How to edit a low light image with Photoshop CS4

The beginning of this video shows exactly why you should shoot in RAW.

What a difference the white balance makes when changing from Tungsten to  Fluorescent. When I first started using my DSLR I  always had the camera set to Auto WB. I figured the camera could worry about that since I wasn’t exactly sure what it was all about.  Then I started shooting in RAW and seeing for myself during the editing process what a difference your WB choice can make on your image. If you want to get the correct colors in your image you need to make sure your WB is set accordingly.  That is the beauty of shooting a RAW image, you can edit it after the fact!

Be sure to check out some of Photo Gavin’s other photography videos… But first there are some good tips on editing your low light photos in this video. He is using Adobe Camera RAW for processing the image. The basic settings in Lightroom and Adobe Camera RAW are similar, so even if you’re using Lightroom to process your images you should take a moment to watch this video.

All the tips within can be applied to your other photographs as well, it doesn’t have to be a low light photo.


How to Dodge and Burn in Photoshop cs4

Recently I learned a new technique on how to dodge and burn in photoshop cs4! It works great for dodging and burning on a different layer so it doesn’t impact your main picture. This way you can turn the layer on and off to see exactly what has changed in your picture.

I recently went to a scrimmage game at the University.  The clouds were amazing that night swirling around in different formations. One minute you thought it was going to rain the next the sun was shinning through.

First you will want to open a new layer

  • Layer -> New -> Layer
  • When the box comes up name your layer (good habit to always name your layers)
  • Mode – Overlay
  • Once you change the mode you will you want to check the box directly underneath that says “Fill with Overlay-neutral color (50% gray)
  • Click o.k.

Now you should have a new layer above your picture that is completely gray. This is the layer we are working on so make sure it is selected by just clicking that layer in your layer panel. If your layer panel isn’t open go to window -> layers or press F7.

Next we need to select a tool

Dodge – will  lighten

Burn – will darken

Right click on your tool bar to see the options

Once you choose your tool you will have a few options on the top of the screen

Brush size (You can also use your brackets on the keyboard to increase or decrease the size of your brush while you’re working on it.  Choose how hard or soft you want your edges to be. I went with a softer one so it would blend nicely into the picture.

Range  – I usually start with the midtones at an exposure of 20%.

Play for awhile and then turn on and off your dodge and burn layer to see the difference! this works great on clouds or lighten up faces, playings with shadows etc.

This picture was taken with the Canon 60D using the Canon 18-55mm lens at a focal length of 18mm.  Set to Manual / shutter speed 400sec at f/8


How to extract an image Photoshop CS4

This is a quick and easy way to extract an image from Photoshop CS4– First your going to open your image right click on your background layer and select duplicate layer. Now you should have two layers exactly the same.

On one of the layers use your selection tool to select what area you want to extract. Don’t worry if it selects a little beyond what you are working on we can clean that up in a minute.

With you mask tool open (Windows->Masks) click on Add A Pixel Mask

Turn off your first layer so you only see the layer you are working with.  Use your eraser tool to erase anything that is obviously not part of the image you want extracted. Now look for the feather tool on your Mask editor and feather the edges a little bit.

Now you can work on either the background layer or the extracted layer.
