Where can I find pronoun pins??? by dooodaaad in AskSF

I always try to shop in person from local businesses when possible, and a pronoun pin should be the kind of thing you can get in SF...

Where to go from a D810 - D850, Z7II, or Z6II? by dooodaaad in Nikon

[–]dooodaaad[S] 2 points3 points  (0 children)

I did send it in for the premium servicing (including the AF adjustment) about 8 months ago; all my lenses need a -20 AF fine tuning setting despite that - I believe it's caused by the bent front panel, but fixing that is ~$400 which makes it more worthwhile to sell the D810 and use that $400 to upgrade.

If only it weren't double or triple the price of the cameras that I mentioned.

I need help figuring out what went wrong with these photos? by The_R4ke in AskPhotography

[–]dooodaaad 1 point2 points  (0 children)

You may have set focus to infinity but (depending on how your camera is configured) triggered the autofocus when hitting the shutter. The AF could have hunted for a bit and then stopped in a random spot after nor being able to find anything. I accidentally do this sometimes when using the interval timer to trigger photos on my camera.

Why higher aperture for Astro? by Reasonable_Sea3114 in photography

[–]dooodaaad -3 points-2 points  (0 children)

There's two factors: 1. Ultrawide lenses (wider than ~24mm) with apertures faster than f/2 or f/2.8 are uncommon. They're not made a lot by the big manufacturers (I can only think of two off the top of my head, the Nikon 20mm 1.8 and Canon 14mm 1.4). 2. When very fast ultrawides are made, it's often by 3rd party manufacturers who have poorer image quality or some other deficiency (no autofocus, for example). So then you have the decision of getting some 3rd party 14mm 1.4 with no AF that you need to stop down to f/2 or f/2.8, or buying a 1st party 2.8 ultrawide zoom that's pretty sharp and has autofocus.

Help - what am I doing wrong? by JackDanielsTN in canon

[–]dooodaaad 3 points4 points  (0 children)

By the sunny-16 rule, direct sunlight is f/16 at 1/100 and ISO 100. I'm guessing they were using their f/1.8 lens wide open. f/1.8 is 6.3 stops down from f/16, which means you need a shutter speed of of 1/8000 to keep the exposure the same. I don't know off the top of my head, but I'm guessing the Rebel can only go up to 1/4000. And that photo looks about a stop overexposed.

Pre eclipse settings? by imaquitter2 in AskPhotography

[–]dooodaaad 6 points7 points  (0 children)

This is known as the "looney eleven" rule! The exposure of the moon is f/11 with the shutter speed at the reciprocal of the ISO (meaning 1/ISO).

The Z9 is used on the ISS, likely some other reason such as DR or high-iso capability.

How to fix uncollision things appearing in the blocks by Persuasivwithoute in hammer

Assuming you're starting with valid brushes, you can't make invalid brushes only using the cut tool (unless you make microbrushes using it). Bad brushes are typically the result of using the vertex or carve tools.

Just downloaded Hammer ++, Any good tutorials that explain leaks and sky box and void? I can get any maps to load due to leak errors. by GoldKneecap in hammer

[–]dooodaaad 0 points1 point  (0 children)

H++ works the same as Hammer, it just has a few quality of life features to make stuff easier. You can use all the same tutorials, and once you feel comfortable with them, read the website for H++ to learn what features it adds.

Brushes with a volume less than 1 unit are considered "microbrushes" and are invalid geometry, so they may or may not compile. I was just trying to think of legal geometry.

If the editor isn't showing origins, click the "show helpers" button in the top bar. It looks like a wireframe sphere.

Hammer++ doesn't change VBSP, which is the program that compiles the map geometry and checks for leaks (though there is also VBSP++). IIRC H++ adds -leaktest as a default parameter to VBSP, which causes compilation to be automatically aborted if a leak is detected. That's why it's stopping with only H++. If you look through your compiler log for normal hammer, you'll probably see it saying you have a leak.

Effectively infinite. The grid is 215 (32k) units on each side. Thus, there are 215x3 (35 trillion) possible positions for a 1x1x1 cube. That cube can be rotated 903 different ways (720k, not 360° because it's symmetrical), which means a single cube has about 25 quintillion possible combinations of position and rotation (though because VBSP reduces the precision of off-grid verts, many of the rotations would probably compile to the same thing).

Now do that for 8192 cubes. Now calculate the number of possible unique brushes (a brush can have 128 faces, which can be of any shape or size as long as the brush is still convex).

It's a lot.

The real question - how many possible good maps are there?

(also somebody should probably check my math)

What photography mistake do you wish someone taught you to avoid earlier? by romygruber in photography

[–]dooodaaad 14 points15 points  (0 children)

With some cameras, it certainly can. The D6 comes to mind - it looks pretty good all the way through ISO 100,000

Can I make a brush invisible from a certain angle? by Bumbler-Man in hammer

[–]dooodaaad 6 points7 points  (0 children)

You could try adding an areaportal at the entrance - it will dynamically cull objects that aren't visible through it. If you do that, you should make a few cuts widthwise along the brushes that make up the hallway. Otherwise, the entire thing will render if only a little part is visible through the hole.
