我想曬3r/4r
用幾多x幾多既size去影最好呢??

[Devil4406]

3R = 1280 X 960
4R = 1280 X 1024

頭先果個係最低要求

2,048 x 1,536
會效果好d

點解唔係越大越好呢？等晒相鋪幫你縮落去張相紙度，唔會仲好d咩？

理論上愈大愈好, 不過愈大, 沖晒機個腦會計得愈慢, 站在顧客立場, 慢都唔關佢事.

Some machine only know 300ppi
So it will resize your photo to 300ppi x 6" and 300ppi x 4" (4R for example)

i.e. 1800x1200 pixel

If the algorithm is not good, the machine resize is much poor quality than you use photoshop.
