Tech Tuesday…Depth Of Field Part 4

We’ve pretty much covered most of the factors that affect depth of field…Aperture, Focal Length and Distance. What do we do when the laws of physics simply don’t add up to the numbers we are trying to make an image? We have chosen the appropriate lens, composed the frame, closed out lens all the way down and we just can’t get enough depth of field. Not only that, there is a slight breeze so, that small aperture is giving us a slow shutter speed and we are getting subject movement. Do we pack up our equipment and chalk one up to the photo gods as winning? Or, do we look in our bag of tricks and pull out Helicon Focus software? I for one vote for the software. I must have wanted the image in the first place as I set it all up. I just couldn’t get the shot I wanted with the equipment I was using. So, with my tripod set up and the frame composed to my liking, I set the focus to manual and focused on the very front petal of the flower and I opened my aperture up (you heard right…I opened my aperture up) to 2.8 and set about shooting 24 frames focusing a little deeper into the flower with each click of the shutter. This gave me 24 images with various parts of the flower in focus. Here are three to give you an idea…


Middle Focus


Far Focus

Now, I’m not a glutton for punishment. I have no intention of painstakingly masking in the sharp areas one frame at a time. No, I’m going to let Helicon Focus do the heavy lifting for me. I simply launch the software, tell it to merge the 24 frames and I go make a cup of coffee while Helicon puts it all together…

All I had to do is add my own creative touch to finish the image off. I ran NIK Tonal Contrast, Glamour Glow with the glow reduced and Darken Lighten Center and I have the image that I saw in my minds eye when I clicked the shutter.
