Anyone knows how this poster was designed and if possible to reference some tutorials for the same design or close to it?
They probably created shape layers, added glow/inner glow fxs, maybe a light faded bevel. Colorized those. Looks like two instances of a lens flare with a blend if layer adjustment. Slapped some text on top and called it a day.
Not being funny but there’s tonnes of online tutorials.
Look up glass effect photoshop, glass effect illustrator.
Also search for neon glows etc.
You could even technically do that design in InDesign - it has similar effect features a Illustrator and Photoshop.
Personally - I’d try to keep it vector as much as possible - so Illustrator would be my preferred.
