Given the excellence of its batch tools and smart filter layers (amongst other things), Serif PhotoPlus X2 really is great image-editing software.
Serif PhotoPlus X2's batch tools have received less hype but, in many respects, are one of PhotoPlus's most resounding successes. Allowing you to set one of 200 different macros (changing the resolution or adjusting the colour saturation, for instance), or to record your own set of functions, these can perform a variety of different tasks in very little time. As a way of applying the same tools to multiple files, they're excellent.
Considering the excellent set of features, Serif PhotoPlus X2 remains very good value for money at £60. In a few places it isn't as professional as Photoshop, but it does cost considerably less, and given the excellence of the batch tools and smart filter layers (amongst other things), Serif PhotoPlus X2 really is a great deal.
