We love being on the sunny side as much as the next guy, but with Color Shade film being super sensitive to light after exposure, pictures have to get shielded from light IMMEDIATELY as they get ejected from the camera - the first few seconds are crucial!! There are several tricks how to shield the image from light upon its ejection from the camera. You can either cover it with your hand, a darkslide or your shoot directly into a box.
Insufficient shielding will typically result in very light, low contrast images. With the PX 70 PUSH and PX 680 film, poor shielding will also result in a strong pink or orange haze over the picture.
