Eos 400d ( Rebel XTI )

[paten]

 I didn't see that problem until i pulled the battery out. To clear it, i had to turn AutoISO off and on. Print button in M or TV mode will clear it too.

Hello, I did pull the battery out, put it back in, and now it works. Great!
By the way, when your firmware is running, spot metering does not work in AV anymore, but only in TV.

yeah i have the same problem, but not a big prob i think,.

I tested this release and did as you wrote. I set Max ISO to 800 for example (Contrast = 2, Saturation = 0), went to P, back to Av. Display showed ISO 800. Then I metered on something bright, ISO on display switched to ISO 100 as it should. But when I take the photo, it shows ISO 800 in the review. I think the saved ISO is wrong though (versus the real ISO of the picture), since the shutter speed and aperture in the saved photo are as metered just before taking the picture, only the ISO is at 100. But if ISO were really 800, to photo would have been overexposed.
When I meter on something dark, ISO does not go beyond 800, so this part works.
I hope this can be of any help.

Just small fixes in AutoISO:

Sergei,

What are the changes? I have installed but see no differences

[Sergei]

Spot meter  icon was not showing on the screen after power cycle, and sometimes AutoISO was locked to highest ISO after CF card  reinsertion.

Good work sergei! How about putting everything in a menu like on the 350d?

Hi Sergei,
first of all I would like to thank you because your work is superb!

I'm sorry but I'm a bit confused about available options...
For example I cannot get any ISO lower than 100 but I cannot remember why... 
I would like to write down a minimal (really minimal) instruction page.

ISO change: normal ISO select, then sub stop regulation with direct print
Autoiso: use "Shoot w/o  CF" option, ON=auto-iso OFF=manual-iso
Spot metering: In metering mode selection highlight Evaluative and press direct print
AF group schemas:  rapid double push AF-Point and then change schema with direct print button
   
Autoiso maxiso..... sorry here I'm lost (surely my fault)
If we get that simple text file it could be put into source archive so anyone can get it updated anytime.

I' here to prepare it also if you would and you like the idea...

Bye...

[Sergei]

    Auto Exposure Bracketing:

   Go to menu,
   Picture Style,
   Select User Def. 3 and press jump.
   Set Color tone value to desired AEB:
      -4   +-2.3EV
      -3   +-2.7EV
      -2   +-3.0EV
      -1   +-3.3EV
       0   +-3.7EV
       1   +-4.0EV
       2   +-4.3EV
       3   +-4.7EV
       4   +-5.0EV
   To enable(disable) AEB go to "Drive mode" menu and press print. Blue light means enabled, red - disabled.

    AutoISO:

   To enable AutoISO go to "ISO speed" menu and press print button. Blue light - enabled, Red - disabled.
   To set maximum ISO, change contract and saturation values in User3.
   Contrast values:
              -1 100
               0 200
               1 400
               2 800
               3 1600
               4 3200
   Use saturation values from 0 to 4 to set how many times you want to increase main ISO to the next higher value.
      Example:   contrast 2 and saturation 1 will set ISO 1000.
     Then switch to Tv or M mode and back to Av or P. You will see your max ISO as ISO value
   Minimum shutter speed can be set from Tv or M modes. Shutter speed in those modes will be minimum set point
        for Av and P (after switch from M or Tv to Av or P).

       ISO 16,32,40,50
          "shoot without CF" ON

Very good work, Sergei, but it's confusing and not "photographer friendly" I think the next step will be to fire up a NEW menu just pressing the print button and put all settings there.

[Sergei]

I will, if I find a way to do it.

[djs]

Fantastic work !
Congratulation !

AutoIso work fine and so good to have possibility to set max ISO
No news about calculation of AutoIso with Focal length parameter ?

Thanks you

[BTP52]

Thanks you from BTP

Hi Sergei,

thanks a lot for this great work!
The new AEB-parameter are exactly what I was looking for. Really, really lovely!

It will be very good if you manage to do it.Fantastic job thank you:)

[Sergei]

Does anybody know if address  0x16B60+0x28 is NVRAM? ISO value stays the same in that location even after batteries was out. I'm thinking about how many writing cycles it can handle because of AutoISO updates ISO so frequently.

Many thanks for your great jobs!!

Is it possbile to enable the support of TTL or A-TTL External Flash in 400D?
