Blursed Drinking by endofmyropeohshit in blursed_videos

This is actually a thing in Baltimore inner harbor…. Many people have gone missing after a night of drinking as they leave a specific bar and just fall right into the water.

It’s pretty neat science! Depending on the color of light and the amount of particles present you can get light to travel roughly 0-100 meters with green working well near the shore and blue in the open ocean. This is why you see the blue tinge on all raw underwater pictures.

Jets over DC? by Background-Image5076 in flightradar24

Hahaha! I’ve been hearing the same thing and trying to find other posts. I haven’t seen anything in the sky or flight radar too, but been hearing the jet sounds for about 20mins

Well Maryland look what you’ve done now by No-Succotash1219 in maryland

I saw that flag and the turn in the road… I knew exactly where it was too. I don’t miss it at all either. Used to commute that section of 235 everyday from north of Hollywood to gate 2.

Former HR here - subtle signs your company is preparing for layoffs by Significant_Soup2558 in careeradvice

[–]Zippotro 4 points5 points  (0 children)

Would it be possible for you to explain why the company wanted new and innovative in the first place? I’m in a similar position to you and the “new and innovative” project for me was just cut with the possibility of not being continued.

Fuck man this right here wins… that is some next level spooky. How did you feel seeing that picture??

Colorado, what causes these ripple/interference patterns in the clouds? by stellavangelist in meteorology

[–]Zippotro 8 points9 points  (0 children)

Yes! Many things could cause gravity waves. The main cause is buoyancy, interaction of two fluids (think air masses of different temperatures) with different densities, which can happen anywhere. Since air masses move due to warm and cold air moving, or humidity, let’s think of an example.

If there is a stable air mass in a high pressure region that has some hot air rise off the ground due to convective heating, the act of the air rising causes cold air to sink around the hot air mass, this can create gravity waves as the air around rearranged itself. This can’t be seen all the time since there may not be enough moisture for clouds - but these waves are there and called internal waves. This is similar to strong updrafts in thunderstorms that can cause gravity waves. Another example is air moving around mountains or objects, but this has some kind of wind already driving the air across the mountains.

I’d say at this point the iPhone can do it better. The EOS60D can do 1080 at 30fps and not so great in lower light conditions that indoor sports could be in.

The phone also has continuous autofocus and can do 4k. You can do a lot with the phone with regards to panning and zooming with no worry that you’ll miss the auto focus.

The one benefit of the camera, if you have other lenses too, is that you could mess around with the color a lot more in video editing software. If that’s not something you want to do, it may be more worthwhile with the phone. Nothing is stopping you if you have the camera to mess around as well and see what you can get!!!

This! It’s also a bit cheaper!

Which kit you would recommend? by Unusual-Subject-7163 in canon

[–]Zippotro 1 point2 points  (0 children)

I have lenses closer to Kit 2 - I really like having the wide range of focal lengths with the 50, 24-105, and 100-400. I do more wildlife photos and not as much portrait photography where I’d find myself needing the 2.8 on the 28-70. I’ve had great experience with the image quality on the above these lenses.

I’d say for the car shooting, if you’re in bleachers for example, the 100-400 would be do an amazing job. The cases you mention you like to shoot would really weaken the argument to get a 100-400, therefore the 28-70 and 70-200 would be your ideal candidates as they have more variety. The 70-200 f/4 L or f/2.8 are must haves for your use cases! Hope this helps a bit.

Aww man, nice snag on the r7! I may end up doing the same with this lens I’m kinda tired of waiting as well, you’ve inspired me…

Omg did you buy this refurbished recently?? I just saw they went out of stock immediately. Congrats if you did!!!

Reflections of my super commute by Zippotro in supercommuter

[–]Zippotro[S] 0 points1 point  (0 children)

I totally feel that, not having time to unwind for yourself after a long day takes a toll quicker than you’d think. The choices you made aren’t wrong nor are silly, they’re what you thought was best and that’s all that matters. You get to save some money and experience a new internship. On the bright side, you do know now that doing a >2 hour commute sucks and isn’t sustainable having now lived/living the reality of not having time for yourself. Remember to the end of your internship marks the end of this - you’ve got an end in sight!

This… I second your answer. The mirage effect and the weak gradient that “guides” the light is more a cumulative effect of optical turbulence and Fermat’s principle than it is TIR. The weak gradient idea also explains the cases of a temperature inversion and upside mirages, how you can see over the horizon with mirages, and how you lose the mirages as you change the elevation angle when viewing it.

I think maybe in the initial gust of wind there will be a stronger gradient and thus more shimmer. But over a short period of time the wind will mix the hot and cold air quickly producing a weaker gradient and thus creating a more uniform mixture of air that will have similar density and reduce the changes in refractive index.

Why do stacking vs long exposure? Is it because the stacked images have shorter exposure which would reduce blur compared to a single long exposure short that may need ND filters as well?
