object is... well.. white.
The question is, how accurate is your calibration?
Comparing shots (and Properties) against a camera with custom colour
temperature settings, under the same lighting conditions is probably the
right place to start looking.

But if you're curious; http://en.wikipedia.org/wiki/Colour_temperature
has some examples of the colour temperature of various light sources.
Your white reference should look similar under all these lighting
conditions with the colour temperature set appropriately.

1,700 K Match flame
1,850 K Candle flame, sunset/sunrise
2,700�3,300 K Incandescent light bulb
3,350 K Studio "CP" light
3,400 K Studio lamps, photofloods, etc.
4,100 K Moonlight, xenon arc lamp
5,000 K Horizon daylight
5,500�6,000 K Vertical daylight, electronic flash
6,500 K Daylight, overcast
9,300 K CRT screen

Can you shoot some test frames with both 7D and 550D (same scene) and
post them for comparison?

I will try to do that tonight. I'll do some tests with those objects Morgan mentioned. I have a color/gray card I can put in as well.

On the 5D II you get a white balance range of 3000 - 7000 Kelvin on
Auto and 2500 - 10000 Kelvin on the custom Kelvin setting

I thought I copied the footage from the 7D to my card, but apparently it has been corrupted. However, while recording the tests, both cameras looked the same. I will try to get the footage online tomorrow.

Latest build (my battery just went dead, so it's not fully tested).
The other battery is home, charging.

Kelvin WB can be set from 1700 (in theory, I wasn't able to test this).
New feature: a third mode for ClearPreview (always). It removes all
the overlays from the display. Zebra & friends are still visible when
you use the Q menu.

This was tricky to implement, so please stress it and report all the bugs :)

Look in the archive for updated docs.

Would this also hide the on screen stuff for say video passthrough when not recording? Then we can send 1920x1080 out hdmi? not record? but say record on an ext device?

WB in Kelvins is from 1700 ,probably can be even lower , pick ClrPreview to Always

a 1080 interlaced or better a progressive signal out of hdmi, would be
nice to record without compression on a third party device like
nanoflash. so you could probably record a raw full hd signal!
if you put an external monitor on hdmi, normally it is sent a bad
1080i signal, with all the signs you see on the screen. when you press
the record button on the camera, on the 5d and 550d the signal gets
downscaled to 640x480 i think.
so maybe there is something possible!

Yeah i would love to just have it hide all onscreen stuff incl the
record dot. So we can just record to a desktop/laptop or flash device.
