article: Go into the settings of your camera and set it to manual mode, if it isn't in that mode already. Set your camera to your preferred ISO and aperture settings. You'll need to do some experimenting with both of these settings to find the ideal settings for the photo you're trying to get.  The ISO setting determines your camera's sensitivity to light. The higher the ISO, the more sensitivity to light. Generally, lower ISO settings produce clearer pictures while a higher ISO will cause graininess, but there are some scenarios where you'll need a higher ISO, such as when shooting a subject in motion.  The aperture setting changes the size of the lens, and therefore how much light the camera lets in. This setting is describes using the unit f/stops. A larger aperture number, like f/11, means a smaller lens size, and a smaller number, like f/1.4, means a larger lens size. Aperture affects your photos' depth of field and shutter speed. For whatever ISO your camera is set at, input that number into the allocated spot on the light meter. Do the same with the aperture that your camera is set at. Depending on what light meter you are using, you may need to twist the knob around the white dome on your light meter to prepare it. This is the sensor of the light meter. Most light meters have two modes, one for ambient light and one for flash. If you're going to be using the flash of your camera, set it to that mode, and if not, use ambient.

article:
Use a cloth lightly dampened with your chosen cleanser to wipe the stained area. Drag the dampened cloth over the area gently; you do not want to scrub the leather. Be sure to wipe the entire surface of the stained area from edge to edge, seam to seam.  It’s important to clean the entire surface, since you could leave a new stain on the leather if you just clean a specific area. It’s better to dampen and clean the entire section of the leather cushion, rather than only treat the stained area. If you want to make your own cleaning solution, mix together 1 US quart (0.95 L) of hydrogen peroxide, ¼ cup (58 g) of baking soda, and 1 tablespoon (15 mL) of liquid dish soap. Gently combine these ingredients together in a bowl. Dip your cloth into the solution and wring it out. You can also use white vinegar as a natural alternative to hydrogen peroxide. Vinegar can help disinfect and deodorize the stained surface. Since the stuffing may be saturated with urine, you need to use an enzymatic cleaner to remove the urine and dispel the urine’s potent, chemical odor. Wash the stuffing as you would wash any kind of clothing by hand, in a large sink or tub. Apply the enzymatic cleanser to the stuffing and use your hands to work the cleaning solution into the urine-saturated area. Squeeze the stuffing and rinse it with clean, running water. Do this many times to be sure you completely rinse out and neutralize the urine stain and odor. Allow the stuffing to dry naturally outside. If the stuffing can dry outside in sunlight, that may help get rid of the urine smell even more. Insert the stuffing back into the leather cushion once the stuffing and cushion are both completely dry. Do your best to reposition the stuffing how it was in the cushion originally, and zip the cushion shut again. After the leather has fully dried, apply a leather conditioner to the leather surface. Apply a small amount of conditioner to a soft rag, and use the rag to wipe the entire surface of the leather. Be sure to coat all sides of the leather cushion. A leather conditioner will ensure that your leather stays soft and supple, replenishing any of the natural oils that the cleaning solution may have removed from the surface.
