ni aku usha2 tentang PWLImage Enhancement – Paint with Light
This is a method of adjusting the brightness or darkening parts of an image without affecting the overall total brightness/ or darkness of an image
If you look at the example, the original is at the top and the texture of the guy’s clothing is indistinct, I do not want to brighten the background or the faces.
Using PWL you can very selectively make changes to any image to give the feel that you require, it also works with B&W images.
There is no reason why this method should not be adaptable to Corel Paint (Paint Shop Pro) and it certainly will work with GIMP or GIMPSHOP.
I use Adobe CS2 and here is my method.
Open image
Ctrl+J to duplicate the background layer, this way you are using non destructable methods.
Ctrl+Shift+N This brings up New Layer box
Enter the following
Name - PWL
Color – Grey
Mode – Soft light
Do not tick – use previous layer to create Clipping Mask or Fill with soft-light-neutral color (50%)
Click OK
You will now see in the layers palette a new blank layer
Press D to reset foreground and background colors to Black and white
Select a Paintbrush, I usually use a soft brush
Set the following
Size as required usually up to 200
Mode – Normal
Opacity – 2 to 15%, Its best to start with about 5%
Flow – 100%
Now if you start with the foreground color as Black and make sure you have the New Layer PWL selected and paint on the light areas of the image, at portion of the image will darken,
To select theWhite as the foreground color, Press X
Now when you paint on a dark portion of the image you will see it lighten.
You can experiment with opacity settings and brush sizes.
When you are finished, you can now make a New Visible layer by Holding the ALT key down, and going to the little arrow above Opacity in the layers palette, then croll down to Merge Visible, click this item, then release the ALT Key on the Keyboard.
Give this a try, it works for me
siap ngan tutorial lg.. :lol:

klu ada gambar snap print screen kan lagi best.....hehehehehe, anyway good info...Link plezzzzzz.............. kalau guna satu pic kemudian kita adjust brightness pic tu dalam pc dan save as kepada 3 bahagian dengan brightness yang berbeza dikira hdr ker tu? klu 1 image raw file boleh la kira......itu org kata 1 photo punya HDR, tp klu jpg file......silap2 memang x jadik...

Ko guna JPG ke RAW file? Ada software klu ko ubah JPG exp dia boleh guna kat Photomatix pro tutuk buat HDR tanpa kuar erro, setakat aku guna la :):).Pastu software apa yg ko guna?
Klu pandai godek2 photoshop pun ko boleh buat pseudo HDR dgn satu jpg photo.
Pseudo HDR aku...

hammohd......Nak bagi tutorial entah la......tak ada yg terecorded step by step..... tapi mungkin orang lain ada kot, lagi pun dah lama dah tinggalkan editing nih...
Tapi klu ko ada amik gambar yg sama dengan 3 exp yg berlainana normal, under dan over dah cukup tuk buat HDR guna software photomatix. Software nih akan calculate dan generate sendiri HDR dan ko cuma main2 dengan tone maping jek lepas tu.
over expose tu tuk naikkan shadowed area punya details dan under expose tu tuk naikkan highlight punya details.....pastu bila gabung dalam Photomatix nih dia akan keluarkan semua details untuk jadikan High Dynamic Range photo........ Betul ke nih?
