HV20 exposure manual control at DVinfo.net

Ron German · May 3rd, 2007, 07:45 AM

I`ve read some threads on exposure manual control of HV20 and I didn`t understand if I can lock the exposure in a specific F stop with the shutter speed already set. As, for example, in 48 (with the camera in 24p).
Thanks
Ron

You can, select TV mode and you can set your shutter speed, then use the joystick to set your exposure.

I have a question, if I set the shutter to be 1/25 and then manualy change the expose (with the joystick) will it overwrite the shutter speed?

Denis, Wes' explanation for Ron would also answer your question. You just set the cam in "shutter priority" (TV Mode) to the shutter speed you want and then use the joystick to adjust your exposure.

Here's the trick...once you set your exposure to where you want...leave the settings visible on-screen. This will lock your exposure into place and this way you will have both your shutter and exposure locked. If you toggle the exposure setting visibly off the screen then the cam will reset your exposure to where it thinks it should be.

Just set it and forget it.

Perhaps a little more detail would be helpful: you can set your apeture (f-stop) in Av mode or your shutter speed in Tv mode. That effectively locks that setting - apeture or shutter. But there is no "M" (full manual) mode per se on the HV20. What happens next in Av mode is if you use the joystick to toggle your EXP to manual, you can change the shutter speed (and if you run out of shutter, your ND's) but you'll never really know what your exact shutter speed is (except maybe after the fact by putting the tape in another camera that does display both apeture and shutter) and the camera just says you're adjusting exposure +/- in increments of "1". In Tv mode, it's the apeture that gets adjusted by going into EXP with the joystick (and maybe some gain once the apeture is wide open), again in +/- increments of "1" (which might end up being 1/3 stop increments but I haven't tested that). So... you kinda have full manual control over your exposure with the HV20 but not really b/c you don't know exactly where you are - at least based on the display in the viewfinder/LCD.

Actually, in my experience, you are able to click out of the "joy stick" mode to clear the screen, and still have exposure locked. It will unlock again when you access the exposure setting with the joystick again.

That's correct.

You are absolutely correct...but...if you find yourself in a situation (while filming) where you want to make a subtle change to your exposure you can ...only if you leave the setting visible on-screen...but once you toggle it off and then back on again it does a drastic jump right back to zero which could (depending on how and what you are shooting) ruin a shot.

Edit: I'm not in front of my cam at the moment but I believe this is what happens.

You can see what both your shutter speed and aperture is at any time by pressing the photo button half way. An excellent tip that was posted by Povl.

Could this thread become a sticky? It's a really useful reference.

I tried this but it didnt work - I dont have a SD card in though - I wonder if thats why?

Ian G. Thompson · May 3rd, 2007, 05:25 PM

Ok, I'm back at my HV20 and what I found is that you most certainly can turn the exposure control on and off without affecting your current setting (in other words it stays locked). And you can make subtle changes everytime you bring it back on the screen. What you don't want to do is accidently hit EXP (which is very easy to do with this joystick)..that will cause the problem i mentioned above.

Patrick Bower · May 3rd, 2007, 05:39 PM

You do need to have a SD card in the camcorder, and to enable Still Image Simultaneous Recording.

Sorry, I"ve been looking for the last half hour at how to enable Still Image Simultaneous Recording and I don't get it. How do you do it?

best,

In video record mode, select menu. Scroll down to settings just above the menu. It should be saying Sill I. off. With the joy stick, puch right, it will give you to image size selection. Select what ever one you want, then push menu button.

You should be good to go. It really doesn't give you much as far a letting you know you snapped a pic...but it will be on your card.
