Tips and tricks - So how exactly do you make a film with a smartphone? Here are some tips.

The right fit - Firstly make sure using a phone is actually right for your film. Shooting with a phone isn't just good for budgeting reasons, it can enhance the atmosphere of a film.

Cinematographers - When shooting with a smartphone, your cast may double up as cinematographers. That's right, an intimate production may mean cast will film their own shots, or help the director as a videographer.

Additional apps - Smartphones have some pretty high-tech cameras, but you may need to use some other tools. Apps like DJI Osmo Mobile and Filmic Pro have been used by professionals in order to enhance certain shots and lighting.

Manage your expectations - Shooting with a smartphone has many benefits for a filmmaker. View it as a tool, providing a certain look on a budget. However, the lighting, colors, and exposure will never be as good as an expensive film camera, so have reasonable expectations.

Embrace the imperfections - The imperfections of phone footage can be very effective. They can give a raw, human look to an amateur film.

Stay charged - Another limitation of shooting with a phone is its battery limitations. Make sure to pack plenty of battery packs for shoots, and try and get a generator if you're shooting remotely.

The whole production - Smartphones aren't just used for shooting. You can also use mobile apps to edit, produce, and soundtrack a film you're making.

Try using a tripod - Most smartphones have built-in image stabilisation, but professionals recommend using a tripod to get a strong, stable shot.

Get close - Most smartphones don't have an optical zoom, and actually just digitally enlarge the picture. It's recommended that you just get closer to the subject, to avoid pixelation.

Close to the subject - Smartphones don't have the best microphones, so try to get as close as possible to your subject. Also look at using an external mic to get the best possible audio.
