In this short post I will simply show another example of a deep focus, fisheye capture.
As in the last post, the image was taken with my new TTArtisan's 7.5mm f/2 fisheye lens, set to an f/8 aperture. I also used the CHDK (log) histogram to help me set the exposure.
The focus was set to the minimum focus of 125 mm and, once again, I was content to let the highlights blow out, ie I wasn't trying to also cover the dynamic range of the scene in this test.
As I knew the near field object of interest was important, I made sure that I had 'space' around it, ie for WA post processing.
Using the lens DoF scale I captured three focus brackets, ie from 125mm to infinity:
The above RAWs were first adjusted in Lightroom, ie for WB and highlight recovery etc, and exported into layers in one Photoshop document.
Selecting all three layers I then aligned them and auto focus blended them to arrive at the following:
Here we see the classic fisheye distortion which I then processed using the Photoshop Adaptive WA (AWA) lens filter.
Having placed guidelines throughout the image, identifying horizontal and vertical features, the AWA filter screen looked like this:
You can spend a lot of time at this stage, adjusting the various features you wish to see straight, and you need to be prepared to 'call it a day' when you see features interacting, as you will not be able to address every feature perfectly; as you can see below.
After flattening the image and returning to Lightroom, the final step is to crop and tone the image. In this case resulting in the following test result:
With deep focus, wide angle image capture, the image will be more impactful if there is a recognised feature in the near field: in this case a tea bag sachet.
As usual I welcome any feedback on this post or any of my posts.
