Something I love to play with is using a razor thin depth of focus to really highlight good separation from the background, a detail of something, or to show off a different POV creatively. Go at it and show me how you do it too. Don't worry if you don't have a lens that gets down to f/1.2, just use the largest aperture you have (smallest f/number) and get in really close to something to get good separation from the background. I don't want to see it achieved in post-production or using that fake portrait mode on your iPhone 7, but rather manually achieving this through the lens. I'll trust that you have done it this way and haven't just blurred the background in an image editor.

The rules are as per normal:


· The photographs must be your own work.

· Be creative and have fun.

· You may only submit one photo per contest.

· Please do not comment on photos until after the judging has taken place.

· The contest runs for one week, starting NOW!

· At the end of the week, The Judge (last week's Winner) will choose a 1st, 2nd, and 3rd place photo, providing as much feedback as possible.

· If the Judge is unable to complete the selection within 48 hours of the deadline for close, then a vote will be carried out to select a winner. This will be based on the number of "likes" each image has. In the event of a draw, the second place winner from the previous week will choose the tiebreaker.

· The 1st place Winner will start a new thread with the topic/theme of their choice, and act as the Judge for that contest. (Winner has 48 hours to create new theme, after that it defers to 2nd place).

· Winners please update the Weekly Photo Contest Master thread


Here's a few examples for you.

This first one achieved it even though it was shot at f/11, because of the distance between the subject and the background and how close I was to the subject.



This next one is using f/10, but has a very thin depth of focus due to using a 90mm macro lens with some extension tubes attached, allowing me to get up really close to this small flower.



This last one was taken using f/2.8 and adding 65mm of extension tubes to a 90mm macro lens, giving a razor thin depth of focus to these dragonfly eyes.

Sorry to be difficult, but, here's an excerpt from my guidelines in the very first post.
"I don't want to see it achieved in post-production or using that fake portrait mode on your iPhone 7, but rather manually achieving this through the lens."
Sorry. I obviously didn't read the rules very well.

Many of you saw my macro images throughout the month of May. I picked one of those for this challenge since I've been on the road the past week. I am not entering the competition this week as I will be unavailable during the judging portion, but still wanted to participate anyway. :)
