This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
This filter adjusts basic photo parameters such as RGB levels, Luminostiy, Saturation, and Tint blends. That is, it's for color and luminosity adjustments.
One theme here is that for each area to adjust there are two contollers – the "Hi" ones adjust the lighter parts of the channels, while the "Lo" ones adjust the darker parts. (E.g. Generally, higher "Hi" values with lower "Lo" values will increase the contrasts, while inverting this idea often decreases the contrasts...)
Notes:
– You can set Saturation to 0 to explore Black and White fx with the RGB controllers.
– For more of a Lomo effect experiment with increasing the reds and greens and/or decreasing the blues.
– If you're not sure what style/direction you want to go, click on the "Next Variant" option for random explorations. (That's what I did to create the presets.)
– Preset #10 has a default setting for a neutralized starting point (where there is no fx).
– Each image is different - so experiment a bit.
