How To Adjust A White Balance of a Camera Raw File

In today's tutorial,  I'm gonna show you a very simple way of how to adjust a white balance of a photo in camera raw file. A white balance is the temperature of the light at what time this image was shot. As for this, I know it was shot in a cloudy day in New York city. That's why it's very cool so what we want to do is to warm it up to the right temperature. Here is a camera raw photo I'm gonna use:

Step 1:

In adobe photoshop CS3, go to File --> Open to open your raw photo.

You should see camera raw dialogue box


Step 2:

On the right side, change the drop down white balance to whatever your image was shot in. In this case, I chose Cloudy. Camera raw does a pretty good job for this but it's not correct yet.


Step 3:

On top, click on White Balance Tool or (Ctrl+Alt)+I and click on the portion of your image where you think has neutral color. For instance, I know the right top wall has a neutral gray color.So by clicking on that, the image will look warmer.


However if you think it's still not enough, you can slide the temperature or tint to your preference. Once satified, click Done. That's it.

By now, you can see how easy it is to deploy Camera Raw to adjust your photo to a better white balance and better photo.

How to create a single image from different exposure using HDR in Photoshop

Suppose you have a couple of exact same photos with just different exposure levels and you want to make a single photo by merging and capturing both the highlight and the shadow of all those photos together using the powerful high dynamic range (HDR) tool in Adobe CS3. Ok, let's get started. Here are the photos I'm going to use:




Step 1:

We're going to merge these photos together. So in Adobe photoshop, go to File --> Automate --> Merge to HDR... and then browse to all your photos and click Ok twice. You should see the Merge to HDR dialogue box pop up.


You now have the ability to take the photograph and either turn them on or off depending on your personal preference. You can also set the white point preview on the right hand side and I'm gonna turn it down a little bit simply because the fact that we're losing a lot of details of the tree behind.

Step 2:

Once satified, click Ok. Photoshop will create a new file based on the High Dynamic Range photograph that we've just created.


Here you can see how unbelievably powerful this HDR tool is as long as you take the correct exposure with your camera. By utilizing HDR, you have maintained most of the details of the window and all the details throughout the entire room.
