.. Continued from previous post. (Post 3 out of 3.) Figure 20. "I'm the one they should be scared of ..." This is one of my favorites of the night. Figure 21. Royals. Figure 22. This little guy was adorable. Figure 23. Nicely coordinated. Figure 24. Central Courthouse. It's attached to...

... Continued from previous post. (Post 2 out of 3) Figure 11. Angel and devil scrutinizing the evening's options. Figure 12. I missed focus by about a centimeter and a half on this shot. The Halloween eeriness shown through anyway. Figure 13. Corridor in the Myst Lounge. I'm pretty sure...

2025 Halloween pics here (post 1 out of 3). I brought my Noctilux 50mm f/0.95 ASPH to downtown San Diego, Gaslamp Quarter, for this. There are better lenses for the task. I know that. I knew I would blow potentially good shots by mis-focusing, or just miss them completely due to having a...

What's more I wonder how many youngins even know what C: is, now with everything on cell phones and such.

Testing out a new lens. The Leica Noctilux-M 50mm f/0.95 ASPH. I call it the holy hand grenade. It's big, heavy, and unwieldy compared to other rangefinder M lenses, can't focus closer than 1 meter, costs as much as a car, and suffers significantly from chromatic aberrations when wide open...

I don't know the origin either. At this point I can only speculate. But I'm confident that it's possible to find the origin/root cause with proper experimentation, perhaps starting with very controlled conditions. Bound the problem. For example, start with a batch of flats and stack them to...

In addition to ideas in previous posts (e.g., make sure focus, rotation, etc. is consistent between lights and flats), also Make sure that the use of the lens' lens-hood/dew-shield is consistent between lights and flats. For example, if you use lens hood when you take your lights (which you...

So I was strolling around downtown San Diego the other day (for reasons), and I stumbled across a couple of nice looking strangers in the middle of an intersection. I had my camera in hand (with a 28 mm lens attached) and reflexively snapped off a photo without even really thinking. I have no...

Nice. :smile: (For reference:)

Today's (well, yesterday's) xkcd. Physics Paths (Source: https://xkcd.com/3155/)

I've switched back and forth between hard-'g' and soft-'g'. The original team who developed the gif standard preferred the soft-'g', So now I'm inclined to give them the benefit of the doubt. Although to my ears, both are fine choices. Whatever floats your boat. I'll personally tailor my...

Mine too. I have an acquaintance on social media who, unfortunately, proudly refers to himself as a "sh*t poster." That's someone who post lots of shock value memes, images, and other stuff regardless of truthfulness or legitimacy. I've gotten into the habit of periodically, temporary-blocking...

I spent the last 5 minutes trying to track down a news report of police chasing a dog on a scooter. I came up with nothing outside of several different (but similar in concept) videos on social media. This leads me to suspect that this is an AI generated video.

As I always say, no matter how tempting, and no matter how cute and cuddly they look, do not eat the bats. :smile:
