Jabarkan Visual dan suara dari Raiders of the Lost Ark

Lukisan matte digunakan untuk menciptakan latar belakang yang lebih rumit. Penggunaan lukisan matte di antaranya pengambilan gambar pembuatan bar Nepal Marion dan gudang tempat Tabut Perjanjjian kemudian disimpan. Lukisan matte di adegan terakhir dilukis oleh Michael Pangrazio. Spielberg tidak menyukai lukisan pesawat China Clipper (oleh Alan Maley) karena menurutnya lukisan tersebut tidak terlihat nyata terhadap air yang telah mereka rekam. Jones's attire—a leather jacket and khaki pants—was based on Humphrey Bogart's in The Treasure of the Sierra Madre (1948) and Charlton Heston in Secret of the Incas (1954). Costume designer Deborah Nadoolman Landis dumped boxes of hats on the floor for Ford to try on. After picking the right style, she purchased an Australian model she aged with Fuller's earth and mineral oil, and then scrunched beneath a bed. The hat allowed them to create a recognizable image even in silhouette. Designer Ralph McQuarrie was responsible for the Ark decorations.

Steven menginginkan gaya pencahayaan film noir yang lebih lembut seperti The Informer (1935). Sebaliknya, Slocombe ingin membuat segalanya lebih cerah dan menggunakan cahaya latar untuk menciptakan kedalaman bidang yang lebih besar; Steven lebih menyukai gayanya. Slocombe sering menggunakan cahaya alami, menggunakan perkiraan posisi matahari untuk merencanakan tata letak adegan. Spielberg liked the beams of sunlight glimpsed through scenery and tasked special effects artist Kit West with using a smoke machine to create artificial sunlight shards. For the bar fight, Spielberg wanted pitch-black shadows on the wall, but the lighting required to achieve this would have shrouded the actors' eyes; he settled for subtler shadings. He also wanted to illuminate the Well of Souls with a lighting effect through the ceiling opening, but once this was sealed it no longer made sense. The flaming torches used in the scene did not provide enough light, so he opted to use an artificial light source. Spielberg noted Allen always looked beautiful in her scenes because Slocombe would spend twice as long setting up her lighting as he would Ford's.

Pengawas efek suara Ben Burtt berkontribusi banyak dalam merekam suara film itu. The snake slithering is a mix of Burtt running his hands through cheese casserole and wet sponges being dragged across grip tape; the rolling boulder is a Honda Civic driving down a gravel hill; and the Ark lid opening is the sound of a toilet cistern being opened. The Ark spirits are the cries of sea lions and dolphins filtered through a vocoder. Jones's revolver is the sound of a Winchester rifle firing, while his whip-crack was made by recording Ford using the whip.
