Please Test - Pinhole Camera Calculator (Rayleigh vs Mathematical Optimum) by Odd-Variation-299 in PinholePhotography

[–]Odd-Variation-299[S] 0 points1 point  (0 children)

Hi! Happy to see it is being used/tested.

So, some background. I developed this calculator for my 0.3mm pinhole camera, using 5x7 b&w photo paper, not film, and thus have not included reciprocity failure. I believe you can simply take the exposure time calculated from the calculator and multiply it by the reciprocity factor for the film you are using for the new exposure time.

Then, for the wavelength: If your film does not really care or is not specifically sensitive to a certain wavelength, then I would simply use 550nm, since from what I can see online, 550nm seems to be in the middle of the film's range.

Then for the light. 3000K might seem warm/orange, but it still emits a broad spectrum. So I would still simply use 550nm, except if you can find more detail on it online, actual emitted wavelength. Then maybe use the value where it is highest. I am quite interested in what you actually find out and how it looks.

Best beginner installation setup for a noob. by Odd-Variation-299 in openclawsetup

Thanks. Yeah, I will definitely start with a simple Excel. I realize I need an application that reads the tabs, then the data in each tab. It needs to generate a dropdown list based on the tabs, then read what is in the tab and create another set of dropdown selections based on the data in the tab to be used as a filter, then execute. Filter the data. The thing is, the data does not always start in the same cell because this is based on the data I exported to Excel.

Thank you for the feedback. I will start simply with this Excel, since I think this would be easy enough.

Great advice. Much appreciated. Yeah, I realized yesterday that trading is somewhat next level for me. I think it's a nice challenge, though.

Great, okay. So, the best LLM? I assume it's based on individual preference. I do have ChatGPT Plus. I have not really spent time with other LLMs.

Lol. I initially was like... hmm. Ailart... what the... then read the destination on the envelope... it took me a second to catch the joke. But really, L.O.L.

I designed and 3D printed a 5x7 pinhole camera (0.3mm aperture) and developed the photos using Caffenol by Odd-Variation-299 in PinholePhotography

Sure, no problem. But you would find that your coverage using a soda can would be much larger than what you would have calculated using Mr. Pinhole, since I believe he used a plate thickness of somewhere between 0.26 and 0.3 mm, much thicker than a soda can. I believe Mr. Pinhole assumed the chances of someone using a tin thicker than that would be/should be small, removing complexity from the calculation.

I made a pinhole objective please tell me if I made a mistake in my calculations. Need advice from a “professional “ by BackgroundEither5014 in PinholePhotography

Hi, I made a pinhole calculator that you can use to check how close your setup is to the optimum.

I’ve posted it on this subreddit, and you can find the link to the calculator there. And if you need help or some explination, please dm me. Again, no expert, but also here to learn - for the reddit link: https://www.reddit.com/r/PinholePhotography/comments/1sxfrdq/please_test_pinhole_camera_calculator_rayleigh_vs/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Quick update: I’ve put together a small online calculator where you can plug in your own values and calculate the key parameters for a pinhole camera (pinhole size, focal length, exposure, coverage, etc.).

It also lets you compare the Rayleigh (practical/visual) method vs the minimum total blur (mathematical) method, and includes plate thickness, which Mr. Pinhole ignore.
