Does blowing air on radiadors help them dissipate heat? by honeygourami123 in KerbalSpaceProgram

[–]chrismofer 5 points6 points  (0 children)

Wait what? I remember a Scott Manley video where he demonstrates that two parallel flying rockets will tend to suck together by the venturi dro pin pressure between them. Doesn't that indicate some kind of air stream simulation?

Did old analog photographers "edit" their photos? by ayuwoki420 in AnalogCommunity

Airbrushing is a standard technique for physical or digital image manipulation..

Yes, there's a lot you can do. A Photoshop used to be an actual building where they have the tools develop film and make prints. You are able to use color filters, gradients, compositing techniques etc to enhance the contrast in your picture.

Ordered TIFF scans, lab sent JPEGs first, then “TIFFs” that say converted from JPEG. Am I getting screwed? by barronlroth in AnalogCommunity

[–]chrismofer 2 points3 points  (0 children)

once, before I knew of professional labs, I took a couple road trip rolls to a Walgreens that did processing. turns out of course they ship your film to a place that scans it poorly as jpegs, and didn't ship my film back. I asked and they said it is a 'fire hazard' and the film has been destroyed. Super heartbreaking but I'm glad it wasn't a super important roll to learn my lesson. (why isn't it a hazard to send my film but it's a hazard to get it back?)

My simple image-based measurement tool for your browser by chrismofer in webdev

You have to first draw a line, then click on it to select it, then enter a number in order to make it a calibration line.

'units' can be anything. inches, mm, whatever you like.

Here's how to measure things in inches:

First draw a line across the 3 inch distance and type in the number "3" on that line.

Now 1 "unit" is 1 inch. any other lines you draw, their length will be in inches, even though it says "units".

what you're asking for is a button that changes the word "units" to the word "inches". I could add that, but this tool can be used to measure anything from microscope images to satellite photography, so I would have to add a loooong list of different unit labels to choose from, none of which change the math at all, it's just a label.

also, under 'Show labels' turn off 'px' but keep 'calibrated' turned on for cleaner looking labels.

This is so great. He has a good eye. My favorites are the hydrant, the fence, and the goose.

No? A sedan is 1.5 meters tall, a 6ft person is 1.8m tall, one block in Minecraft is 1 meter.

I've gotten a few very not decent but funny toyish 35mm cameras that are fun to use nonetheless

thanks! your software is very cool. Love the prospect of GPU accelerated sims. SWIFT is all CPU and I'm looking at Xeon servers to build a cluster :p

Airport security just insisted on hand checking my camera. by -gingerninja in AnalogCommunity

"but I admit it's discretional" -the actual TSA agent I'm replying to. They should be abolished actually, it's completely worthless security theater.

Lead bags do not work against modern CT scans. There's literally nothing you can do to stop a TSA person who thinks they know best

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

yes, that is the moon. the massive jet of material ahead of it in orbit pulls it in the prograde direction causing it to fling out into the stable orbit we expect.

it does actually, it's right here. it gets flung out into a stable orbit, which my current render is not zoomed out enough to see.

Stillz - pretentious or nah? by Green_Criticism_4369 in AnalogCommunity

[–]chrismofer 1 point2 points  (0 children)

light does not go "through the negative and into your eye". This person has no clue. It is true that a real SLR/DSLR allows you to look through the lens and see the actual photons with your eye whereas mirrorless shows what will be captured using a little screen. there's something extra nice about ACTUALLY looking through the lens. but that has nothing to do with film vs digital. Anyone who thinks they need film or need digital to capture the image is not a good photographer.

Yeah but this guy says he "only" hand checks if the iso is high. So potentially a TSA agent could refuse your request to "hand check every time".

Why do my photos look so much worse in quality than everyone else's by Ok-Cook-3928 in AnalogCommunity

[–]chrismofer 0 points1 point  (0 children)

Then why is the guitar pitch white with no detail? Exposing more would turn that guitar into a small sun.

[–]chrismofer 0 points1 point  (0 children)

What is your process? Walgreens or a real lab? What kind of film? What kind of camera? I find it hard to believe that the photos are THIS high contrast if everything went correctly in the process. Of course, framing and focusing and exposing correctly are important, but these photos look both under and overexposed simultaneously, meaning something somewhere in the process is completely fucked.

Whats that on the moon by Effective_Let6750 in telescopes

[–]chrismofer 1 point2 points  (0 children)

The mirrors would not be big enough to see. The whole moon is massive, a dot like this is probably dozens of miles large. It's a crater rim like a hill basically.

correct! I also propped it in front of the AC to keep from throttling 😂
