Unfortunately Jason footage quality varies from situation to situation so from my personal experience there is never a one stop filter that fixes everything.

Magic bullet editors is my main tool to clean-up/hide grain, low light problems. I play around from filter to filter & of course I also adjust brightness/contrast manually if necessary.

Hope this helps.

I guess I'll have to play around, once I get footage that needs "cleaning" as it were.

Thanks guys

Totally agree with Martin L. use manual Focus it makes for a lot better footage instead of getting made when the cam cant focus on anything!

...there's a Gain option on the A1?? Where?!

Also, does anybody recommend the HVL-20DW2 light? 'Cause I do a lot of filming in dark places as well and it would be useful to have a light, but my main worry is that the bulb might go quickly... I did see this on Ebay:

What do you think? Cheap I know, but it's LED lights... says it's 40 lumens though, is that poor?

The exposure lever controls gain and iris. When you drop the exposure, first the gain goes down and then the iris starts closing.

6 stops from the right equals 0 gain and each stop to the right increases gain by +3db.

Exposure = gain setting steps from left to right.
How does this work, considering that the lens has variable maximum aperture depending whether it is zoomed in or out? Assuming that this table is sort of fixed (as opposed to relative exposure baseline in Canon camcorders), it must be correct for the wide lens only, when it can achieve f/1.8

When the lens is zoomed it, max aperture is f/2.1, this table does not have this value. It is possible that this table is fixed in [1, 16] range, but is variable in [17, 24] range. Depending on current zoom it would use aperture in [f/1.8, f/2.1] range.

Do I understand this right?
