This note is aimed to be a quick discussion on High Dynamic Range and possible future enhancements to improve it.

What is High Dynamic Range?

High Dynamic Range is a digital processing effect used within photography to combine a number of images of differing exposures to create a consistently exposed picture throughout the entire frame. This increases the luminance (amount of light) visible within an image.

Why is it required?

The camera’s limitation of amount of colour and luminance it can record is governed by the sensor’s capability and the dynamic range of the camera’s electronics. For example, the Canon EOS 40D uses a 14 bit analogue to digital converter which digitises the analogue signals received from the sensor. The 14 digital bits allow 16,384 different colours to be recorded within the camera.

Looking a a histogram, the horizontal axis is the level of luminance of an image. The vertical axis represents the amount of the image which contains that level of light. For example, a histogram with a single line at the left hand edge shows that the image is purely black. Likewise, a single line at the right hand edge represents an image which is purely white. The amount of data which may be compressed within the histogram is limited by the dynamic range of the camera. A very low dynamic range results in the horizontal axis limits close together. A high dynamic range places these axis far apart.

Introduction

If you have been anywhere near the photography world in the past couple years, I am sure you have heard of HDR by now as there have been countless tutorials floating around on how to create HDR images using 3 bracketed exposures in programs like Photomatix and Photoshop. However what if you don’t have your tripod or if you are shooting a scene with moving subjects, yet you still want to create an HDR type shot? Well, good news, it is possible.

This tutorial will teach you how correct and produce a single RAW image into an HDR-like masterpiece using only Lightroom! That’s right, Photoshop skills are not even needed for this tutorial.

Some time ago I wrote a post on batch resizing images in Photoshop and another on resizing in Lightroom.

One of our readers wrote to me recently explaining that he is using Photoshop Elements and that the resize feature in Photoshop does not work in Photoshop Elements. He is correct, but there is a way of batch resizing in Photoshop Elements and here’s how to do it.

Step 1

In Photoshop Elements, choose File > Process Multiple Files. This opens the Process Multiple Files dialog.

As a photographer you shoot in Raw or Jpeg, or sometimes both. Then you edit. You may start in Lightroom or Adobe Camera Raw, but many photographers will end up in Photoshop doing more detailed editing of your photographs.  In time, you come up with the “perfect” edit. Now it is time to save.

What do you do? Do you save as a PSD, Tiff, Jpeg, Gif, Png or something else?

This article is not meant to address how you save Raw files to formats like DNG (Digital Negatives). It is meant to focus on how you save to share photos on the web and for print.

Here are a few of the most common formats and why you may or may not want to use them:

Ok, so you own a digital camera and you’ve taken more shots then you can count, and you’ve filled up more space on your hard drive than you have free.

You say you’re going to organize your files but you never quite get around to it, and you sure as hell never print out any images to put in an album or a frame.

The problem: your beautiful, thought-provoking work sits on your computer and never sees the light of day. It never gets admired, wins awards, brings joy or breaks hearts. And this really is a problem!

The solution: take advantage of the amazing sites/resources that the latest version of the web has to offer and enter the world of photography 2.0.
