A graphics tablet is really a must for any photographer who works in applications such as Photoshop, Lightroom, Aperture and Co.. The precision and accuracy that can be achieved with a tray, will never be implemented with a mouse. Only the Druckempflindlichkeit of pins contributes to enormous relief work. Thus, masks and Co are drawn exactly and depending on the pressure increases the opacity or not. Thus, the annoying change of Druckempflichndlichkeitsregler falls like opacity and so away and speeds up work processes. Another advantage over mouse is that you (can be changed) absolute positions, which means that the upper left corner of the tablet entsprecht also the upper left corner of the screen - so you can quickly jump from one position to another.
In addition, it has in a number of Wacom with Touch Control buttons can be assigned to quick functions. In addition, there are small displays, which can be labeled on PC / Mac and the application may be different - so you can always see what now has the button just for a function. In addition, there are still different at Wacom pen tips that change again the softness and reaction of the pin. So you can select top that suits the operation. Also the pin has 2 more keys, for example, can be freely assigned with the right mouse button.
The size L is ideal for working with two screens (with me 24 ") and lends itself to very optimal. For mobile use, I would recommend the M in Wireless.
