[Beginner's Question] How do you know if he used photoshop or not?

[jinjin]

Hi everyone, I am learning how to use the photoshop recently.

and now I have a Beginner's Question....

how do I know if a photo is processed with photoshop or not?

for example, I saw this photo
Photobuyer: Spring in Tokyo

the lighting in this photo seems little bit weird.
I am suspecting that he used photoshop.
but, how do I know the truth without asking that person.

is there a way to know?

Used photoshop in what way weired ?

[Dreamglade]

Simple answer you don't. If they are good and not over-the-top then you won't notice and that's the point. Most photographers will do some post-processing after the shot, sharpening, levels, whitebalance, exposure, lens-distortion correction etc.

But to me, the image looks ok, just with a lot of blown highlights. Maybe purposefully bumped up the exposure in post? Who knows. If you're so interested, you should ask

The light doesn't look weird. The picture is overexposed.

hey, thank you for everyone's reply,

at this moment I am trying to learn photoshop on my own.

is there any web site that you guys think its good for beginners to self learn photoshop?

youtube if you want to do it free and have time to weed through the crap.

Lynda.com if you dont mind paying 20 bucks for better education than you deserve for the price.

[Doug Sundseth]

Either Lynda or Kelby Training. The fast way is to pay. If you have more time than money, Kelby has weekly shows that will give you tips for free, but they're scattershot rather than a focused learning path.
