That's why I unfortunately had to take pictures at an angle.
Let me take this one sentence and build some thoughts...
1. In almost every case, scans are far superior to photos. Scanners are inexpensive and have uses far beyond philately.
2. Communication is important. It is necessary to know what we are looking at. In this case, a square-on image of the front to know what stamp it is, another of the back side which often reveals significant clues, and then any close-up images to emphasize the specific question at hand.
3. To emphasize grills, it is a rare instance where a photo is often superior to a scan. Start with a square-on image on the back, but with a very low-angle lighting from the side to cause the grill points or depressions to cast shadows. Another way (with a scan) is to adjust the contrast to a high degree to exagerrate the grill effect.
4. Angled photos are rarely of value.
5. As to value, I agree with rogdcam, collectors generally want face-free cancels which show the main design. This stamp does not have that eye-appeal from the front.
