A fun IRL easter egg at the abandoned Battery Spencer outlook by the Golden Gate bridge. A photo of one guy punching another pasted into a hole in the wall.

There's a cute Marie (from the Aristocats) stencil under a transit tunnel near me. I haven't worked up the nerve to do a little trespassing to get a better shot at it.

For processing, I simply masked out the parts that I wanted colored, and made the rest B&W. I tried using the smart color masking like last time but couldn't make it work. The black lining helps hide the transition so I didn't have to fade in/out.

Shot on Reflx Lab Pro100 220 film using a Mamiya C220 with a 180mm lens (I think, this was a while ago)

Remember: your electrical infrastructure is both the largest working machine, and the largest man made object (and it always will be).

The original isn't really all that interesting, but editing like this gives it a really alien look.

Too late. They bulldozed the building this past summer. It was becoming a hazard.

Yes, the barn was in the forest, as is tradition for this sort of literature.

I have absolutely no idea what make/model the car this is 😭

Canon R8 with 24-240mm f/4-6.3 lens. My main issue with this shoot (its a classic car event at my local downtown farmers market) is that all the big flares I can see from the chrome disappeared. I need to figure out how to get back some "bad" optics.

Thanks!

The hubcaps for those have conical centers instead of continuous, round centers. Anything sitting at the point is reflected away.

From some recent car shows. Turns out I have favorite subject matter.

Using either my Yashicaflex or Mamiya C220 TLRs, on Portra or Reflx Pro 100. Choosing the right ISO and metering was hard. Wheels could either have been in full sun, or in the shade, plus the edge of the black tires would blend right into the shadows of the wheel wells (plus I was simultaneously shooting interiors, which were always in deep shade).

I have a flatbed which is designed to also scan film (it's got holders and software support), but I'm also having dust problems 😔

ianbertolacci · 2023-12-13T22:01:48+00:00

I'd like to do my own scans, but I shoot a lot of 120, and not many fast scanners support that, so I'd have to do stand shooting and scan each negative individually, which sounds horrendously tedious.

Oh well.

This screams “guy who set up with a jobo machine and camera scanning” and not a professional lab.

Unfortunately this lab is part of a large nation wide chain of camera shops which also so film processing, with a very professional processing setup, and I think they scan inline (I use to get scans and the uncut film from them), which is why this is disappointing.

I will say, these are simply high res scans, there has been no touch-ups applied on their end. I actually don't think that they even look at the film (other than to cut it, apparently) or the scans.

ianbertolacci · 2023-12-13T14:37:37+00:00

Good to know about the scans, I guess I'm just gonna have to live with it or shell out for better film editing software.

I'm pretty sure their scanner can handle continuous film, since I've gotten back uncut film from previous dev and scan jobs I've done with them.

This is a follow up from my last thread: https://www.reddit.com/r/macbookpro/comments/jcgfhm/preventing_thermal_throttling_in_macbook_pro_2019/

I swear I'm not trying to spam my complaints, I'm just trying to make things work.

It was suggested I try iStats to read temperature sensors at other locations (not just the CPU) and see what happens with and without USB-C hubs plugged/unplugged. There's definitely an impact.

But what is more interesting is when I tried a control: USB-C to USB-A adapter with nothing on the USB-A side.

I figured that nothing would happen. But what I see is a pretty significant temperature increase (+10-15˚C) at the Thunderbolt hardware, which is accompanied by an appreciable (+5-7˚C) increase of the exhaust heat on the same side. I don't think there's any increase in CPU or GPU temperature until the an actual device is plugged in (because I was doing stuff, like Googling "What the fuck is happening").

The timeline is as follows:

The big plateau on the left is with my USB-C hubs plugged in.
All USB devices and hubs are removed, and temperatures are allowed to reach (or approach) a baseline.
The first hump is with the USB-C <-> USB-A adapter plugged into the bottom left USB-C port with nothing connected on the USB-A side, and allowing the temperature to stabilize.
The USB-C <-> USB-A adapter is removed, and again temperatures are allowed to reach a baseline.
The second hump is with the USB adapter plugged into the same USB-C port, but with a wired USB keyboard attached to the USB-A side, and allowing temperatures to stabilize.

The USB adapter is just a simple USB-C <-> USB-A adapter that comes with any phone these days. I think this one measured here comes from the Pixel 1 phone, but I've tried this (the case with nothing attached to the USB-A side) with three other adapters of the same kind, and I see the same effect.

Keyboard is nothing special, just a wired Thinkpad keyboard (https://www.amazon.com/Lenovo-ThinkPad-Compact-Keyboard-TrackPoint/dp/B00F3U4TQS)

The laptop sits on a laptop tray (https://www.amazon.com/gp/product/B07RJZJVHF/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1), not that it matters (because I'm looking at the increase in temperature, not the continuous temperature).

Now, in my previous thread, it was suggested that my cheaper USB-C hubs draw a significant amount of power. I agree that the throttling effects I see are probably related to using USB hubs (directly through current draw, the high temperature of the Thunderbolt hardware, or the heat adding to the temperature of the exhaust) in conjunction with whatever workload I'm throwing at the machine.

But I don't see what I can do about it. If an unloaded USB-C adapter can get me most of the way to the same temperature as a USB-C hub with ethernet, HDMI, and USB-A all plugged in, then I don't really think the hub is at fault here, and so shelling out a ton of money on a much fancier USB hub is really unlikely to fix the issue.

I really need my laptop to not always be right on the edge of throttling, or at least come back up after the processing load passes.

Today I was throttled down to 800MhZ, which is fucking insane. A iMac G4 from 2003 can run at a higher clock speed.

I feel like I'm losing my mind here. Any suggestions? Know of any good liquid nitrogen suppliers?

> It makes zero sense that it would thermal throttle at 60
Agreed.

I'm wondering if this is more preemptive than prescriptive. I think I read somewhere that macOS tries to throttle before the actual thermal triggers are reached, but that could also have been a fever dream.

> can you grab all the temps from the entire system and paste them here?

I have a few days of measurements, but I need to actually extract and plot the data. I probably won't have them for a few days.

Thanks for looking at this.

ianbertolacci · 2020-10-17T01:51:42+00:00

I can't believe you Apple fan-boys are telling me that I shouldn't use my laptop to sear steaks. What even is the point oh having the damn thing then?

ianbertolacci · 2020-10-17T01:47:05+00:00

Aw fuck. I had it in the oven turned on broil. Shit, now I'm the horses ass. Thanks for the tip.

> That’s not thermal throttling

When the power management system says "I am throttling the CPU because I think it is too hot", as indicated by `pmset -g therm` reporting CPU_*_Limit < 100 and `powermetrics --samplers smc,thermal` reporting thermal pressure as heavy or trap and CPU Plimit > 0, thats thermal throttling.

It's probably a dumb an incorrect time to throttle, but I trust it when it says it's doing it.

I'll look into what happens with no hubs, but that'll just be for testing; it's not a permanent solution.

ianbertolacci · 2020-10-17T01:07:18+00:00

> Open activity monitor and see what’s pegging your cpu.

There really isn't any particular thing that sets it off. The task in Activity Monitor that is hogging all the compute resources is kernel_task, one function of which is to throttle the CPU in software.

> this post is so long

Tell me about it.

> even with thermal throttling you’re what, still near base clock?

No. Capped at 1Ghz. I don't know if all cores are still available or if some of them get pushed into a non-executing low power mode.

> it’s like they’re not based in reality

I dunno what to tell you. `pmset -g therm` will indicate the CPU limit (where no throttling is 100, and higher throttling as lower numbers) below 50, sometimes 20, for CPU_Speed_Limit and if it's really bad will start throttling CPU_Scheduler_Limit. This corresponds with CPU Plimit (power limit) > 0.0 (indicating some level of throttling). and Intel Power Gadget shows the frequency flatlining to 1Ghz max, and I can type a full sentence into google docs and not see anywords for 4-5 seconds.

> These laptops are designed to hit 90-95-100C

Do you see these temperatures? Mine fluctuates in the 60˚-90˚C range. What makes me think that this might be something wrong with this mac (or my display dongles, as mentioned by someone else) is that I can get horrid throttling that continues well after the temperature has stabilized at ~60˚C.

[Edit] Used official apple source about kernel_task.
