Always remember that external shade is just part of the equation. Just like cooking meat, it's important to know what's going on inside. Sometimes it's difficult to take photos of roasted coffee as the light, lens and camera settings can distort the result. Suggest getting some form of shade scale (just like a color sample) that you can place next to the beans when taking the photo so it can offer a degree of comparative reference. If the beans are too light and if by chance under-developed (which is not known at this stage) it may provide some challenges in espresso extraction. Letting them rest even longer may help, so too can using them for non-espresso brewing.
