It would be great to be able to apply some filter to the default media title to avoid a lot of painful job after upload.
For exemple remove the added - when filename was created, capitalize first letter, trim, remove pic prefix number, ...
May be just a plugin hook
It will be great to be able to add it to the excerpt field also.
I did my personal hack in wp-admin/includes/media.php->media_handle_upload
After EXIF management
// If begin with 00- remove it
$title = preg_replace('/[0-9][0-9]-/', '', $title);
// Replace - by spaces (to revert automatic file naming)
$title = preg_replace('/-/', ' ', $title);
// Capitalize first letter
$title = ucfirst($title);
Then in // Construct the attachment array
'post_excerpt' => $title,
