A Tint of Blue Reshade

First you need to download Reshade

A preset for Reshade to give Dark Souls 3 a tint of blue, plus a few other filter tweaks. Perfect for Irithyll
A Tint of Blue uses the following shaders within Reshade:

• BloomAndLensFlares [Bloom.fx]


• Curves [Curves.fx]


• Clarity [Clarity.fx]


• LumaSharpen [LumaSharpen.fx]


• MXAO [MXAO.fx]


• Tint [Sepia.fx]

Please note, the above have had their values tweaked by me in the 'Edit global preprocessor definitions' section for this preset.
