About the Image(s)

For the last 3 years, I have been visiting the only rainforest in south India - "Agumbe", during monsoon season when it rains all the time. Though it's a challenging environment to shoot any macro, it offers a great opportunity with so many subjects to shoot. One of the main subject to shoot in Agumbe are the snakes, in specific the "King Cobra". Agumbe is the house for this snake, which is one of the more deadly snakes in the world. Let me get back to the image now, it was shot during my visit to this rainforest this monsoon in July. This was a small butterfly, the size of a regular size thumb and was really attractive due to the contrast color of the butterfly and the leaf on which it was sitting, so I went ahead and captured it.

Here I used my Canon 7D Mark II with 100mm f2.8 Lens, shot at 1/160 at f5.0 and 800 ISO

For Post Processing I used Adobe Lightroom for processing my images where I Cropped more than 50%; Retouched the usual Tones (Exposure, Contrast, Highlights, Shadow etc) and Presence (Clarity, Dehaze etc) also worked on noise reduction and sharpening.

I have attached both the original, before and after images.

In macro photography we often get seduced by the thought that our images must show the "small things", and so we often try to "stretch" our images to meet that expectation. In this image you started out with an image in which the subject was a rather small part of the image and cropped it bring the subject into more focus on the small subject. Here the result are "OK" (to my eye), but lacks the sharpness and detail that macro photography is known for. Most of the subject is in focus, but we loose detail in the back wing and back legs.

Here you have discovered an important issue with macro photography. That being the challenge of getting everything in focus (or insufficient "depth-of-filed).

Images where the subject is larger than the camera sensor (roughly the size of a postage stamp) decreasing the aperture (increasing the f stop number ) in impact and increase the apparent depth of filed. Photography of these size subjects is often referred to as "Close-up Photography". When the subject is smaller than the camera sensor is often referred to as "Macro Photography", and here decreasing the aperture has little or no effect upon increasing your depth-of-field. This effect becomes more pronounced as you increase your magnification. That is when we often need to try other techniques (such as focus stacking) to give us sharp magnified images. In this image you are bordering on that transition point, so getting sufficient detail across the entire subject is challenging.

Perhaps if you were able to get closer to make more of the subject fill the frame, more detail and micro contrast within your subject might result. However, you also run the risk of scaring the critter away. That is where higher focal length macro lenses (150 - 180 mm or so) come into play. With these lens you get greater magnification from larger distances, at time essential when attempting to capture skittish subjects.

Welcome to the world of Macro photography. Hang in there and keep on trying. Thant is how we discover and overcome the challenges in this field.

Just another suggestion. The latest technique is focus stacking. You need a tripod and a camera with the ability to focus manually. If You might also want to use the smallest possible aperture. (too small, and you will distortion.) One of my friends gets excellent results with a point & shoot. See Charlie's explanation above. Your photographic goals and budget will determine your equipment.

My personal goal, is to have fun.   Posted: 01/23/2020 18:16:49
