Short Focus - A Primer

All my clocks are broken. Or so I thought on Sunday morning, for maybe the 120th time in my life. Of course they are not broken and the sun is still above the horizon at 5:30 PM on this first Sunday evening of “normal” time. Another weekend has flashed past during which I developed a revolting sinus infection (my first) and built a bunch of photography gadgets. I also spent a little time thinking hard about whether or not I should wade into the murky waters of small-scale manufacture and actually try to make a little money selling some of this stuff.

A focus block conversion

There are pros and cons, of course. On the plus side, I really enjoy the process of designing, drawing, prototyping, and finishing all these projects. I love testing them and using them, too. I like getting feedback from my friends and working to improve on designs and building approaches. I even enjoy sourcing the best low-cost parts for the projects. Now, a big part of this is that I work on these projects to relax and test myself - the only schedule is the one in my head and I seldom allow my “hobby” to get in the way of my work. But what happens when someone is paying real money for one of these things - how relaxing will the work be then? And then there is the whole money thing. I am not very good about asking people for money because it makes me feel uncomfortable, as does receiving it when I do work up the courage to ask. Becoming a maker and seller of these gadgets would mean I would have to do this a lot (hopefully), and that sounds a little scary.

The conversion motorized

Neither the focus block stacking device nor the cross polarizer platform were cheap to make. That is because neither was close to finished until I had drawn, printed and assembled at least half a dozen prototypes - a process taking several weeks and a bunch of parts. But even accounting for my time, they also weren’t that terribly expensive to make either. So, at the end of the day, I am not exactly sure what they are worth, and I absolutely need to know that before I will sell one. I try not to talk about this channel’s finances - it is too embarrassing - but an infusion of profit from something like this would  be most useful and very welcome. Then there is the question of what I should actually try to sell - a complete, ready to use gadget, fully assembled and ready to use? Or a kit, complete with plans and instructions? Or some other hybrid arrangement? I just don’t know.

So I am going to ask you what you think and I would be most grateful for any feedback you can offer. It should go without saying, but this is just me asking you what you think. It is not a solicitation and I will record your feedback without identifying information. If you feel so inclined, please answer a couple of simple questions for me - you can do so in the comment section below this post, or you can contact me in any other way that is convenient. You are also welcome to answer only the parts you want to. Here we go:

1. Would you be interested in buying a fully ready to use cross polarizing birefringent crystal viewer and imaging platform?

2. How much would you consider a fair price to get one?

3. Would you be interested in scoring a microscope focusing attachment to use with your stackShot or WeMacro controller?

4. How much would the whole assembly, not counting a microscope, be worth to you (frame, fine focus interface, Motor, cables)?

5. Would you be interested in getting a free standing, ready to use fine focus device including a microscope focus block and the drive assembly (for use with whatever controller you already have)?

6. How much would that be worth to you?

7. Is there anything else that I have invented/built in the last few years that you would like to have a chance to buy?

8. Any other words of wisdom or encouragement?

the testing platform

Thanks for doing this - I will let you know what the bottom line is in a few days. Now here is a picture of a bridge. No reason.

So what are we up to this week?

On Tuesday, in Macro Talk, I am going to tell you everything you need to know about the technique of short focusing in high magnification macro photography. It is surprisingly straight forward, but can add a very exciting dimension to your use of objectives as camera lenses. I will cover what it is for, how to set up the equipment, the potential problems, and the gear you will need. Then I will tell you exactly how to evaluate and relay lenses that you think may work for short focus and actually walk through the process using one of Susan Seaford’s telephoto Nikon lenses. Fun!

On Thursday we are going to take one more look at the two macro-gadgets I have been working on for the last month and I will complete the circle by giving you step-by-step instructions on how to take full advantage of the two 3D print files that I released earlier today. Literally everything you need to know to build and use both devices for your own rig. Even if you have no interest in building either of them, there will still be a ton of interesting stuff to talk about. Don’t miss this one!

Saturday is Pzoom - a private face to face meeting with my awesome Patreon supporters, where they get to ask questions, lodge complaints, hurl obscenities, and just have a good old time with their host - me! I will have a few surprises for the group and we are going to have a very good time - promise! The invitation is posted over on my Patreon page at www.patreon.com/allanwallsphotography

If you missed the last AfterStack, fear not, as it is now available by following this YouTube link to the recording!

A busy week and a lot to prepare for, so I had better get my skates on! Hope to see you soon! All the best!

The Great Thaw

That is what it feels like, after two sun-filled days with temperatures in the 40’s and low 50’s - what the Middle-Earthers refer to as “warm”. It is not warm, of course, but one could be forgiven for thinking it is after two weeks of soul-destroying single digit highs and digit-destroying sub-zero lows. And some of the ice and snow did melt this afternoon, though not for long - most of the water in Middle Earth has phase-shifted back to the solid form. While not many who know me would accuse me of being prone to optimism, I have come across a silver lining to this meteorological catastrophe called winter. My fear of freezing to death out in the elements has forced me to face up to my fear of freezing to death in this basement, and this has allowed me to attack a few projects that have been somewhat neglected since the beginning of winter, seven years ago. Throwing myself into these projects has renewed my enthusiasm for making stuff, and you know what happens when I get enthusiastic about stuff- I feel duty-bound to get you enthusiastic about stuff too. That is my goal for this, the last week of February, 2025.

Kicking things off on Tuesday I aim going to come at the subject of DIY obliquely, walking you through the steps required to modify your macro platform for use at high magnification and high resolution. At the heart of these modifications is a gadget that, to the best of my knowledge, cannot be purchased but must be constructed. I plan to show you exactly how this is done, from start to finish, in under an hour. The link to this episode of Macro Talk, which starts at 8PM on

On Thursday, in Macro Talk Too, I will come at DIY in macro photography more directly, breaking down the various skills and tools that I believe are worth acquiring, in order to get the most out of our macro photography. I will do this by giving multiple examples of how my growing experience with tools and techniques have paid off in my macro experience over the years. I think it should be a lot of fun and if you would like to join the conversation, here is a link to the livestream on Thursday - https://youtube.com/live/JV1z2k_IatM?feature=share

This is the last week of the February Macro Competition - your pictures must be in before midnight on Friday. The theme for this month is Symmetry and I can’t wait to see what you have come up with! I will announce the theme for March later this week. Saturday is going to be a busy day for me as I will be judging the competition on Saturday while also hosting our first Pzoom meeting of the month. I am trying to come up with a creative way to combine these two activities and I think I may have a workable solution - should be fun!

For anyone who is interested, I placed a bid on a microscope this morning. It is a gorgeous Olympus CX53 fluorescence scope with DIC. It comes with a full complement of high NA objectives, DIC prisms and a multifunction condenser. I has literally everything I want in microscope - but I lost the auction in the last 5 minutes. I’m not really surprised - my bid was ridiculously low for the almost new $20K microscope, so it didn’t take too much to beat it and someone was watching closely. The final price was only $1,700, but that is out of my comfort zone until the IRS has my pound of flesh. You win some, you lose some!

Sorry for the lateness of this post - I lost my whole Monday, helping a friend out of a bind. Tuesday was spent getting my two microscope focusing devices ready to ship to two very patient photographers.

I hope you have a great week and don’t miss Thursday’s livestream - lots of really original stuff to tell you about!
