Based on the available information from a YouTube video and an article on Artfinder, here are the key steps and advice for an artist to create quick and aesthetic Instagram Reels:

1. Filming and Setup:

Shoot Vertically: Always film in a 9:16 aspect ratio, as this is the correct format for Instagram Reels.

High-Quality Footage: Use a good camera or a high-quality phone camera. Discard any blurry or pixelated takes.

Position Your Camera: Use a tripod to get a stable shot of your work.

Good Lighting: Use natural light whenever possible to showcase the colors and textures of your artwork.

Keep it Short and Snappy: Aim for 15-30 seconds to keep your audience engaged without losing their attention.

Utilize Effects: Use time-lapse to show your process from start to finish and slow-motion to highlight details or textures.

Showcase Your Space: Film with your studio or a dedicated art space as the backdrop to give your followers a look into your world.

2. Content and Ideas:

Display Your Skills: Include quick shots that highlight a specific technique or skill you use.

Tap into Trends: Pay attention to trending audio or reel formats, but only use them if they fit your artistic style.

Show the Process: A popular and effective reel idea is to show a "sketchbook flip-through" or a "how-to" video.

3. Editing and Posting:

Use Editing Apps: Use free editing apps like CapCut to trim, edit, and add effects without a watermark. This is especially useful if you plan to share the video on other platforms like TikTok.

Add Trending Music: Choose music that fits the vibe of your video. You can find trending audio directly within the Instagram editor.

Edit to the Beat: For a more polished look, try to have your video clips change in time with the music.

Check Export Settings: Make sure to export your video in the correct resolution (e.g., 1080p) to match your original camera settings for the best quality.
