Thank you Sergei! You were very fast!

Only way i know how to display iso in info bar is to change actual shutter speed. With a flash opened shutter cannot be higher than flash sync speed, which is 1/200. This autoexec.bin will not set shutter to 30" or to bulb, but it will show 200 for ISO when flash is opened.

Just some wishful thinking, but... could it be possible to temporarily deactivate the flash, show the ISO (i.e., change the shutter speed), and then revert the flash (and the shutter speed) back to the previous state?

Sergei

Thanks eduperez. Never thought about it.

@eduperez
I would know exactly how to use the internal flash compensation -4EV -6EV and get benefit. I don't like very well the effect of the internal flash so I would like to know where you prefer to use -4EV and more, maybe in the portrait? If yes how? Thanks in advance for your suggestions.

@Sergei

I would like to propose another change:

if I use the flash compensation with values greater than +2 or -2, in the exif is not reported the exact value but is reported 0. You can correct this little problem or is it impossible?

Thanks again for your time.

Hi Riccardo78

Thanks. Tested , but with this not good. 🙁 Do I ruin something? Is it necessary to function in the menu to be ISO visible in the viewfinder?

Kekk_400D

Attila, you need to set the "Show ISO in the viewfinder" to On. How? Press Menu, than Disp et voilà you have a new submenu. With the up/down arrows search the "Show ISO in the viewfinder" and with the right/left arrows set On. Than press Set in order to memorize your setting.
Try, it's easy.

Hi
I did it already... Does not show... 🙁
Is difference between machines?

Kekk_400D

Remember that it runs only with Tv or M. When you see in the viewfinder, see at the time shown inside: clicking on the arrows you will see time, ISO, time, ISO till you press the arrows.

Tested with internal and external flash. DPP and firefox shows correct value. Does it report right value when you view image in a camera?

Kekk_400D

Hi Sergei and first of all thanks for your job. I saw that with the "b" version the EXIF value for the Compensation Exposure in DPP (ctrl+I on a RAW image) Flash was at zero while in the camera it has been set at -4, for instance. I didn't try with the "c" version, I'll be try tomorrow and let you know.

Attila

Hi Sergei

ISO 80,50, etc, would be able to work?

Attila

Kekk_400D

Ok Sergei, "c" version is ok for DPP value "Flash Exposure Compensation". This version is very useful and stable.

I agree!! Excellent job.

"c" rel. is perfect!!

Hi to all of the users of this forum.

I am also an XTi user and a user of the CHDK developed by Sergei et alter.
I have succesfully tested several versions so far and I find them very usefull.

Ther is now just one thingh I cannot make work: the show ISO in viewfinder.
My Xti is already running firmware 1.1.1, autoexec version 13c, and I have tried the function both in M and Tv mode, after having enabled the "show ISO" in the new menu which appears
after having pressed Menud and Disp.
When in Tv mode ( or M mode ) if I press either left or right keys, what I get is the activation on the
LCD display of the choice of the Metering Mode or the autofocus mode, and not the display of the ISO in the viewfinder.
I am sure I am doing something wrong, but I don't understand what it is.
Maybe something related to a different setting in Custom Funcions.
Is there anybody there who can help me understaning what's wrong ?

Riccardo78

You have to bring the eye to the viewfinder ...

Sergei: please take a look at the 550D... it's a mess right now.. I wish to have it like my 400D was 😀
