I wanted to save some money not to buy holders and GNDs and create digital filters. Thus far, I've been using soft grad for both Photoshop and Lightroom. However, I could not simulate Hard Grad in either software. A search in google points me to the hardware GND instead of how to do it in photoshop.
My guess is that doing this is the same way as creating soft grad filters but with some settings to tweak to create hard grad with soft grad line.
Could anyone shed some light or point a direction where should I look?
