[30D] 例景
{:1_254:} {:1_254:} {:1_254:} unsharp mask 太重手喇~ The process of this photo as below.1. Adjust sharpness, saturation brightness @dpp.
2. Convert raw to jpeg in 640x480.
3. Open jpeg @photoshop to adjust horizontal level but found image a little blur.
4. then, add sharpness again @ddp.
5. add frame and signature using magic hand
Question : why photo open by ddp is sharp but open at photoshop turn blur ? 兩個software對jpeg o既演繹有所不同, 同埋兩個software用o既color profile都可能有分別~
如果我影raw就習慣響機set adobe RGB, 因為個色域廣d, 第一個software(nikon capture NX或者dpp)就用番adobe RGB做color profile, 執好左之後就keep一個tiff作為日後output用~
第二個software, 一般係photoshop或者lightroom就用sRGB, 因為lee個copy一般係用黎擺上網, 一般browser只對應sRGB, 然後就響photoshop做resize, 再推sharpness如果有需要的話, 因為resize完通常都會blur左少少, 最後加簽名post上網~ 學到野... thank you 哂 {:1_347:}
but, why it needs to keep tiff not jpeg....sometimes tiff file is larger than raw file. 嘩 ... Sharp 到有0的刺眼既感覺!{:6_178:}{:6_168:} tiff 壓縮比係會低過 jpeg, bit數都諣過jpeg, output黎講quality一定好過jpeg~
我地做印刷, d客一般都係比tiff圖~
