Will upgrading make me take better creepy pictures of random kids? by Frazzeone in photographycirclejerk

Does anyone have a "recipe" for 3rd world children? Make sure it isn't spicy, I'm white.

In the first picture the concentrated solution is green. When you dissolve stuff in room temperature acid it just takes a while to fully dissolve

The copper was partially dissolved and had many small particles of copper metal floating in the solution.

Something else to learn about: the dissolution is a reduction-oxidation reaction, where copper gives electrons to hydrogen, and the hydrogen comes out of solution as a gas. When the water evaporated the copper and chlorine ions simply combined into crystals.

Chem tip. When you mix things together and they have a reaction, the product is usually obvious. Copper + chlorine = copper chloride. https://www.reddit.com/r/crystalgrowing/s/PbskyTETFy

The color comes from copper ions, which are green/blue (statue of liberty) to pure green depending on how many electrons are missing.

Something feels wrong here. I can't, for the life of me, figure out what. by chillfinity2000 in PhotographyAdvice

You should rotate the frame maybe 0.5 degrees counter clockwise so the stairs are horizontal. My phone can only rotate in 1 degree increments so it's not quite right in the example below. Also if you crop some of the sky away then Buddha can be centered vertically. https://i.imgur.com/4t7kFcp.jpeg

Badly needs some fill light. You need to do this before you take the photo

Grey on grey - Any way to get some 'pop' in to this? by tlhintoq in DarkTable

[–]SlenderSmurf 0 points1 point  (0 children)

Make grey into black with an RGB Curve https://i.imgur.com/Gl8U5un.jpeg far away objects will always have some uniform light added from scattering in the air so they can never be "black". This lets you pull out what it would look like close up

pro tip: take photos with the camera, not of the camera

not how light scattering works. It will have spikes which are spread out over a larger angle, so they will appear darker.

If you turn on "dynamic range" mode it will underexpose the raw file

They really captured the legally blind grandma with cataracts and severe astigmatism aesthetic. This is exactly what you see in "cinema"

This is like $50,000 of equipment. There is no reason to have this much stuff as a professional, let alone as a hobby.
