9 years in the megapixel race - noise or quality

Conclusion

The A3 prints have shown how the image quality has grown by the increase of the resolution. It also become obvious that the higher resolution helped to get the noise more acceptable. The tiny "particles" are much better tolerated than larger patches.

The development has not only affected the resolution, but the color management and the noise filtering were improved a lot. While the G1 had horrible colors, the G3 and G5 produced beautiful images. The noise reduction in newer models has a positive effect on the printed image, and the washed out effect we see on screen is barely visible, even on A3 sized prints.

One thing is sure: if the target is to print 10×15 cm photos, and no larger prints are made, it isn't worth to replace a G5 with a G10 (we only talk about image quality, the features of the G10 can easily outperform the G5) Those who take photography seriously, and want to make large (A4 or A3 sized) prints every once in a while can take advantage of the higher resolution and the sophisticated noise filtering of the newer cameras.

We also have to mention, that the handling of the cameras, the ergonomics and the user interfaces have improved dramatically. It was more pleasing to work with the newer cameras than with the G1 or the G2.
To me, this test has proved that developments of the last couple of years weren't just some nonsense megapixel races, but real improvements. The higher resolution, besides their disadvantages (e.g. larger file sizes, or higher noise to signal ratio) provides several advantages. At least when images are printed at larger than 10×15 cm.

We would like to thank all those G series camera owners who have helped us to make this test by lending their cameras. Great thanks goes to the DigitCam Ltd for lending us a G10 to include in this test.

First look: Panasonic DMC-FZ18 preview

Manufacturers are predictable at most of the times. The replacement of a camera usually comes 10-12 months after it's announcement, while it is very rare that a camera is replaced after only 5 months. While the new Panasonic Lumix DMC-FZ18 is officially not a replacement model of the DMC-FZ8, this latter model has to get an eye catching price tag to survive the in house competition.

Review: Dust removal systems / sensor cleaning

Sensor cleaning is becoming a standard feature on modern digital SLR cameras. While the manufacturers may use different techniques to get rid of the dust from the image sensor, they all promise clean, dust free images. Do they all work equally well? Can we throw our air blower away? We have tested the four different types of sensor cleaning technologies to see which one will most likely to fulfill the expectations.


Review: Fade resistance test

Do you want your grandchildren to sit around you and see your nice, old, color photographs in fifty years from now? If so, you better watch how you get those digital images printed. While some printer manufacturers promise that the photos will last for over 100, in some case 200 years, don't forget to read the footnotes. Those numbers are usually guarantied only when the prints are stored in albums locked away from sun, heat and air. Since we don't have 200 years to test which prints will last for as long as the manufacturer promises we did a not so scientific, but very demonstrative test to find out which printing technology is the winner these days.
