Here is my layout using Manu's great qp from the April Mega kit:
I am a fan of photo actions, but for these photos, I found a quick way to 'pop' them. I started by simply increasing the saturation of the photos, then I increased the brightness and contrast. The final step was to use the unsharp filter and really increase the percentage. I used 200% on each of these photos. A definite number can't be listed, it is more, 'salt to taste' type technique.
