Contrast is usually at its highest when a scene is backlit. In this image there wasn’t much that could be done to lighten the shadows. I exposed so that the highlights weren’t too badly burnt out and didn’t worry too much about the shadows. Contrast […]
Rsizr – Image scaling on steroids
While Photoshop, Lightroom and Photoshop Elements can resize images for you, only Photoshop CS4 supports content aware scaling. I’ll talk about this new feature in Photoshop in another post but if you’re interested in playing with content aware scaling and you don’t own Photoshop CS4, check out Rsizr.com
Rsizr resizes images by removing the unnecessary content from them or by stretching neutral areas of the image to make the picture bigger. It’s worth a visit just to see it at work.
Start by uploading an image that you want to resize. This should be a JPEG, .PNG or GIF file with a height and width of less than 2,880 pixels – in practice, so you can see what’s going on quickly, upload an image sized smaller than this.
Once the image appears in the dialog you will see tabs with buttons for various functions including the File Function tab, View functions, Resize and Retarget functions.
The program uses a seam carving technique to remove portions of the image. To get started drag the horizontal slider in the top of the window in to the size you want the image to be resized to. Click the Retarget button and watch as the seams are created (they’re the red marks you can see in the image) and the file shrinks in size.
Once the seams have been created, you will see a set of sizing handles around the image which you can use to resize the image either to make it wider or narrower.
You can protect areas of the image or mark them for deletion by clicking the Preserve or Remove indicators on the retarget functions tab and paint over the area to keep or remove.
You might do this, for example, if you see some distortion in the resizing process and want to protect key portions of the image.
The rescale and crop tools are similar to what you’re used to using in your photo editing software – it’s the retarget option which is unique.

Next time you’re in the countryside at night do yourself a favour: look up. If it’s clear and conditions are right you’ll see a seemingly infinite number of stars twinkling like diamonds on a sheet of black velvet. As a visual pleasure it’s hard to […]
Colour can be distracting. Stripped of colour an image is entirely about the subject (unless of course the entire point of the subject is its colour…). This is particularly true of portraiture. Black and white arguably conveys the inner soul of the subject more powerfully […]
