Graduated Blowups

In amateur photography, a lot of fun can be had in simply blowing up photos in  graduating sizes. It can be an educational process, as well. Sometimes when focus on a subject seems certain, one can learn from a blowup that he wasn’t quite as focused in for his shot as he thought. Blowups can teach one something, after all.

The first picture in this post of a Canada Goose was isolated from the original picture of two birds (BELOW) and blown up to feature him alone.

And (BELOW) are two other blowups in graduated sizes also made from the original picture.

In digital photography, one may easily recognize that focus must be absolute to ensure a focused blowup. As demonstrated in these particular blowups, although the first picture of the two birds together looks quite focused, there is considerable pixel loss in the graduating blowups, causing a loss of focus that at first seemed certain.

A correctly focused example follows (BELOW):

The original photo was taken right through the railing of the bridge, while the camera was focused correctly on the geese. The railing faded out and the geese stayed in focus as the camera followed them. Therefore, the two graduated blowups are perfectly in focus on the geese, as well.
