Being honest with you, these are news to me. To be more precise I new light helps avoiding noise but I never thought of overexposing and then post balance!

So really thank you.

By using ML am getting any kind of advantage at DR or better noise controll anyway at images?

I think it is clear!
Excellent! Thank you!

I think you are both wrong!

Lolololololo

You are both good very good!
You have a very intresting approach whichs sounds very logical.
So you suggest to slightly overexpose images at 100 ISO and then just balance in post and in the end I will have better results, correct?

That won't get you much less noise but it will allow you to use slower shutter speeds since you aren't changing the overall exposure and you're reducing the DR anyway.
So, it's not a win-win- situation but more something you know how to use at your advantage.

By decreasing the gain, i reduce the dr?

At such low ISO in video or photo mode noise is a non-issue.

Yes you are correct, but to be honest with you i was hoping for ML to give a boost to even cleaner images even at this low iso's. At dark areas even at 100 iso there is some noise. I Admit, not important but there is noise. At 200 300 level it is quite annoying already, and i hoped for better results with ML.
But ilguercio is havinh an intresting approach on the other thread, if you would like to join.

Thanks

How are you going to increase noise if an overexposed image actually gets more light than the correct exposure?
ISO isn't the only way to measure noise. If you take a shot at 100 iso underexposed by 5 stops it's going to be a lot noisier than a shot taken at 400 iso at the correct one.
Boosting more light into your shot, even if the exposure is not correct and as long as you don't clip the highlights, is the best way to get the maximum amount of light for your scene so you can get more light into the picture, improving the signal acquired by the sensor and taking the exposure back to normal in post production.
Does it make more sense now?

Agreed, but post proccess  always produces noise.
So what ever you ""earned"" at an overexposed capturing, you give it back at post proccess.
Am i mistaken??

Thanks for rapid reply!

So is there a way to reduce noise further?
If I use iso 200 and a gain of -0.3 ( iso 160) am i going to get images with less noise?

No.
Or yes, just overexpose a 100 iso shot by 1 or 2 stops and then restore it to the proper exposure in post.
There you go.

Sorry, but is this correct?
This way you will increase noise. ISO 50 is supposed to decrease noise even further. Am I missing somthing?

Hi to everybody and ML is an amazing software. If I was canon, I would have a good contract with you!
I use a 50d and there is no way I can set the ISO below 100. If I set 100 ISO then the gain is not allowing me to set negative EV values, is something  I am doing wrong?


My main concern is to reduce the noise of 50d even lower than iso 100 does.
