Hmm I managed to create bokeh, I held out my hand in front of the lens, made it focus on my hand and the background wall about 15 feet away was blurry.. LOL.. obviously no match for your sigma 1.4.

I just picked up a 10 stop ND filter.... will be interesting how shots turn out with it!

That should pretty much settle why a dslr beats a point and shoot when I can keep it away from the pouring rain!

WTF is a 10 stop ND filter?

Filter that makes shots like these possible:

Basically what it does is it blocks 10 stops of light so you get a long exposure in shutter priority or bulb setting. Even an ordinary lens turns into an OMG lens with this filter.

Sure thing.

Basically it works like this, it blocks 10 stops of light so say a normal exposure of a landscape overlooking the gulf of thailand for you is f/8, 1/500th, ISO 200.

So 1 stop reduction to compensate: 1/250
2 stop: 1/125
3 stop: 1/60
4 stop: 1/30
5 stop: 1/15
6 stop: 1/8
7 stop: 1/4
8 stop: 1/2
9 stop: 1 sec
10 stops: 2 seconds (correctly exposed with the filter)
11 stops: 4 seconds, compensate with bringing aperture down to f/11
12 stops: 8 seconds, compensate with bringing aperture down to f/16
13 stops: 15 seconds, compensate with bringing aperture down to f/22.
14 stops: 30 seconds, compensate with bringing ISO down to 100 making final exposure, f/22, 30 seconds, ISO 100

There you have a long exposure that might blur everything and give you the dreamy effect. It's a crazy calculation but it works.

Once you learn it, photography becomes manipulation of light via mathematics! :twisted:

Oops even I messed up in my math but fixed it.

And 10 stop is somewhat of a drastic filter.. but it can create wonders like this 76 second exposure.. someone must have used a stop watch and the bulb setting..

1 thing I dislike about all point and shoots is, when you buy em, price drops like a rock and in 2-3 years its worth 10% of what it was unlike DSLRs. But still need is need. I don't blame you at all if you don't get a point and shoot.

Found 2 more perks in my P300:

1. If a lens has VR, Use the damn VR!!!! I was getting some out of focus shots and then realized by depressing the shutter half way first, letting the VR and focus engage creates non blurry shots.

2. you mentioned the sensor is smaller.. but when I used photo resize with your settings and downsized the image from 4000 x 3000 to 800 x 600 excellent quality (90).. I swear there was not 1 pixel of noise in the image.. it was super ultra sharp. To the naked eye, they could never tell it didn't come from a dslr.

You will see image quality differences due to sensor size in low light on high ISO settings.

No matter what the pixel size, larger sensors unavoidably have more light-gathering area. Theoretically, a larger sensor with smaller pixels will still have lower apparent noise (for a given print size) than a smaller sensor with larger pixels (and a resulting much lower total pixel count). This is because noise in the higher resolution camera gets enlarged less, even if it may look noisier at 100% on your computer screen. Alternatively, one could conceivably average adjacent pixels in the higher pixel count sensor (thereby reducing random noise) while still achieving the resolution of the lower pixel count sensor. This is why images downsized for the web and small prints look so noise-free.
