Being the only designer geek in a family full of programmers I get called on for anything IT that involves images or Photoshop. Recently I have been asked several times how to sharpen a photo well and so that the end result isn’t blocky nor hazy.
To demonstrate I’ll show you an original image (Photography in Margaret River Lake Cave in Australia – no light and no tripod!) After the original image I will talk you through three simple steps to a nice sharp image.
Open you image in Photoshop and go to image – mode – lab colour. This doesn’t look like it’s done anything but go with me on this!
Go to the window option and select layers. On the layers panel select the lightness channel to only edit that one channel.
Go to the filter menu and select Sharpen – Unsharp Mask (this gives you more control than just Sharpen – Sharpen) Finally, adjust the sliders until you get the image just how you want it. Convert you rimage back to RGB in the image – mode options and there you have it, a nicely sharpened image.
