There's something infectious about your enthusiasm, perhaps because those of us who're older hands at it still remember the buzz you get when you process your own film. Have a look now at your Electro 35, and check the seals, as your frames show some evidence of light leakage. Check the film and see if there are dark bands that cross through the sprocket holes of the film. If there are, that's a telltale sign that the light seals are leaky and need to be renewed. Fortunately, it's an easy and inexpensive job you can do yourself. If that's your problem, you'll get a truckload of advice here immediately.
