我用C730,
想知normal/high曬出來會有大分別嗎????
1027x768可唔可以曬3/4/5R???
如果我曬3R唔係3:2,是不是會丟失了一些邊緣??

想知normal/high曬出來會有大分別嗎???? --> I suppose it is not a great difference between normal and high quality. It's just the compression ratio.

1027x768可唔可以曬3/4/5R??? --> No good. You shall use higher resolution for 3R/4R/5R.


如果我曬3R唔係3:2,是不是會丟失了一些邊緣?? -- > 3R (3.5" x 5"), ie. ration is 7:10. Try this "PhotoCrop.xls" and "PhotoCrop Instruction"

但點解有人講1024x768已可以曬5R,
且無起格, really?

5R: (7" x 5")

Dot per inch dpi (width): 1024dots / 7" dpi = 146 dpi

Dot per inch dpi (height): 731 dots / 5" dpi = 146 dpi (actually not 768 dots because of cropping)

The acceptable dpi shall be at least 150 dpi or the quality will be dropped. Please see GipAlbum for reference.
