To many, macro photography deals with creating images of very small subjects and revealing fine detail, detail that may not be visible to the naked eye. Using a lens that goes at least to 1:1 for this type of close-up photography is often done with bugs and butterflies and the like. 1:1 magnification means that the subject will be the same size on the sensor as it was in life. Only true macro lenses can get to 1:1. I like to refer to my style of flower photography as "the softer side of macro." I often use a shallow depth of field and selectively focus on one point of interest in the frame so that that area will be sharp while other elements within the image become softly blurred. Thus, my style of macro photography is not at all a traditional one.------Denise Ippolito I have a video on this subject, and I just posted on YouTube so you can check it out, and you can use this link to share with the people in PSA. -----Mike Moats As you probably know macro and micro are the same things. Macro/microphotography is photography done with a specialty lens for the purpose of making small things big and capturing fine detail. The detail would be very fine because of the specialty lens. Close-up photography is where the subject is very close and fills the frame. It can be done with any lens and doesn’t necessarily make a small thing big or have detail beyond what a standard 50mm lens might give. It can be, for example, a section of a barn that fills a frame because it’s very close-up. Its close-up photography even though the object is not small. -----Pamela Keller, Chair of Art Department, Athens State University Macro is anything that is 1x magnification or greater. Everything else would be close-up.------Blake Rudis

Hello everyone:
After about five years focusing on macro / close-up photography, effective today, July 1, 2018, I am leaving Group 63 to pursuit different interesting photography areas and to write more articles for the PSA Journal. I enjoyed sharing experience with you. I wish you all the best.

Thread Title: Sharpening Question

Charles Gattis   Charles Gattis
One question I have for everyone is, "How do you know when you have oversharpened the image?" I usually look for weird artifacts that look like small lines, something like snakes, when I look very close at the image. Sometimes these don't appear until I zoom in extremely close. What do you look for in over sharpening? I asked this because our judge for my camera club's competition said of last month's entries, that "Most of the ones in the digital competition were oversharpened, some extremely." He didn't have the same comment about the print competition. I know there is a difference, but again my question is what do you look for?   Posted: 10/17/2017 08:45:34

Hi Charles: everyone seems to have their favorite method of sharpening an image, and if it works for them in a satisfactory manner so much the better. Regarding over sharpening; if your finished picture has a hard crystallized appearance and a neutral background that seems to have a grainy look, you have likely over sharpened. I shoot in RAW which has no sharpening added, the last adjustment I make is adding some sharpness. If you enlarge the image to actual pixels or 100% when you add sharpening, you can easily observe the effect on your monitor. If you notice a neutral smooth appearing background becoming somewhat grainy looking you have likely over sharpened, you need to back off the sharpening until your background has a very smooth appearance. It just takes some practice to get it right. I have read JPEG already has a certain amount of sharpening built in, if this is truly the case the JPEG users likely need little sharpening added in post processing. I would like to know how the rest of you approach this situation, perhaps I can pick up a tip from our other members.   Posted: 10/17/2017 17:09:32

Thanks Murphy for the quote. This is pretty much what I look for, though sometimes I zoom to 200% or 400% just to see what effect that has, allowing me to see further into the image. I look for grain, snake looking lines, and just “over crispness” on the sides.   Posted: 10/18/2017 06:32:43

Charles: You mention "Over Crispness"; that is a really good definition of over sharpening an image.   Posted: 10/18/2017 11:54:24

Thread Title: Softer Side of Macro

Murphy Hektner   Murphy Hektner
I certainly agree with Denise Ippolito regarding what she refers to as "the softer side of macro" My October 2017 entry featuring autumn leaves is an example of this approach where everything is not tack sharp. This "softer side of macro" does not work for every subject you may encounter, however once in awhile you will find a subject that it works perfectly on.   Posted: 10/17/2017 01:10:24

Thread Title: Sharpening Macro Photos

How I make my macro pictures sharp?

There are many ways to make pictures sharp. Here is my simple way for getting sharp macro pictures.

1. Using tripod.

About 99 percent of the time a picture is not sharp, it is because our hand and camera are shaking more or less. Therefore, I use a tripod whenever possible and practical. Tripod helps me to keep my camera stable even at a low shutter speed. Tripod also allows me to use low ISO. The pictures will be still likely sharp when they are enlarged if ISO is low.

Another source of vibration is the camera mirror when it flicks up. To avoid this problem all I have to do is to use the MLU button to lock it up. I also use a camera release cable, so I do not have to touch my camera. Post processing is more or less useless if raw pictures are blur. Camera stability is crucial to make pictures sharp.

2. Selecting a right aperture.

I often select a wide aperture whenever I need to blur the background, making a main subject stand out and therefore enhancing the photo sharpness. It should be noted that a too wide aperture will make some details disappear and blur the subject.

3. Using "Clarity", "Contrast", and "Dehaze" functions
In Raw Camera, I use the above functions to enhance the sharpness of the pictures.

4. Using "Highlight / Shadow" function

This function in Photoshop does not always work effectively. But it does not cost me anything to try it.

5. Using Topaz Plug-in to enhance details.

Filter > Topaz > Detail. Then select level: Light or Medium or Strong

6. Using Nick Plug In to sharpen pictures.

Filter > Nick > Sharpen Output. Then select Output sharpening strength level: 0% to 100%. Structure level: 0% to 100%.

7. Using layer mask: optional

Occasionally, I use layer masks to separate a main subject from a background. With two things on different layers, I can make several adjustments on each layer without affecting the other.

Background layer: Blur background, soften its texture, lower brightness, reduce color saturation.

Subject layer: sharpen subject, increase brightness, enhance color and details.

Thread Title: Definition of Macro

Charles Gattis   Charles Gattis
I want to begin placing here some extra material that we can share together. And to begin, I thought we might work on some "definition" of Macro photography, since that often comes up in our group. In order to help us out, I asked several "teachers" of art and photography to give me their off the cuff definition of Macro Photography. I'll share each one here as a separate submission.   Posted: 06/25/2017 21:38:58

When I asked Mike Moats to give me his definition, this is how he replied:

I'm sorry to tell you that you will have to copy and paste the url into your browser, but I promise you, the video is well worth watching.
