For me, cs4 photoshop is a fun and an amazingly powerful tool. There are numerous ways you can get around with photoshop cs4 and if you are doing photography, this will be your best friend. While I was practicing editing or enhancing the pictures I took, I found that some pictures looked more alive than the original one.
Here are some of the edits I made:
After: In this image I used the Gaussian Blur Effect to give the image more texture and softness.
After: Here I just softened the image a bit and erased the stick near the model's face.
After: In this image, I wanted to particularly focus the model's face alone making everything else blurry.
After: In this image, I wanted to bring out the subject a bit by stripping away the darkness.
After: In this image, I added some lighting effects so that it would look like that the light coming from the lamp illuminated the subjects.
After: In this image, I wanted to brighten up the model's face.
These are just some samples of the images I enhanced. My next goal is to post more images based on my concepts.
