Do you have any tips on how to shoot with the EX1/3 in low lighting environment ?

Try Alister Chapman's "Low Light" picture profile and you generally should stay on a wide zoom with the iris fully open to allow more light to enter the lens. Remember to use manual focus and generally use a tripod.

Here's a great tip: Add some light!

I'm currently working on a new music video for my wife and I'm shooting it in "candle light". I gently flooded the set with additional light. With a bit of color correction, it retains the look of being lit only with the candles. I did not use any boost on the camera and I have don't have much noise in the images.

Oh Kevin.....there you go getting all "professional" on us! After all, who needs to know anything about lighting when the cameras will do all the work?

;-)

In case anyone might be interested, here's the candle light video:

Getting the color effect on the skin tones took a bit of tweaking. (the auto-correct on my phone was sure I meant twerking, that would have generated some questions)

Kevin, I think the video is very well done and I really like your wife's music. My only critical comment is that I think it is underexposed even for a video that is probably meant to look a little underexposed.

Thanks Doug! Yes, it is underexposed, I had it brighter and didn't like it. Since this will only be on youtube, I decided to leave it dark - actually youtube put up a dialog window saying it was in need of improving and I could click their little button and they would fix it. I never seen that notice before.

Nicely done, Kevin. I really enjoyed that!
