Newbie here. Just got my first roll of Fuji 100 color print and many seem over exposed.
Since I cannot change shutter speed, what can I do?
Have a daylight 1A filter.
Thank you so much...

I created a page about testing a Yashica Electro (including the GSN). Give those tests a try.

Given your results, I suggest one more test... I have had an Electro that gave correct shutter speeds at some f-stops but not at others. This is quite possible, given the electrical design of the camera. You want to see if the shutter speed changes by half as you shift f-stops. Without film, in medium indoor light, close the aperture until the yellow light comes on. Click the shutter. Close one more stop. Click. One more stop. Click. For each change in stop, the shutter should stay open twice as long.

Repeat in dimmer light so the yellow light comes on at a wider stop (lower f number).

I had an Electro that was perfect at all stops except f/16 at which the shutter stayed open way too long.
 
Not familiar with the camera, but if you're in broad daylight, and set the aperture to (say) f/2, then the fastest shutter speed of 1/500 will not be enough to stop the film being over exposed by a fair margin.

The key might be to simply stop down to f/8 or something, in bright light.
 
The ISO marker plate (underneath the dial) on my GSN was loose when I got it and would spin out of position at times. I recommend checking for this by rotating the iso selector ring all the way in one direction and make sure it aligns the indicated min or max iso. If not you will need to figure a way to adjust the underlying plate so it is correct.
 
While we are at it: Overexposure... All frames? If not, then that may point you to the cause. I think all the comments above are on target.
 
Might well be the "shooter" instead of the camera. I will be more diligent until I figure out what is happening.
Thanks to all
 
Dennis, did you reach the conclusion that they are overexposed because....?

1) you looked at the negs directly, and they looked overexposed; negs looked dark.
2) you scanned the negs, and the images yielded from your scanner looked overexposed.
3) you looked at the prints that you received from the lab, and they looked overexposed.

What looked overexposed can turn out to be properly exposed or underexposed in many cases.
 
Actually, all I have looked at is the cd done by the film store. Not all are overexposed, but most have a hot spot.
Very well might be my not using the over and under lights correctly.
New film in camera. I will start using tomorrow but with more attention paid to lights.

Thank you for your suggestions.
 
Believe me, it's not hard to lose track of what the camera is doing while the shooting gets interesting. I've done that many a time. And when using multiple cameras, it's even more important to remember to check the meter. I took four cameras on a shoot one time, but luckily my brain was in high gear that day.

The CD image having the hot spot has nothing to do with the overexposure in most cases, especially when it's shot with a ISO100 speed print film. It's more likely to be the consequence of the poor job at the lab. You can tell the shot was overexposed only after looking directly at the neg itself; and it's virtually impossible to discern it unless you are extremely experienced with it. With print films, you can yield a decent result (either CD image or print) even when you overexpose it by 4 or 5 stops.

Well, I think I have the answer.
As I said, I am a newbie, and what I thought was overexposing was, I think, light leak! Camera door not tight.

After reading so many times about "change the seals" I finally checked mine; not just poor condition, actually missing in parts of the body.

So, thanks to Jon Goodman, I will replace seals this weekend....
Feel really stupid on this one.......
 
Hey, you're learning, Dennis, and that's the important thing. There are many more things to discover as you journey along photographically.

OMG: looks like mine. Thank you so much. I am now more certain than ever leaks is/are my problem with my beautiful GSN.
My GT door is very tight, but will be looking at it very shortly.
Thanks again,
Dennis

Dennis, the GSN light leak I had required that I put a little bit of light-blocking material on both sides of the door hinge.

The key test is to shoot four frames or run through four unexposed frames, so you are ready to shoot frame 5. Then leave the camera in bright light for quite a while. Finish the roll. Check for light leaks showing up on frames 3 and 4.
