I could have SWORN at one point I had my 70d configured with such an option that, in manual mode, I could hit a button and the exposure would snap to auto-settings. For example, I've got a scene properly exposed at iso 800, 1/250th, and f/1.8. The lighting changes, suddenly requiring 1/50th. Ideally, I go change sensitivity since I've got a few stops of headroom, but I don't have time just yet and want to "just get the shot" before I go chimping for optimal settings. I can just hit this magic button and the shutter speed will snap to 1/50th, and after seeing the properly exposed but blurry image, I can then go fix my settings. Does something like this exist in this module? Am I looking in the wrong place?

Case in point: I was shooting a concert, and leave my camera in M mode. I pick it up the next morning to get some snaps of a dog jumping on my friend, and all of them are way over exposed because I didn't have time to adjust settings. Sure, I could have switched to P, but I don't usually want to be there anyway. I'd rather have the reflexive workflow of auto button>(shoot?)>fine tune>shoot.

This is already kind of a thing in live view with this plugin - Half pressing the shutter auto sets exposure, but if you don't give the half press time, the shot uses the prior manual settings. But looking through the mirror, it's full auto all the time.

noob here first post.
Thanks for all the amazing work!

2 feature ideas:
1 add is to ramp. A dropdown with 3 options sunset ramp and sunrise ramp no ramp.  Basically a one way  falling light or raising light.
If sunset is selected and it ramps up to 800 iso it does not skip back down to 400.  Or shutter jumping between 0.4 and 0.5. 

2 Also saving curve profiles would be sweet!

Again thanks for all the work that has gone into this project!

Hi,

first of all, this module works on 1200D! That is really really great since it normally underexposes in low light.
Now, it does not work in Av mode, as far as I can see, seems by design. As an Av-in-most-situations shooter, I think it can easily be extended to do so.

Basically, if AV range (both limits) is set to Av value, the result is great. The benefit would be that it can be changed on a dial, without diving into ML menus.

So, as far as I can see, if (in Av mode only) these limits are set to Aperture value, thing would work like a charm! (Tv might be similar, at least as far as the lower limit is concerned)

Anyway, the module as is is one of the most helpful when it comes to stills. Now 1200D does what I wnat it to do better than 80D. Which reminds me...

Hi all! Newbie here! :-)

Have just installed the latest nightly on my 5DII and when the Auto Exposure module is loaded the aperture, shutter speed and ISO are flickering all over the place, any ideas?

Thanks and keep up the amazing work ML Team!!
