: Modify exposure parameters such as shutter speed, aperture, ISO, and white balance. Remote Shooting
One of the most confusing aspects for newcomers is the event handling mechanism. The SDK uses either (set via EdsSetObjectEventHandler and EdsSetPropertyEventHandler ) or manual polling (with EdsGetEvent ). The official documentation describes the callbacks but doesn't emphasize that you must run a message loop or wait on an event object, otherwise no events will fire. This is where the sample code saves you.
Note: The actual byte values representing exposure parameters (Tv/Av/ISO) use Canon's internal hexadecimal mapping scheme, which is documented in the appendix of the API Reference Guide. Step 3: Triggering a Remote Capture
When your implementation fails, the EDSDK returns a specific 32-bit hex error code. The definitions can be verified inside EDSDKErrors.h . Success. canon edsdk documentation
Study the sample code liveview_sample.c from community repos. You’ll see that you need to:

Without the EDSDK, building a tethering application for Canon cameras would require reverse-engineering proprietary protocols—a near-impossible task. : Modify exposure parameters such as shutter speed,
