Digital Print Size Rule-of-Thumb

R0011745 (Medium)(Baffled Driver: I walked past this taxi driver who gave a baffled expression on his face. He would have to pay for the repairs and probably make do with no income until the repair is done. The insurance agent will certainly up the ante for next year's policy)
I have came across a few questions about the largest quality print size of GX200's images. Well, I have done 4R (4 × 6 inch) and 8R (8 × 10 inch) prints. No problem at all for even 8R size. But the question about the largest quality print size baffled me.
After much asking and searching, EUREKA!
For general use, the largest quality R0011007 (Medium)print size for a digital image is calculated as follows: vertical and horizontal pixel counts divided by 200 respectively.
For a critical use of the photo (in a photo contest, exhibition and so on), make the denominator to 250.
Take the GX200's images for example, the largest quality print size for general use is 15 ×20 inches (i.e. 3000 and 4000 divided by 200); for critical use, 12 × 16 inches (i.e. 3000 and 4000 divided by 250).

Featured Comments by Wouter: This year I made four A2 prints (60 x 40 cm) [Editor's note: i.e. 24 x 15.8 inches]. Two from the GX100 and the other two from the GX200 and they were all impressive. And I am glad that the customers were impressed too.

New Low Prices

The window shopping some hours ago has almost provoked my AgIDS illness.  Just in case you’re in Hong Kong or are coming here, and have the money to burn (All in HK$/ body only): GX200 = $3,280 GRD2 = $3,380 LX3 = $3,180 G10 = $3,280 Prices are available form a gear shop on the 1st floor of the Mongkok Computer Centre.   Besides these new low prices, I found that Wing Shing Photo (55-57Sai Yeung Choi St., MK Tel: 2396 6886/ 91-95 Fa Yuen St., MK  Tel: 2396 6885) is offering a Sony A700 + Carl Zeiss Lens package for HK$9,980 (hopefully, a bargain will make it some hundreds cheaper).

Final Verdicts: GF2 in Action

(The rest of the GF2 review posts can be found here ) It is widely believed that the GF2 is a paradoxical downward-upgrade version of the GF1. So, after all the discussions of its bells and whistles, how does it perform in reality? First things first. Which or what kind of cameras should we measure the GF2 against for that matter? We believe that potential buyers of the GF2, maybe except for serial fad chasers and the diehard loyalists, are attracted by its smallness in size with a larger sensor to achieve better image quality, especially at ISO 800 or above. However, given the less satisfactory handling with for example just one dial, the GF2 cannot assume the place of a primary camera. Put together, these assumptions suggest that the GF2 is more suited to be used as a backup camera for social and street shots. Let's grill the GF2 on this basis. In the Hand An obvious merit of the GF2 is size. It feels much less bulky in the hand than the GF1 or the NX100, and just lik...

Dressing Up

(Camera: Ricoh GX200) On the street, a group of Chinese tourists are waiting for probably pick-up. With oblivion to the surrounding, this man changes his vest for an unknown reason to the author taking the opportunity to do a snap shot of the scene of an indecent taste.  The increasingly common sights, or eyesores considered by some, of people squatting in front of shops or in the thoroughfares, together with more billboards written in simplified Chinese, seem to push this international city towards the Chinese characteristics of the Mainland cities. The other day when the author visited the the aquarium and panda's home in the Ocean Park, there were, among the swamps of tourists, conspicuous signs saying, "Keep Quiet" and "Don't Use Flash".  The management of the Park has obviously deployed a much bigger troop of attendants to carry the signs around. On one occasion, one of those attendants was so annoyed that she went up to a tourist and made a big long...
