Optimizing Photos for the Web

Optimizing Photos for the Web

  1. Edit image.
  2. Resize image.
  3. Sharpen small (≤ 500 px in width) images with the Unsharp Mask and larger images with the High Pass Filter.
  4. Reduce noise.
  5. Make the file size smaller by using Photoshop’s “save for web & devices” option. The difference between jpeg high (60), jpeg very high (80) or jpeg maximum (100) is barely noticeable. I usually save small/medium images as jpeg high and large images as jpeg very high. Make sure the convert to sRGB box is checked.

How to Sharpen Photos: An Introduction (Easy)
Read More: http://digital-photography-school.com/an-introduction-to-sharpening-photos

Summary:
1. Sharpening should be done at the end of the editing process.
2. Create a flattened version of the image either by flattening or merging all the layers. The Unsharp Mask works only on the current layer.
3. Use the Unsharp Mask (Filter > Sharpen > Unsharp Mask).
4. Note: There are other sharpening tools available which do an even better job of sharpening than the Unsharp Mask. Use the Unsharp Mask method primarily for small images (i.e. 500 px).

Resizing (Resampling) Images

Resizing vs Resampling

Usually, when people use the word resizing, they actually mean resampling. Technically, resizing means changing the ppi (pixels per inch), or the resolution, of your images. Resolution and ppi become significant when you wish to print photos. For example, let’s say you have a 12 megapixel camera. This means the photos you take will have 12 million pixels (4,000 pixels by 3,000 pixels). If you want high quality prints, your photos should have a resolution of 240-300 ppi. At a resolution of 240 ppi, your photos will print at a size of 16.6 inches (4,000/240) by 12.5 inches (3,000/240). At a resolution of 300 ppi, your photos will print at a size of 13.3 inches (4,000/300) by 10 inches (3,000/300). Notice how the print size of photos decreases as the ppi increases. Changing the ppi of images will change the sizes the images will print, which is why it’s referred to as “resizing.”

The image on top is a screen cap of how the Instructions.png appears in a WordPress post when its width is 570 pixels. The image on the bottom is a screen cap of how the Instructions.png appears in a WordPress post when its width is 565 pixels.

You may have noticed that your images sometimes appear blurrier when posted in your WordPress blog. It’s not very noticeable for photographic images, but it becomes very noticeable for line or text images.

I was confused as to why this was happening because, having read that WordPress was a poor image resizer, I made sure to resize my images before uploading them. According to WordPress, the maximum content width for my theme,Twenty Eleven, is 585 pixels. However, even though my images were resized to 580 pixels in width, they still appeared blurry in my WordPress posts. Interestingly, though, when I visited the direct links of the uploaded images, they appeared crystal clear.
