我save相時, 在影像選項中選最佳時, 品質是10; 但是當中可以去到12,
那麼, 我save相應該選10還是12呢?

[Son]

因為save12時, 相片的記憶會比原相的更大, 為什麼呢?

It depend on what mode you select when you take your photo... super fine, fine or normal.... the resolution is the same, but their compression rate is different.

If your photo is using normal mode, most likely it will be 7 to 8 when view by PS, to upgrade to 12, PS will use its formula to calculate the resize format by the existing data of your photo... basically, it won't be better than your original....

我想請問用photoshop整完張相之後 ..
點樣另存檔案呀 ??

10 同 12 都係屬於低壓縮的 JPEG 格式。不過 12 的壓縮比10仲要低。所以 file size 也是最大的。

How about saving it as tif?

tif 仲大。因為 tif 呢種格式係冇壓縮嘅。
