Eos 400d ( Rebel XTI )

TomBStonE

let us imagine that for a series of photos you program the auto ISO beach between 100 ISO and 400 ISO but that for any reason you must take 1 photo in 800 ISO!

it would be then damage that to make a shot the AUTO ISO deactivates...

it is perhaps true that the automatic return in auto ISO is not perhaps the most appropriate solution.

In that case she I join Mirfak on the idea of the combination of key, by taking back a point which I tackled before, that is to say the quick activation of the AUTO ISO via the abbreviated menu.

In summary, the AUTO ISO would deactivate during the manual modification of ISO, and it would be possible to reactivate fast via the abbreviated menu.

AutoISO can now be (de)activate from the ISO menu (UP button): press DP and AutoISO is activated; select a value (press SET) and AutoISO is deactivated. To select a manual ISO value, you are going to enter the ISO menu anyway; and two keystrokes to go back to AutoISO does not seem a lot to me.

Mirfak

scrax mentioned that he would set AutoISO between 100-400, but I would end up using 100-1600. Because I shoot RAW + JPEG, the RAW files with ISO >400 clean up fine in post processing. Now the foregoing made me think of something... How about an option to switch to RAW *only* under certain conditions e.g. ISO>user specified value or exposure time >1s (when long exposure noise can be a problem). When I say "switch to RAW," it assumes that either JPEG or RAW+JPEG is originally set. On the other hand, it could be argued that there should be an option to switch to JPEG if the camera is set for continuous shooting.

Anyway, I think that AutoISO is such a big feature that after it's completed, a new feature release should be generated, and the user guide updated.

Sorry, I haven't tried this out yet, so the solution I'm thinking of already exists! Excellent!!! With AutoISO this easy to activate/deactivate, I really don't see the need for any additional special logic for this purpose.

Out of curiousity, how does AutoISO work with flash?

I tested 400plus build - 20110816 - r741

the combination of keys " ISO " + "DP" seems to me perfect.

Eduperez this combination is very good, good idea 😀

I also noted that the AUTO ISO worked with modes " AV " " P " but also with modes " M " and "TV".

I wondered how we alloy to know that the auto ISO mode was activated ?!
Whoa !!! you have already found solution with the word " auto « is displayed on the screen next to ISO; p

It is an very great work, thanks a lot 😀

Hi,

We've made some changes lately.
The AutoISO is returning and it is a great addition 😉
Kudos to Edu !

Another (not so big) change is the migration of the translations to languages.ini file.
All translators, please update languages in the languages.ini file and create an issue on the project page with the patch, or email me. Please update the translators info on the according section in the .ini file.

Please test and report bugs if found 😉

note: of course you will have to copy the languages.ini file to the CF card if you want additional languages.

scrax

Auto ISO now is perfect in how it's activated and deactivated from the iso menu, can't wait to test the new languages.ini

EDIT: I'm testing r750 and auto ISO seems broken now, It stay at min ISO we have set. Last working rev tested is r741.
languages.ini works good.

r757 working good. AutoISO too! Great, thank's Edu and 0xAF

Why won't auto iso max go over 1600? I like the new gradual iso stepping.

Hi guys,

First I'd like to thank all of you for the efforts on this model. I'm actually still enjoying my EOS 400D because all the enhancements made by so many of you.

I'm from Brazil and I like to contribute by adding the Portuguese language on the Rebel XTi.

Let me know, how I can help.

Cheers,

Marcus

Unfortunately the camera does not support this language (just like mine).
So far we are relying on the camera's language and you cannot have other languages than the build-in.
I was thinking to add "extra" languages to 400plus, but so far I haven't done it.
For now you can take the languages.ini file from here: http://code.google.com/p/400plus/source/browse/trunk/languages.ini
or from the NightlyBuild ZIP file http://code.google.com/p/400plus/downloads/list and add your language to it, then send a patch (or the whole file if you do not know how to send a patch) to us. You can open a new issue in the project page http://code.google.com/p/400plus/issues/list and put the file there.
As soon as we make the extra languages, we will post here and you will have the chance to test it.
Thanks for your support.

note: please keep in mind that the translations are only for the 400plus (the hack) and not the Original firmware itself.

Hello, my first post! I am excited about the AUTO ISO feature. I am not sure from the previous posts, but is the max Auto ISO configurable? I hope so, as limiting it to 100-400 is restrictive. The user should be able to select the Max, up to 1600. Please ignore this if it's already working that way.

On another note, The feature that disables the arrow buttons when your face is on the viewfinder (preventing the nose of left-eyed users from accidentally changing settings), has removed an important function for me. I routinely change ISO and AF without moving away from the VF. This change has eliminated this ability. Can this be changed to an option?

I am looking into how to submit an issue to the proper place, but I figured I'd start here.

Excellent work and thank you to all contributors!

relic38

I played around with the nightly build a bit, specifically Auto-ISO. I noticed some quirks in Tv, where it did not always adjust and went back to the selected ISO. I am not sure how to reproduce this, it just happens. I have safety shift on, if that helps. I have not seen it in Av or M.

Because Auto ISO use the base ISOs that are 100, 200, 400, 800 and 1600 to work like when quick scroll in the intermediate ISO menu.
I've already suggested to add 3000ISO (the max usable value) to the base ISOs but I'm not sure it can be done easily because (from what i understood from the source code) there are some maths involved to find out the intermediate values that will go wrong because 3000 is not 3200, hope it makes sense and please correct me if i'm wrong.

very happy to see AUTOISO function back.
I remember this thread was made by someone who wanted this future on his 400D. this seems to be the third serious try to make Autoiso. I tested the older version before (made by sergei), but it had problems. not working corectly (sometime the iso do not change) and it was to slow.

this third try seems the best. it's working fast, and it works correctly, so a BIG CONGRATULATION to eduperez for that. however a simple like this Autoiso is no better then a camera in Auto mode.

I WILL GIVE YOU SOME HINTS IN IMPLEMENTING A GOOD AUTOISO

You need to have some control over it to make it helpful for advanced users:
1) the possibility to set a maximum ISO for autoiso (like Nikon dslr have, and Canon 60D have)
2) the possibility to use only full stops ISO for autoiso.
the problem with xD, xxD, xxxD Canon cameras is that intermediary ISO is not by made hardware amplification. So Read Noise (Blackframe Noise) is bigger on ISO125 compared to ISO200. On ISO 160 Read Noise is smaller then on ISO100 but you lose dynamic range. So from my point of view is not a good idea to use intermediary ISO
see this http://forums.dpreview.com/forums/read.asp?forum=1019&message=19721647
Also on the 1Dx series is not a good idea to use intermediary ISO. Even they make those using hardware amplification, they use a second amplifier to make those iso. So on intermediary ISO's you have primary + secondary amplifier noise.
see this http://www.openphotographyforums.com/forums/showthread.php?t=4771
Only Nikon use hardware amplification on the intermediary ISO, and they use a single amplifier. So there you have no bad points on using them.

Also to make the Autoiso usable in different modes you have to put some limits in exposure parameters:
1) in Av mode you must be able to set a maximum exposure time (like Nikon have, or Canon 1DmIII, 1DmIV).
It is a bad idea to use a fixed exposure time as the limit to change iso (like Canon 40D, 50D have), because different focal lengths require different exposure time for obtaining unmoved images. Even linking the maximum exposure time to focal lengt of the lens (like 5DmII,7D,60D have) not think is a good idea, because for example maybe you want to shot a moving object in fast change lightning . So is a better idea to set this maximum exposure time manually.
2) in Tv mode you must be able to set a maximum aperture opening (like Canon 1DmIII, 1DmIV have)
For example you may not want to let camera chose F2.8 or F4 when shooting on macrophotography
3) in M mode you must be able to set exposure compensation (like Nikon have)
Letting the camera chose all exposure parameters is not a god idea because it can overexpose or underexpose.

Perhaps you should check AutoISO on 400plus again, as most of those features are already implemented (in fact, all but the last one).

Having exposure compensation (EC) in manual mode when AutoISO is active makes sense. Normaly, this isn't required because the user has full control of shutter speed and aperture, and ISO is fixed. However, AutoISO compensates to provide a "correct" exposure (per the camera meter) and thus EC is required when the meter is fooled by lighting conditions. The issue of course, is that both EC (in P, AV, or TV) and aperture control (in manual mode) use the same button.

This is already planned (the algorithm for this is quite simple), but as you mentioned, the problem is in the buttons; we will probably have to use LEFT/RIGHT while at the viewfinder for this.

Hi everyone! I can help translate the file "languages.ini" in Russian, should it? and how to do this?

This problem make me think to a feature that I was thinking about.
Scrollwheel function switchable in M mode with Av button.

Camera starts with Scrollwhell set to change times,
pressing Av once makes Scrollwheel change Aperture,
pressing Av for a second time makes scrollwhell change Exposure compensation,
pressing again Av for a third times goes back to the default (Scrollwhell changes times)

and if possible we need to think to a way to show in what mode we are,
maybe just underline the value that will be changed by the scrollwheel.
