>>3049778In the gig photo you have a powerful light source. What film is in the camera? Do you know what speed its shooting at? ISO 400 etc?
If your film is sat at ISO 400 and your shutter is sat around 1/80 f/8 you will always underexpose in low light situations. Disposables tend to be built for decent light with a flash built in for darker situations.
>>3049783You have a light leak - thats for sure. Plus it looks like you have a very poor light source. Again - at iso 400, without flash, youre not going to get much detail.
