In Affin­ity Photo, lay­ers can change how an im­age looks by build­ing on top of it with­out af­fect­ing the orig­i­nal data. has gained a new layer called ‘(Black & White Ad­just­ment)’. Clear the check mark to its right and the ad­just­ment will be dis­abled. You can cre­ate mul­ti­ple ad­just­ment lay­ers and ei­ther blend them for new ef­fects, or make dif­fer­ent treat­ments for the im­age within one file.

Next, add some grain. We’ll use a live fil­ter layer to cre­ate a layer of grain that can be in­fin­itely ad­justed. Pick Layer > New Live Fil­ter Layer > Add Noise Fil­ter. To keep things pho­to­genic, en­sure gauss­ian noise, rather than uni­form, is se­lected. This looks at the bright­ness val­ues in your im­age and adds noise in sym­pa­thy with them, while uni­form sim­ply adds ran­dom speck­les. Also en­sure the ‘Monochro­matic’ box is checked.

Less noise is more. If you’re view­ing the whole im­age and add noise un­til you can see it, you run the risk of adding more than you need. In­stead, zoom in to at least 50% and add enough noise that the sharpest edges are just slightly blunted. You’re aim­ing to soften your im­age ever so slightly and add a hint of tex­ture, not ob­scure fine de­tail en­tirely.

Once you’re happy with the look, close the Live Add Noise win­dow. You’ll see your im­age now has three fil­ters. Dou­ble-click the Add Noise layer’s icon if you want to amend things.

When you’re fin­ished, re­mem­ber that File > Save As doesn’t let you change the file type. In­stead, pick File > Ex­port, which of­fers a panoply of for­mats.
