Manual vs green box

Last night I was trying to shoot my living room. I was playing with the pop up flash on my 60D. I was in manual and could not get the exposure right, way under exposed. I flipped it to the green box to see what it would do. Well perfect exposure, or almost. So I took the settings it used and applied them to manual mode. Manual still came out way under exposed. The settings were, iso 400, shutter 1/60, aperture 3.5. What am I missing? Seems like they would be the same exposure.

Thanks in advance

Were you shooting exactly the same thing with those settings or did you take pictures of something else in your house?

post the pics with exif intact

Assuming you pointed at exactly the same area, did you play with flash exposure compensation settings at some point in the past ? Auto sets everything, but MF or any of the creative modes revert back to the old setting you may have inadvertently set months ago.

EXIF would help.

The green box will use evaluative metering, and you might have the camera set to centre weighted metering for all other modes.

I was thinking you guys were going to ask for exif. I have been playing with camera so much, I haven't hooked it up to the computer yet. I will do that today. Focus and everything was the same. I went into the menu and checked to make sure there was no fec.

Thanks again

manual mode means you are going to manually tell the camera what the right exposure is. In manual the camera does not set exposure, you do.

How would this affect exposure in M?

Menu>Flash control>Built-in flash funct.setting>

>Flash mode:ETTL
>Wireless function: Disable

If the wireless function is on, even though you do not have a slave, may mess things up.

If you choose Manual instead of ETTL, you better read the Manual and know what you are doing.

The reason I asked if you took the exact same picture of the same thing is because light falls off rapidly, and just because you can shoot with those settings at one side of the room does not mean that the same settings will get you the correct exposure on the other side of the room. Does that make sense?

It's also why I didn't ask for your EXIF data, the shots, etc. - I'm assuming you told me the truth - that it was the same exact settings for the ISO, shutter speed and aperture. It could be you weren't right and the aperture changed, too? But I believe the easiest explanation is you took a shot of something farther from the light source so it wasn't lit as well.

Okay, so if wireless is enabled, it is still trying to send a signal somewhere? I had it set to wireless.
That might be it.
Thanks for the tip. I will try tonight with the same lighting.

With wireless on and Manual rather than ETTL it does not allow the popup flash to go above 1/4 power. It assumes that you are just using the popup for fill/catchlight and the main is Off Camera (wireless).

Oi - I should knock off the drugs or something... completely missed the flash part. Go ahead and mock me now. (in my defense I am having a really bad morning)

I did have it set to wireless enable, and ettl. I will still try to disable wireless.

Thanks again.

Thanks all. It was because wireless was enabled.
