I am occasionally asked how I come up with topics to discuss during my twice weekly livestreams. The topics come from several different sources. Most often, I am answering a question that was brought up by one of my students or asked by a livestream participant. If, when thinking about the question, I can expand on the topic to include interesting background and details, it will often become my subject for the week. But I also keep an ever-growing list of promising subjects that occur to me during my own exploration of macro photography and associated disciplines. The beauty of macro photography is that there are more fascinating topics to explore than I could cram into a lifetime of livestreams.
I try not to repeat myself and avoid talking about the same topic twice in the same year, and even when I do return to a previous conversation I try to emphasize information that has not been covered. I need to bear in mind that new viewers are going the streams every week and for many of them this may be the first time they have encountered the topic. Balancing the needs of the newcomer to macro with the seasoned experts that are also in the audience every week is the hardest part of programming these events.
This week, for example, I am breaking from my usual practice of finding a common theme for both livestreams and instead will be addressing two distinctly different topics that came up in conversation over the preceding week. This has the advantage of keeping things interesting and relevant to more viewers, while keeping the process interesting for me at the same time.
On Tuesday I am going to talk about the use of polarized light in macro photography. I don’t think I have ever discussed this subject as I plan to in this livestream. The question that prompted this was a practical one - “when should be using polarizing filters in macro photography?” - and to answer that I need to explain a little about polarized light. So I will open with a discussion about light in general and the concept of polarity in the context of visible light. When we understand the nature of light and see how it can be polarized, everything else I talk about should make a lot more sense. For example I will explain the difference between using a polarized light source and polarizing the light that enters our camera through a polarizing filter. When do we want to use the former, when the latter, and I will introduce the concept of using both.
For a subject to be useful for your photography it needs to have some practical application, so I will describe the various types of polarizing filters and give step by step recommendations on how they are used. By the end of the hour you should have everything you need to make wise decision about when and how to use polarization as well as information on the best brands of polarizing filters to look for. B&H carries a wide selection of the very best circular polarizing filters - you can find them here - https://www.bhphotovideo.com/c/search?Ntt=circular%20polarizing%20filters&N=0&InitialSearch=yes&sts=ps&BI=23366&KBID=28903&SID=DFF&DFF=d50

On Thursday we are going to look at something completely different that I think should be of interest to many of you. What is the best tripod head for use in macro photography? I don’t think I have ever talked about this in any depth but it is quite interesting. For one thing, there are a lot more options than most people might be aware of, and they are not all equally ideal for close up work. I will describe all the different ways in which a camera can be mounted to a tripod (monopod, ground pod, camera stand, etc.) and discuss the relative merits and drawbacks of each. Based on my own experience I will make specific recommendations for each time of head and explain why I use each of them.
If you are thinking about adding or replacing a tripod head in your bag, here are a few of the products that I recommend and will be talking about during the livestream.
When it comes to ball heads you will have a hard time finding anything more versatile and well constructed than the Really Right Stuff BH55, available from B&H - https://www.bhphotovideo.com/c/product/1301057-REG/really_right_stuff_bh_55_pro_bh_55_ballhead_with_full_size.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x781162/SID/DFF
Another contender at the top of the stack is the incredible Novoflex Magic Ball - a different take on the ball head but one that many of the best macro photographers swear by - https://www.bhphotovideo.com/c/product/153279-REG/Novoflex_MB_Magic_Ball_with_Socket.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x1596924/SID/DFF
For the more budget conscious photographer, Sirui makes a really lovely low profile ball head, the AM40 that is a little smaller than the RRS, but a lot less expensive - https://amzn.to/4hfVBVG
In the geared head category you will not find a better affordable three-way head than the Benro GD3WH that I use. I have ben using this for at least 6 years and I love it - https://amzn.to/3AaA93v
Another option if you jus have to have the best geared head on the planet is the original Arca Swiss cube, available from B&H - https://www.bhphotovideo.com/c/product/1373798-REG/arca_swiss_8501303_1_cube_c1_gp_geared.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x861127/SID/DFF
I think a very fine alternative at a lower price point is the new Leofoto geared head, also from B&H - https://www.bhphotovideo.com/c/product/1796458-REG/leofoto_gw_01_3_way_geared_head.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x1340748/SID/DFF
For anyone wanting a video friendly fluid head, a very attractive option is the new Neewer, shown above. It is sturdy and easy to use, while also being very affordable - https://amzn.to/3YcPZmo
The SmallRig DH10 is another excellent choice - https://amzn.to/4f3DvEm
I recommend a two axis head for use with a monopod and one of the best for the price is the Sunwayfoto DT-03S - https://amzn.to/3BTe0HA
B&H has a wide selection of other monopod heads - https://www.bhphotovideo.com/c/search?Ntt=monopod%20head&N=0&InitialSearch=yes&sts=ps&BI=23366&KBID=28903&SID=DFF&DFF=d50

Macro photography is unique in a number of ways but one feature that makes it particularly exciting for me is the almost infinite variety of special optics that can be adapted for use at magnification. Macro lenses are, of course, purpose built for close-up imaging and, as you would expect, they run the gamut from terrible to superb, with most falling somewhere in the middle. But what is even more interesting to me are the specialized lenses, usually designed for some specific purpose other than macro photography, that can be adapted for use as macro lenses. Some examples include optics designed for use as scanner lenses, close-up diopters, bellows lenses, enlarger lenses and a host of specialized industrial lenses. In each of these categories there are lenses that perform particularly well when adapted for macro. But there are a handful of lenses that really deserve to be placed in a special category all on their own because they set the standards by which other lenses or lens combinations are measured. These are the lenses I want to talk about this week and I call them Exotic Optics.
Exotic Optics is a somewhat arbitrary designation and you will see it used to describe lenses like Laowa’s probes, Nikon PC (Perspective Control) tilt/shift lenses, and Canon’s MPE-65 variable magnification lens, among others. But for the sake of this discussion I am going to define Exotic Optics to exclude these consumer-type lenses. The lenses I want to talk about are in a subgroup of optics that are relatively rare, typically very expensive, not designed or marketed for use on standard camera equipment, and were developed with a very specific use-case in mind. The one thing that all these lenses have in common is that they are highly sought after by macro photographers because of their extraordinary performance. These lenses are usually of a fixed focal length and typically, though not always, have a fixed magnification ratio. Many are designed to be used wide open, and perform best with a wide aperture. None of them come with a standard camera mount and some require complicated special adapter setups to use with a consumer camera.
Most of the lenses I will be talking about are “industrial lenses”, designed for use in a variety of industrial applications, from making prints in the motion picture industry, to scanning silicon wafers for quality control in computer chip fabrication. They are used in machine vision applications where the highest possible clarity and resolution are required. Because they are not made for consumer applications they frequently lack specialized coatings on the glass elements, and often have no external controls or markings. They are possibly the only lenses that are more intimidating for mere mortals to use than microscope objectives.
I must make a confession here… While I have made it my business to learn all I can about these rare and expensive lenses, I do not own any of them. The lenses I am going to talk about are on my wish list list and are even listed in the order that they appear on that list. Some of these lenses are not absurdly costly, but the less expensive exotics also seem to be the hardest ones to find on the used market. With almost no exception, these lenses must be sourced on the used market, or occasionally through an industrial surplus outlet. Virtually never would we find these lenses in a consumer retail outlet, and many of them have been out of production for decades. The selection of lenses I am going to talk about are all lenses that I have studied in detail and many of them have been carefully evaluated and written about on specialized websites like Closeuphotography.com (Robert O’tool), Photomacrography.net (Rik Littlefield), and Coin Imaging (various), and I know many individuals who own one or more of these Exotic Optics. For example, the cover of Tuesday’s livestream shows a PN150 2.8 Printing Nikkor belonging to movie industry-insider, Mike Kanfer.
The lenses that I am going to focus on are listed below:
1) Printing Nikkor PN150 f/2.8
2) Printing Nikkor PN105 f/2.8
3) Printing Nikkor PN95 f/2.8
4) Mejiro Genossen FLO530 f/4.0 110mm
5) Etendue Mejiro OTH100 90mm f/5.6
6) Schneider Kreuznach Macro Varon CAS 85 f/4.5
7) Rodenstock APO-Rodagon-D 75mm f/4.5
8) Leica Z-Macro 100mm f/4
9) Zeiss -S-Planar 60mm f/4
10) Kowa LM50HC 50mm f/2.0
11) Computar F-mount 100mm f/2.8
You will notice that I have not included any of the excellent microscope objectives that could easily qualify for a spot on this list. That is mostly because we have talked about these lenses often and most of them are used for significantly higher magnification applications than these lenses. The optics I will discuss on Tuesday cover a range of magnifications from 1:4 up to 4X, though most are at or near 1:1. We will talk about the relative merits of each lens, why you might want one, and how much you can expect to pay, should you even be able to find one! The link to the livestream is here…https://youtube.com/live/4cwnV5LPQKw?feature=share
On Thursday we will continue our discussion of lenses by looking at the other end of the macro spectrum - affordable macro lenses. This will include both new and older macro lenses that can be bought new or on the used market at reasonable prices. Some of these lenses will surprise you, especially given the prices. We will stick to actual macro lenses, mostly from well known companies. Here is the link to the livestream…https://youtube.com/live/r8LuzT4lpRQ?feature=share

There was a problem downloading the recorded Episode 7, which is why the video has not yet been posted - I am working on a resolution and hope to have it up soon
On Thursday I talked about good, affordable macro lenses from many different companies - there was a lot of information to cover but here are links to every one of the lenses I talked about:
Key Characteristics to Look for
Focal Length: A range between 60mm and 100mm is ideal for versatility in macro photography. The longer the focal length, the more distance you have from the subject.
Magnification Ratio: All these lenses offer at least 1:1 magnification, crucial for true macro work.
Autofocus vs. Manual: Many affordable lenses are manual, but autofocus can be a bonus if speed is important.
Image Stabilization: Not all lenses have it, but it's a valuable feature for handheld macro photography.
