I don’t shoot a lot. I use 64GB cards in both slots and since I use two bodies that has been enough. But I do carry spare cards just in case.

Hope your luck continues. True, the odds are quite low of a problem, but they are nonzero.

Long bursts are generally wasteful in my opinion (I don't do wildlife or sports). Not only does it fill your card with useless images, you have to spend the time to sort them out later. I have a couple cases where I find it essential to shoot bursts, but I generally limit them to 3-4 shots/burst. It really depends on the subject.

The amount of time required is why the camera has a buffer.

But of course my workflow may not fit your practice.

Out in the field, tethered isn't an option and I don't operate in a studio. So I opt for dual slot backup.

Congratulations on your luck, that you never had to back anything up.

I use two slots. I shoot raw only and the second slot is backup.

This is insurance. I have on occasion had one bad file on a card but have never had a whole card fail. But with two slots on backup loss of a whole card is less likely to happen.

The possibility of corruption of the data from one card is nonzero in several ways: It can get corrupted in the camera; It can get corrupted in the card reader; It can get corrupted in the computer. A line glitch during transfer can do the job. If I were to use one card raw and one jpg I would use the raw card to download my images. If those images got corrupted in any way, all I would have to work with is the other card with the jpg images. I lose the raw data. So I use the two slots in backup mode to avoid that possibility.

It's all in how you value your images. If your images are easily replicated, there is no need for insurance. But in my experience repeatable images are rare. If all you do is static scenes, fine. But with anything dynamic, all your images have some value and deserve backup at the earliest opportunity.

All depends on your definition of 'few'.

My way, of course.

You want to verify that the card downloaded properly and you have backed up the data in your computer. Only then should you clean the cards.

So?

So change the entry requirement for your group to include "Guys from college" or even "Guys from life". Surely if your high school guys are mostly gone you have met new people over the years.

I had a desktop with 3 monitors at one time. Lightroom, Photoshop, and Other.

But then I moved and didn't have desk space for more than two.

But then the desktop died so I was working on the laptops (1 Win10, 1 MacBook).

But we're in the process of moving again to a larger space so I'm looking forward to 2 or 3 monitors (or maybe even more?). I have 2 extra monitors that my MacBook will handle.

My old film cameras had lenses that for the most part were f/3.5 or smaller. When I first started working with DSLRs I thought that the larger apertures would be significantly better when it came to my photography. Let in more light and I can get better shots (faster shutter speeds to combat shaky hands or moving subjects). So I got a 50mm f/1.4. And other lenses in my collection started at f/2.8.

Fast forward a few years and I had 10K images in my photopile. I found a utility that would take them all and show me the distribution of various parameters in the capture of those images. I found that the extrema of focal lengths prevailed, a lot of wide angle and a lot of telephoto and a moderate amount of midrange focal lengths. But when it came down to aperture, there was a peak in the f/5.6-8 range and very few shots at apertures less than f/3.5 (or more then f/16). I used f/1.4, but the number of keepers I got at that aperture was very small.

Today, the availability of high quality high ISO images makes it possible to get photos without resorting to large apertures. And the DOF is much larger with the smaller apertures. Postprocessing techniques make it possible to reduce the DOF on an image, but it's more difficult to increase DOF, so midrange apertures are preferable in my opinion. I'd rather have too large a DOF than too small.

and 8-track and punch cards and paper tape and wax cylinders and daguerrotypes and tile mosaics and cave paintings and.......................

Just think: even M-disks will be obsolete someday (less than 1000 years from now).

I had a cat that would catch small rodents. I never saw a live rodent in the house while he lasted. However, we frequently found remains.

Actually when I was 78 I got married again.

It ain’t over ‘til it’s over.

We try to get together as a group once a year or so.
