Not certain if this belongs in the video part of the forum but it relates to the Panasonic G7 camera.

I'm trying to teach myself to record manually when recording video.

I've set the shutter speed to twice the frame rate and set the aperture to around f16

I won't use f/16 unless I need that DoF (eq to f/32 on FF) since diffraction will soften the output.

While it is too bright, use a ND filter instead.

as the shutter speeds is a low 1/50 sec (frame rate 25 fps). I can't see anyway of making the iso auto so it compensates for changes in exposure so I was wondering if there is anyway of altering the aperture or iso setting while I am recording; if I pan the camera to a shaded area I need more exposure.

I usually shoot with S in M-video mode. Set the SS at 180 degree rule, Auto ISO. Use Exposure Compensation for the brightness condition of the footage. TBH I had used faster shutter speed (e.g. 1/120" for 30 fps) and the output remains smooth.

If it is too bright, a ND filter is the best.

I'm looking for an easy way of quickly adjusting the exposure such as putting my finger on one of the camera dials to make adjustments while continuously recording.

On GX85 and G85, I set the front dial to control Exposure Compensation for quick operation.

Hi alcelc.

It's more a case of being too dark.

If you are not in M mode, G7 should be able to adjust the exposure for us, might not be as we wanted, but at least to 0ev metering.

For example if I pan to a dark area of a scene that's in shadows I'd need a way of opening up the aperture more to let more light to the sensor.

Doing exposure compensation (EC) is likely to rectify the condition when the brightness on certain section not to our satisfaction.

It's either adjusting the sensor or adjusting the ISO.

We can't adjust the sensor. 😋

The same as still shooting, in A or S mode under M-video, we set either the f/stop or shutter speed, G7 adjusts on the remaining parameter and ISO to keep 0ev meter exposure.

Maybe there is a way of temp assigning the Iso or aperture to one of the cameras control wheels so that I can make adjustments while recording.

I am not on my computer hence cannot access to the G7 manual. But I trust UP cursor key can set ISO.

I noticed in your text that you used Auto ISO, I have not found a way to do this in the camera video recording mode. If you know how it's done then please let me know.

As per G7's manual that I read, Auto ISO is available to M-video.

Thanks aleclc.

Thanks for the info.
I made a mistake in my text I meant adjust the aperture and not adjust the sensor.
Good to know that what I need is in the manual as having an Auto ISO should solve the problem as long as the ISO does not get to high as noise can be more noticeable than in a still photo.
Must take another look at the manual.
