Flash – iPhone, keyboard and audio output

I have a question about Dual Lightning Port and data transfer.

I am now using a camera module to connect the iPhone and the portable keyboard that sends the midi signal to GarageBand. Thanks to Apple's policy of having only one connector for the product and the high latency of Bluetooth headphones, I can use the keyboard properly (via the camera module with female USB connector for keyboard and male flash connector), but audio output is not included !

I've only tried one product so far, to be honest, and it didn't allow me to transfer data, just power and audio, so I couldn't connect both the keyboard and my EarPods.

There is a promising option to use an external audio interface, which is connected via a USB cable connected to the USB hub. But is there also a promising dual lightning port that ensures both the data transmission of the MIDI signal and the audio output?

Why do my pictures get darker when using an external flash 😓?

The Canon EOS Rebel SL3 / 250D does not have an ISO-compliant hot shoe. The central pin is missing, which is needed to trigger "only manual" flashes. Canon has recently started to do this with its entry-level cameras in the lower price range.

The Yongnuo YN565EX III is Canon E-TTL capable. However, it may not be able to cope with a Canon camera that lacks the center pin on the hot shoe. Many third-party E-TTL-enabled flashes and triggers require a firmware update to work with Rebel SL3 / 250D, Rebel T7 / 1500D / 2000D and Rebel T100 / 300D / 4000D.

Flash – What is faster for flashes, radio triggers or optical triggers?

Your question is What is FASTER, radio or optical?;; The answer is that the trigger is more important than the mechanism. Radio waves and light are essentially the same and therefore move at the same speed.

Radio triggers involve more circuitry and processing because they often accept multiple channels, etc. PocketWizard states that its MultiMax trigger response time is only 1/3000 second due to its "ultra-fast microprocessors". It was hard for me to find solid data on the response time of a typical "stupid" optical slave (like a wine), but I saw comments on it in the range of 0.1 seconds to just 1-2 ms. Despite the additional electronics, the radio option seems to be faster, but this certainly depends a lot on what type of photodiode / resistor is used in the trigger.

Still, none of this is likely to matter unless you try to capture something that happens incredibly quickly and without warning.

Typically, in high-speed photo applications, you trigger a flash pulse based on a specific event. often either sound or light beam interruption. Given that, you should be able to compensate for the 0.3 ms delay of a PocketWizard simply by subtracting that time from your trigger … that would be a matter of dialing in if you are using something special or if you use & # 39; If you are using a light / acoustic system, just move the trigger a little closer to your subject.

For example, if you fire a flash based on the sound of a balloon popping, the flash will fire earlier if you move the microphone closer to the balloon because the sound is less distant. Since the sound is slow (relative to the light), you wouldn't have to move it very far to compensate for a 1 / 3000th of a second … maybe a few centimeters?

The second part of your question Will it have a noticeable impact on photos?… most likely not since then It is not the response time of the trigger that makes the picture rather It is the duration of the flash self.

Update camera (BIOS / firmware flash) with functions of the newer camera?

To some extent, you are right with some options that depend on the software. As an example, I can give you 77D and 70D. First, you can assume that this is a new model with the option to set the maximum automatic ISO sensitivity but not the minimum shutter speed as is possible with the old model (if the automatic ISO sensitivity is activated). (Comments on this answer)

But some things depend on the hardware and that is not only the sensor, but also the processor, the heat balance, the focusing system, etc.

I'm afraid your attempt to install Canon firmware from another model (even if it succeeds) will damage the camera.

But you can try Magic Lantern. When downloading this software, pay attention to the firmware level that your camera must have. Here is firmware for 500D

The good thing about ML is that you don't touch the original firmware, you can run this software from the SD card and you can easily switch to the standard firmware by removing the card and restarting the camera.

macbook pro – Can I replace an MBP 2012 SSD with the flash memory of an MBP 2013?

Out of the box, you cannot be defined. The 2013 MacBook Pro laptops use a proprietary PCIe interface, while the 2012 used a SATA III interface.

There can It's a PCIe to SATA adapter, but I've seen everyone compatible with the Mac's proprietary interface. Nevertheless, SATA SSDs are currently very inexpensive. It is therefore not practical to achieve this additional level of complexity by adding an adapter to the mix.
