Probably should have hit the macro setting for both of these shots.  The second uses the flash.

ISO 1600 f:4.0  1/13s (hence the blur)

ISO 1600 f: 8.0  1/60s

    Despite a little motion blur, I like the first one with the blurred background! A good study of depth of field.

    F/8 and be there! too safe, F/4 is cooler!

    Hmm…if anything, I would expect ISO 1600 f4 to provide a clearer shot w/o flash than ISO 1600 f8. That 1/13s I think is what did you in on that shot.

    Often times with lesser point and shoots, what is dubbed as “anti-shake” is actually the act of raising the ISO, making the sensor more reactive to light, resulting in the use of a higher shutter speed to take a faster image to avoid image blur.

    It also tends to result in more noise.

    Is this the G10 you’re using?

    Yeah, this is the G10. I think if there had been enough light for the first shot, I could have gotten the shutter speed up a little. What do you mean by “noise”?

    “Noise” is/can be the result of electronic interference and high sensitivity that appears in the shot. It often shows up in darker areas and is more frequent the higher you boost your ISO as the sensor is becoming more sensitive to light, it’s also becoming more sensitive to electronic interference.

    You want to try and keep your ISO as low as possible to take the shot. What “as low as possible to take the shot” means is ultimately up to you and the desired effect you want. I know that’s a short answer but while it leaves room for a more technical exploration of the topic, it’s still overall true.

    Here’s a good basic primer on what noise is. That’ll get you started and from there, try and find some other sites that discuss noise, sources of noise, and ways to reduce noise.

    Some good sites to check out for questions of all stripes are http://kenrockwell.com and http://www.luminouslens.com/.

    And you can always ask me questions anytime you want. And you know Albert Yee, right? I often hit him up with questions when I need a good seasoned opinion. I’m sure he wouldn’t mind if you bounced questions off of him from time to time. That’s how I got a lot of my questions answered. But anytime you do have a question, please feel free to fire them my way. I’ll answer what I can, find sources for what I think are good things to read, and defer to others who I think can better help if I can’t.
