| 160690 | 2003-07-17 10:45:00 | I am learning to get the best out of a digital camera. A few days ago on Press F1 someone pointed to the Frog Print site as a good source of info about resolution and quality issues - which it is. I was interested to see they say compression doesn't affect printed quality, and recommend using high compression. I'd always understood that professionals using digital cameras always shot TIFFs. Has anyone had any experience with the effect of compression on print quality? | Shortstop (632) | ||
| 160691 | 2003-07-17 11:41:00 | Thats a very good question Shortstop. I'd looked at FrogPrints, but didn't recall that advice. But you are correct. Just looked again, and they say: "We recommend that you use the highest size setting and the lowest quality setting. This may sound strange, but compression (quality) has very little effect on the print quality of the image." Further more they say: "The critical factor is how many pixels were captured originally." Like you, I had assumed the least compression, and highest quality was better for print quality. I'd be glad to have any comments from PF1ers with knowledge of this quality V compression printing. |

Each time a compressed file is newly saved, there will be a bit more loss of quality, so a professional will accept the cost of big files. Their final "printing" might be on a very high quality photosetter for advertising in a quality magazine. For home use, where you will be printing at 300 dpi or so, or, more likely, viewing at 75 dpi on the screen, you can afford a loss of quality. :D Even with the very high quality professional gear being used, I can still spot a "digital" photograph in a newspaper. ;-) |
