Tiffen Dfx 4 Photo Plug-in
$150 (around £123) http://software.tiffen.com
At its heart, Dfx 4 digitally replicates many of Tiffen’s own glass filters and gels, but dig deeper and you’ll find a huge range of colour and mono film stock emulations, plus many more generic filters. Each can be adjusted to varying degrees, but those with more extensive customisation options require you to negotiate a long list of tightly packed sliders to adjust techy parameters such as gamma and saturation across each colour channel: no light leaks or grain options here.
Elsewhere, some cryptic navigation and view icons further steepen the learning curve. In fact, the interface as a whole could do with an overhaul.
But underneath all this is a fast, powerful plug-in with plenty of potential. You get layers and blend modes, plus masking tools for localised targeting of effects. A batch-processing feature seals the deal.
Tiffen Dfx 4 works on Macs and PCs and is compatible with Lightroom 3 or later. It requires a dual-core processor and 4GB RAM and supports JPEG, TIFF and RAW files.
Packed with presets; selective editing and effect stacking; snappy loading Cons
Limited preset adjustment; cryptic icons; somewhat awkward interface We say A capable option, but not as polished as some rivals Overall score
Dfx enables you to add effects to separate layers, while the EZ Mask tool makes light work of masking
