pretty well.

BTW,

the image is right out of the camera with no post processing.

I will be adding a few more shots untouched in a couple of minutes for your evaluation.

Chris -

Thank you for your experimentation.

Do you have the time and opportunity to try this for us tonight?

Well, it's a very good shot, but there's noise, for sure. But it's also somewhat lower noise than a lot of cameras would do, that's for sure too.

I'm also wondering if a manual WB adjustment would have helped here. These types of sodium vapor lamps can be notoriously tough on WB systems. Do you have samples of how the G1 would deal with it?

Thanks.

It is a nice photo Chris. No noise at all! I’m surprised to see
the amber shift. Did you turn off AWB or set it manually? On my
G1 the color would be much closer to natural.

Give me a few min, I'll go back out to my balcony for those shots requested.

BRB, have patience & you will be able to see the results.

I did some indoor test for ca. I know if I fire the onboard flash directly to a beer bottle, I can create ca. So here is my test with different focal length and aperture

Thanks for taking and posting these, Chris. Unfortunately, I don't think they demonstrate the point I was trying to get at. The idea of the Av mode was that the user would set the aperture, and the shutter speed would be selected automatically so as not to overexpose or underexpose.

So I'm not sure these are usable for this test. Really sorry.

Do you understand what I'm trying to accomplish? Is there any way to work through this to get near-equivalent exposures so that all that remains is that we see the effect of any CA on the shots at varying apertures?

Thanks for giving this some more thought.

Very nice test, Franklin.

Not the worst CA that a user is likely to encounter, but I think it helps to direct the point we've been trying to get at here. If you want to minimize your CA in situations that are likely to produce it, then you'll need to adjust your aperture to a narrower aperture (higher F-number).

It's up to the photographer to be aware of his conditions and how to tell his camera to do what he needs it to do. Thank goodness for the more advanced modes that these advanced cameras offer. :-)

Thanks again, Franklin.

You are welcome, Ulysses.

I agree. It was just an attempt to illustrate how CA changes with apertures . Not surprisingly, in my test condition, CA decreased to neglible amount when aperture is at f5.6 for all focal lengthes. I hope I can run more test in outdoor environment in the future.

Ok, I updated the Gallery to what I believe you needed to see.

Enjoy.

Chris
 
I think this is what were looking for. If time permits, can you do one last one @ F8/15sec of the same scene. Thanks a lots for your help

Chris, thank you very much. These are much better.

I have a question about the G3. Does its Av (aperture priority mode) not work in the way that other cameras do? When you choose the aperture, doesn't the shutter speed get chosen automatically?

I was expecting the images to look much more similar than they do, only with varying shutter speeds, and perhaps a difference in the amount of CA and the intensity of the star-bursts around the lights.

Additionally, you don't have a sample shot at F2.0, do you?

Again, thanks for your work and patience with all of this.

I've enjoyed looking at these night shots- pretty good.

What I find difficult is comparing like for like, and I just wondered if any of you could take a look at http://www.pbase.com/pdqgp/my_sony_717 and try taking some domestic interior shots that are a bit similar. I started a thread asking for such things but no one has responded so far. I will try again.

I do realise that without being able to duplicate the same lighting conditions etc. the comparison will be of only limited use, but it would be better than nothing.

I don't think that I am alone in wanting to be able to take low light interior scenes without flash and being a little concerned whether the G3 is the best thing for them?
