Solutions for upsizing photos with small objects
|This Article Features Photo Zoom|
Does this sound familiar? You get a great shot of a subject, but the subject doesn't fill the frame. You want to make a cropped enlargement of the subject, but you think that upsizing the smaller portion of the frame will result in a soft, noisy and pixelated image.
If an image is so boring that you notice the noise, it's a boring picture. —Robert M. Sammon, Sr
I wasn't bummed out, however, even though some of the folks on the trip were getting full-frame shots with their 800mm lenses. I knew there was a quick fix in Photoshop that could get me similar end results.
For those of you who have found yourself in the same boat, so to speak, here's the fix. You can use the same basic concepts in Photoshop Elements and other digital-imaging programs.
On a side note, I always try to shoot at the lowest possible ISO setting for the cleanest possible shot. In Alaska, I was handholding my camera in relatively low-light conditions. I needed the ISO 800 setting to get a shutter speed of 1⁄500 sec. to freeze the action of the bird in flight and to prevent camera shake at the 400mm setting on my 100-400mm lens.
When it comes to digital noise, there are two kinds: Luminance noise, which is basically grayscale noise, and Color noise, which shows up as blotchy color pattern in your pictures.
In this screen grab, I reduced the noise a bit more than 50%. I've found that if I reduce the noise more, images tend to look a bit soft.
