Nik software filters are now free https://phlearn.com/intro-nik-filters-p ... letter_nik
I already have them (paid nearly £60 a few years ago) and use them a lot. For those that aren't familiar, they are a plug-in for Photoshop and Lightroom to enhance your photos. The Sharpening one makes sharpening very easy and the Silver Efex turns your images in to Black and White. I like the Viveza one for lightening up dark shadows.
