I think your guide a bit off:confused1:

IMO, 540 x 360 for a 4R print is too little and will result in pixellation.

[madmacs]

yeah doesnt look right :confused1: are the numbers for print or display? 360 x 540 for 4" x 6" is only 90dpi.

for prints should use at least 200dpi. usually i would go with 240dpi or 300dpi. so for 4" x 6", at 240dpi it would be 960 x 1440.

think this will be beyyer from the net (http://www.drycreekphoto.com/icc/using_printer_profiles.htm)

harry, from that link fuji frontier uses 300dpi so maybe can revise your list to use 300dpi. :clap2:

[harrynkl]

if you all got a better guideline to the resolution it better to post here, it will benefits everyone even the newbies and oldies.

[madmacs]

using 300 dpi:

4" x 6" 1200 x 1800 pixels
5" x 7" 1500 x 2100 pixels
8" x 10" 2400 x 3000 pixels
8" x 12" 2400 x 3600 pixels
11" x 14" 3300 x 4200 pixels
12" x 18" 3600 x 5400 pixels
16" x 20" 4800 x 6000 pixels
20" x 30" 6000 x 9000 pixels

omg 16 x 20 need 4800 x 6000 p? alamak like that i cannot print that big already

lol...thats at 300dpi lah. :rofl:

at 240dpi you only need 3840 x 4800 = 18mp :p

at 200dpi, 3200 x 4000 = 12mp :clap:

alternatively you can gradually upsample your image 5-10% at a time to reach your target size.

but hor....that only theory. i have actually printed 16 x 20 300dpi using my "12mp" s5 pro before. still nice and sharp. so just give it a try and dun worry too much about the numbers :thumbsup:
