I am going through backup Hard Drives clearing out files not needed to clear up some of my storage space. I found this image of an Male Eastern Forktail Damselfly covered with the raindrops after a heavy rain. I thought it looked interesting with the heavy amount of raindrops. I was using a Sigma 150mm macro lens with a 1.4X Teleconverter on a Canon 1D MkIV. To get more in focus but still keep a soft uncluttered background I was shooting with my aperture @ f/4.5. I shot 9 images along the Damselfly and the water drops . Then loaded them into 1 layered Photoshop file to blend into my final image. Luckily the Damselfly did not move as I was photographing it. The 2nd image is a Immature Female Eastern Forktail Damselfly shot at the same session as the Featured Image.
Quite often I use Image Stacking techniques for my macro images. This works best if you are using a longer macro lens for shallower depth of field & softer cleaner backgrounds. I shot with the lens wide open and take images starting from the closest area I want in focus & ending where I want the background to go softer. The image I chose for this blog is one I photographed years ago. It was photographed using a tripod with a Sigma 150mm Macro lens & 1.4x Canon Teleconverter. I also went a little overboard on layers, but because I was using a 150mm lens with a 1.4x Teleconverter I shot more focus points than usual. I ended up with 44 images in this stack. But shooting @ f/2.8 & adding the 1.4x teleconverter it was actually f/4 (Wide Open). I started from the bottom of the image & worked my way up to the top. You can also not use all the layers if you want to select where the softness ends or begins. Here I purposely ended where I wanted it to end. You can also use a smaller aperture / larger f/stop number to use less images for the stack but I like the smoother background.
I then load all the images into one Photoshop layered file and select all layers.
A) Under Edit – chose Auto Align Layers
(B) then select Edit – Auto-Blend Layers – for final blending.
Below is Final Blended file on the top layer in Photoshop with all the sharpest sections of each Layer (masked) below the final layer.
I use this technique with my macro images mainly to get the greatest detail on my main subject and the softest backgrounds behind them. You can also control how much sharpness you have on your subject and where the softness starts. With practice the results get more reliable for what you are envisioning when you are photographing them. Also you can change your mind after you captured the series and have the detail or less detail where you want it while you are adjusting your files.
