hardware – Can I access both cameras, wide and normal at the same time?

Some smartphones have two cameras, working together as one implementing different parts of the zoom range.

Is it possible to use both of them at the same time?

With both at the same time, I do not necessarily mean reading the frames at the same time synchronously, reading both with 30 Hz from different threads would be great.

A problem could be if a camera needs to be initialized somehow, and only one can be in the active state at a time.

Connection sharing – All cameras on the market that can be controlled via USB and open API

Hello, I'm curious to know which cameras (without mirror or similar) or camcorders on the market can be controlled programmatically via any API, ideally via USB, although I would also be interested in blutooth.

Camera commands to support:

  • Opening
  • Shutter speed
  • ISO
  • Target development
  • Start / stop video recording
  • Video recording settings such as image size, aspect ratio, encoder quality, etc.

I'm not interested in webcams or IP cameras, the unit should have the ability to write to its own storage medium such as an SD card.

Organize photos with smart albums and other cameras

I am trying to organize my photos on Photos application

Here are the steps I'm following (extract from David's youtube video)

  • I create a folder
  • I create a smart album on the folder
  • This smart album has 2 rules
    • Satisfy being between two dates
    • To not be in another album "The album is not"

The problem that I have is that it seems that the photos that I took with another camera (not my iPhone), it did not appear . it's as if they already belonged to another album.

What are the minimum lighting conditions necessary for good autofocus in compact cameras (sub DSLR)?

By good autofocus, I mean stable focusing in 3 seconds or less.

By compact cameras, I mean for example the Canon SX.

And I'm interested in a measurable criterion (preferably in Lux).

Edit:

I'm not looking for a specific answer for a specific model. Just for an order of magnitude – like 100 Lux is usually enough.

canon – How to operate two cameras via OBS?

I have a Canon Rebel T6 and T6i. I am trying to set up a live stream for my local community theater, and I would love to have both setups so that I can switch between different angles. I can easily insert a camera into OBS using their beta webcam utility, but there is no support for multiple cameras. I have also tried digicamcontrol, but it worked far too slowly to be achievable. I have been trying to find information online, but have had no luck in the past 2 hours. Any help in the right direction would be greatly appreciated. I'm looking for something inexpensive and efficient. Thanks in advance

Is there a valid reason not to choose the C-RAW format in recent Canon cameras?

Canon has introduced a C-RAW compressed RAW format with its new cameras. Compressed RAW files can be processed on the computer as flexibly as with uncompressed RAW files.

Apparently, the compression ratio is around 1.75: 1. The savings in disk space are therefore enormous. In addition, the camera’s burst buffer is increased by at least 1.75x, maybe even more (effectively) as the camera will start to flush the buffer on the card immediately. and not when the tampon is full. The continuous shooting speed with full buffer will also be increased by 1.75x if the card is limited.

C-RAW will be stored in the new Canon .CR3 file format. This could suggest that C-RAW files cannot necessarily be opened by open source software. However, recent Canon cameras still use the .CR3 file format, even for uncompressed RAW files, so this counter argument may not apply.

C-RAW appears to use a lossy compression algorithm. However, Bryan Carnathan has studied its quality and lossy compression does not seem to be an issue. The differences between RAW and C-RAW shots seem to lie mainly in random noise. The dynamic range is not injured as it is with JPEG.

Because there doesn't seem to be a RAW -> C-RAW converter that you could run on a computer, selecting C-RAW (plus JPEG too if you're not shooting high speed limited by buffer) on the camera seems to be the wisest choice.

So my question is: is there any valid reason not to choose the C-RAW option on recent Canon cameras?

unit – How do I know when the cameras change?

I'm working on a script that uses raycasting from a camera perspective to see what the player is watching. Pretty standard stuff. The only question is, how do you find the camera reliably?

Everything I've seen says you don't want to use Camera.main in Update() because performance, you should rather call it once Start() and cache it in a field. And it's great, as long as you can guarantee that the main camera will never change. What if this is the case?

What I would like is to have some sort of OnCameraUpdated event that I can subscribe to that will let me know when the main camera has changed, but I don't see anything like it on the Camera class. Is there a good way to find out without questioning it?

Zoom problem for several Unity cameras !!! Android 2D

Hello how are you? I don't speak english, so i will try to use google translator to express my problem.

I am creating a 2D game for Android, for school work, in which I have 1 main camera, which concentrates the whole scene (the hub and a central image (without canvas))
The objective of the game is to find differences in the main image (it is an image split in half, with differences on both sides)
I have tried to put two cameras and properly adjust the display window, and it works for me, but the problem is that when setting the game on different screens, the window display is extremely bad.
I'm looking for you for help that you can give me, or an idea.
I tried to use a canvas for the hub, and 2 independent cameras for the image (one in the upper half and one in the lower half), I tried to ; apply dozens of tutorial codes on cameras and scale, but I haven't been successful, 5 days ago that I'm with this problem.

The only way I managed to get the zoom to work is that my image was cut off when it was scaled on other screens, this which is a problem.
Please wait for your help!
