That’s still a bit difficult… Many phones have pretty bad cameras on board, just adequate for sending simple, small images to others. We digicam lovers like more pixels, less color fringing, exposure control… and that’s offered by the better phones for some time!

The pictures above show the city of Gouda in Holland at daytime (very easy to take; just select the correct white balance) and when evening is falling. The latter situation is still very difficult for the latest phones - and much more of a challenge!

However… things are still getting better and it’s encouraging to see manufacturers working hard on improvement.
Some time ago, I wrote about the Nokia N93; now a pretty good review about the Sony Ericsson K800i has appeared on digicamreview.
Bottom line is that this model is some improvement on the W800i (used for taking the pictures above) - still not ideal, but getting better!

So: never forget to take your phonecam with you, but for now you better accompany it with a “real” digicam if you like better and bigger pictures!
