I've read that ev won't work properly under manual.

Is it best to use the other modes, or stay in manual?

Been trying to figure out why my iso was fluctuating with ev and then all underexposed when locked the iso with all manual settings.

Been reading up on ev vs everything else and still having a hard time grasping it. If anyone has a good analogy please tell me.

EV (exposure valuation) or in the canon world exposure compensation is used to add or subtract light from your image. To accomplish this the camera will adjust one of the following settings; shutter speed, aperture size, or iso settings. When you shoot in manual mode you are in control of all of these functions, adjusting to balance the exposure, depth of field, and freeze to motion of your subject. In a sense you control everything including EV.

I shoot manual and use auto ISO, this allows me to select the depth of field, freezing the motion of my subject, and achieving proper exposure. You can still use EV with this setting, the only downside is high ISO when shooting in low light situations.

Keep shooting and postings!

Thank you sir!

I think using any setting except manual is too complicated, even the focus. Always used it in manual and when I started seeing the meter too dark then the iso fluctuating way too high I went back.

 

Would there be any point where those settings would be useful? Sounds tedious.

I set mine to auto ISO with a ceiling of 25600.
I use manual mode so I am in control of DOF which is REALLY important(the most important actually) and the shutter speed I want I order to freeze action, or intentional wing blur etc.
Yup, when I use EV it affects ISO, but when lighting is tricky/low I would rather get the shot instead of compromising on shutter speed and fstop. I pretty much refuse to be a slave to ISO, yes I keep it low as possible but NOT at the expense of making the shot.

In Aperture Priority Mode ( A on Nikon / Av on Canon ) Exposure Compensation ( the Ev thingie ) changes the shutter speed.

In Shutter Priority Mode ( S on Nikon / Tv on Canon ) Exposure Compensation changes the Aperture.

 

In Manual Mode Exposure Compensation won't change a thing since you are in control of everything that it can change ( Aperture, Shutter Speed, ISO ).
Exposure Compensation will work in Manual mode only if you set the ISO to Auto.​

Hi Bill,

 

In Manual Mode, Exposure Comp does not work on Manual/Auto ISO on most canon cameras.. I hear only the 7d2 and the 5Ds/sr only have this feature.  Its a shame since canon cameras are supposed to perform well on high ISO's but have terrible DR, and ISO invariance (like doing an ISO 100 shot, and pushing it to +5 exposure in LR vs shooting in ISO 3200)

One of the things I do often in manual mode auto ISO is to shoot at -.3 EV in low light to keep ISO down a bit when shooting a bird with a dark background. It works well when an osprey is hitting the water to keep from blowing highlights on the splash.

It works on most Nikon's, at least starting from the D3200 and later.

Canon ? Don't know.
Not a big fan.
