Photo Editing On The Cheap by Glenn Euloth

I love photography and as much as I try to get the image right in camera when I press the shutter release there are just some times when you need adjust some overexposed bits or possibly do some custom editing to create a miniature look or selective colouring. Whatever the reason might be there will be times when you need to edit your images. A full out copy of Photoshop is more than $500. Even Photoshop Elements clocks in at $100 or so which is not super expensive but still, if I have an extra $100 I’m putting it towards a new lens or maybe that new tripod that I need.

In my last blog for Photography.ca I wrote about Picasa. Picasa does a wonderful job of basic photo editing, however, it just doesn’t cut it for anything really detailed. When I need more detailed editing capabilities I use Gimp. Gimp is a wonderful piece of software available for free use for Windows and Mac users as well as the original Unix platform. A companion product called ufRAW, also free, allows Gimp to open and edit RAW image files and since I shoot almost exclusively in RAW format it was a necessary add-on.

Gimp will do a lot more than I am capable of doing and I have still used it to do some amazing things. Like Photoshop it allows you to edit images using multiple layers, has many different filters and scripts that can change the look of your images (or parts of it) and also provides many different tools to work on your images. In this blog post I’ll edit an image and provide some screen shots to give you an idea of the capabilities of this wonderful piece of software, however, to really learn how to use it visit the tutorials page on the Gimp site.

In order to give you the broadest tour possible I will take an original image where I’ve done a fair bit of work on the image and walk you through the editing steps that I took to get it the way I wanted. Some of you out there may be much better at photo editing and so you will undoubtedly see areas where I am doing something wrong. Please feel free to comment below so I can learn more about how to do this stuff properly.

Let’s start with this photograph of a butterfly. Here’s the JPEG version created by exporting from Picasa with default settings. All things considered it’s not a horrible shot of the butterfly but the composition is kind of blah and the butterfly’s camouflage makes it difficult to see. Let’s open it in Gimp to see what we can do with this boring image.

First up, since it’s a RAW and I have ufRAW installed it automatically opens in ufRAW for me. Here I can make adjustments to the RAW image before jumping into the Gimp editor proper. For this image I’m going to make a few adjustments here so I end up in Gimp with the basics already completed. This is the general process for me.

From Picasa I right click and select Open in Gimp.
It automatically opens in ufRAW because it’s a RAW image.
I’ve clipped a few highlights 0.1% and so I adjust the black levels a touch to eliminate those.
I then adjust the curves to boost the overall exposure to where I like the image.
Using the crop/rotate/size adjust tab I select a pleasing crop which puts the butterfly on an intersection of thirds and gives him space to “fly into”. Note the grid lines allow me to do this easily.
Clicking OK transfers the image into Gimp for further editing where I adjust the colour levels and pump up the saturation on this one to give that butterfly a little more life.
Next, I’m going to do some selective colouring to really make him stand out. So, I’ll duplicate the layer so I now have two butterflies.
Change the top layer to B&W and create a layer mask that I paint through to expose the butterfly.
I switched to the colour layer and added a touch of unsharp mask to sharpen up the image.
Last, to finish it off, I add a couple of borders, first white, then black and save as a JPEG.

I am a geek and I have been a geek for a long time. ‚So, when I first started managing my digital images I never thought I could trust a piece of software to look after the files on my computer. ‚I would use Windows Explorer to copy the files off of my camera and into a folder on my hard drive. ‚If I wanted to edit an image I would make a copy first and then edit the copy. ‚It worked great but it was very time consuming.

I tried the Kodak software that came with my first point and shoot but it was very slow and clunky and didn‚„t come with a decent image editor so I gave up on it and went back to copying files in Windows.

Google bought Picasa from Idealab in 2004, branded it, and started giving it away as a free download. ‚The Google fan-boy that I am I decided to give it a try and it was instant software love. ‚I don‚„t know how much of it was Idealab and how much of it was Google but I found Picasa to be a wonderful piece of software that did everything I needed in a slick, easy to use package.

First up was image import. ‚I no longer had to launch two explorer windows, create a folder and copy the files from my SD card to the new folder. ‚Instead, inserting the SD card into my laptop automatically launches a window that asks me if I want to import the files into Picasa. ‚All I have to do is click OK. ‚Picasa looks after the copy process and deletes all the images off the SD card after confirming the copy so I‚„m ready to go shooting again.

Next is the easy editing tools. ‚Once the image is in Picasa I can quickly navigate to an image and perform a number of easy edits.

Picasa software — Click to enlarge

Red-eye removal
Saturation and sharpening
Convert to black and white or sepia
Crop to any dimension or aspect ratio
Facial recognition
Straighten the image
Tag and Geotag
And much, much more…

Not only do the edit tools work easily and quickly but Picasa automatically creates a backup copy of the image and performs the edits on the copy so if you make a mistake or if you want a copy of the original you can always find it or revert back.

I ran into a bit of problem organizing my images initially as I was not using Picasa so I had created a 2009 folder and in it I created January, February, March, etc. ‚After I started using Picasa I had a very simple way to upload images to PicasaWeb for sharing with just a click of a button, however, it used the folder name as the album name on PicasaWeb. ‚This became a problem when I started uploading ‚“January‚ images from 2010 as they got put in the same album on PicasaWeb.

To solve this problem I developed the following strategy: ‚At the beginning of the month I create a folder in Picasa with the format YYYY-MM (Monthname), so for example I have 2011-01 (January), 2011-02 (February), etc. ‚This allows me to store and manage the images by date without worrying about duplicates and when I want my holiday photos I can easily search for ‚“December‚.

If you are not sure how to manage your photos or if the software you are using is awkward and not working well for you then I highly recommend you‚download and install it. ‚At the very least you should check out the‚video. ‚Come back next month and I‚„ll talk about advanced image editing without having to spend a lot of money on expensive software.
