How to add extra EXIF data when images are uploaded?

Question

I have a function to add EXIF information to an image after the image is uploaded to a website. How do I get the EXIF information to be automatically added to the image after the image is uploaded or added to the post?

I have tried some hooks like the following to check for failed photo uploads and started executing the function to add EXIF info but it doesn't work. add_attachment, wp_handle_upload and wp_handle_upload_prefilter. Whenever an image is uploaded through adding to the post, it gives an error that the image could not be uploaded.

Below is an example of my code. Every time I select an image to add to a post, I get a message like this. Please help me. Thank you very much!

An error occurred in the upload. Please try again later.

function custom_to_all_image($upload) {
    if (wp_attachment_is_image($attachment_id)) {
      //my function
    }
    return $upload;
}
add_filter( 'wp_handle_upload', 'custom', 10, 2 );

Update: Edited code to make it work

function proccess_to_all_image($file) {
    $file_path = $file['file'];
    $mime_type = $file['type'];
    $id = attachment_url_to_postid($file['url']);
    if (preg_match('/^image\/[a-z\-]+$/i', $mime_type)) {
      *//call to function here*
    }
    return $file;
}
add_filter( 'wp_handle_upload', 'proccess_to_all_image', 10, 2);
