If you try to shoot a panorama without a tripod, you’re likely to encounter a variety of complications when you try to stitch them together, a topic also covered in Chapter 8. Use a reflector, polarizer, or split neutral-density filter when appropriate. Even though it’s essentially possible to create a custom neutral-density filter digitally in Adobe Camera Raw or by using adjustment layers and
within them. That may make it seem that you would be wise to underexpose rather than overexpose, but the fact is that more noise may become visible in the image when it is lightened, as shown in Figure 1.5. For the best results, try to limit lightening in a raw converter to one stop or less. We’ll talk more about this issue later in this chapter when we discuss exposing to the right.
