CORRECT FILTER CASTS

Use software to neutralise colour shifts introduced by high-density filters

1

TEMPERATURE AND TINT To further customise the colour balance and make the filter effect more chromatically invisible, use the Temperature and Tint sliders to make more precise global adjustments. Avoid large slider movements to prevent introducing other unwanted colour shifts.

2

SET BLACK/WHITE POINTS Before we start making any colour corrections, it is advisable to set the overall contrast for the shot, as this can change the apparent dominance of the colours – setting this first saves time. Move the sliders until just before highlight and shadow clipping occurs.

CORRECT GLOBAL CASTS Use the White Balance Selector Tool in Lightroom, or similar editing software, to quickly remove any strong, image-wide colour biases. With the tool active, click on an area close in tone to neutral grey to instantly centre the colour. Click in multiple areas until happy.

CURVES CONTROL For even more precise re-toning, use the Curves tool in your software package to make adjustments to each channel independently. Here, we made changes to each of the Red, Green and Blue channels to both neutralise and exaggerate certain colours, for a more bespoke look.

HSL ADJUSTMENTS As a final, optional step use the HueSaturation-Luminance control to adjust the apparent brightness of different coloured areas, alongside the hue and intensity. Experiment with different combinations to see if the filter has impacted local areas in different ways.
