Also an opportunity to discuss a little known post-production technique for photographers.
I was using a wide angle lens and too much background was in focus. What do I do? Many may not be aware but Photoshop has a select by focus function.
You can let it choose the focus area and then use Gaussian blur to defocus a zone. Only disadvantage is that a huge image such as the 36 MP image from the A7R can be back breaking for the PC.
Sometimes the auto selection if off target and you may need to trim the depth manually.
