Tips for Better Photos
1. Get close: phone cameras have a small sensor and a wide depth of field. This means you can get close and still get the entire object in focus. Try to fill the frame.
2. Avoid digital zoom: smartphone cameras use digital zoom, the camera is extrapolating. Basically it's just guessing and the result is usually blurry. If you need to zoom in, try to get closer. If you can't, crop the image later on.
3. Turn off the flash: smartphone cameras use a glorified LED flashlight for the flash. The color temperature looks bad and takes too long producing arbitrary color and a blurry image. Review the lighting tutorials and control the lighting yourself.
4. Clean your lens: your smartphone goes everywhere with you and gets dirty. The grime on the lens will make your images look like someone sneezed on them. Wipe it with a clean cloth.
5. Be careful with the lighting: watch out for lens flare and hot spots. Tiny lenses are more prone to strange light effects that full size cameras. Bright reflections and hot spots can cause the camera to under expose the shot or blow out the highlights.
6. Set your phone to its highest picture quality and resolution.
7. Turn on the stable shot setting if your camera has it. Hold the camera steady: use both hands, get your feet steady under you and pull your arms into your chest or stomach. Or use a tripod.
8. Fix your exposure: smartphone cameras are slower and struggle more with low light. Setting the exposure higher will get more light into the lens.
