What's wrong with those shots?

[WalterMelonPomelo]

Hello Everybody,
I've just got digital scans photos from my last trip.
A few of the shots seems to be invisible.
What's wrong with them?
I wouldn't; make the same mistakes in the future.

I don't think so the film was expired because some of the photos from that are ok.

Is there any idea of digital processing to rescue this photo?

What happened here? Next exposure from the same film turned out good.

Is there a problem with the camera, film or scan?

The one with the birds looks like a camera light leak.
I don't know about the one with the people because you didn't say what you feel is wrong with it.
For the two more-or-less blank frames you need to say what is supposed to be there. For all we know they are perfect photos of the inside of your camera bag.

1. Close up of a water melon? or no exposure
2. The undead? Hard to capture on film. Or underexposed.
3.A lemon coloured back lit sign and a gathering of people who talk with thier hands, or either the scanner missed the frame or it is the first or last exposure on the roll of film.
4. A solar wave. or a light leak. If on the beginning or end of the roll, most likely caused by the canister leak normal for a camera, best to after you load your film to close the back and fire off three exposures or till the camera comes to 1. If mid way through the film roll than it probably the camera leaking light.
