GIMP ile HDR tekniklerini araştırırken http://gimpology.com/submission/view/fake_hdr_look_in_gimp/ de yazan makaleye rastladım ve okudum. Akşam arkadaşım Volkan ile ilgili tekniği okuyup uyguladık ve sonuç oldukça etkileyici idi. Ancak her fotoğraf için bu işle uğraşmak gerçekten can sıkıcı olabilir diye düşündüğümden ilgili tekniğin scriptini yazmaya karar verdim:

Teknik dodge-burn scriptini kullandığı için öncesinde(veya aynı anda) bu script kurulmalı. Kurulumu ise aşağıda linklerini verdiğim scriptleri /usr/share/gimp/2.0/scripts altına atarak yapabilirsiniz. Scripti “Script-Fu->Baris Efe->Enhance My Photo” altından çalıştırabilirsiniz. Öncesinde auto white balance veya auto normalize yapmanızı tavsiye ederim. “Saturation” ve “Darken Only Opacity” ile oynayarak fotografınıza uygun parametreyi ayarlayabilirsiniz.
Kolay gelsin…
