First i export the file from PM to Capture NX. When I´m done with the adjustments I save the file as NEF. Then in PM I save the file From NEF to jpeg,apply IPTC, Preserv Exif, Watermark, Save it in folder at desktop, no scaling, convert to sRGB, Use embedded preview.
From my blogspot page i make new blog and import the file from desktop. The file is ok except when I enlarge it in blogspot it turns bW.
If I save the file as jepeg in Capture NX or another application it works fine.
