I want my animation when rendered to look like this for example
but when the animation is rendered it looks like this
Is there a way I can do this? Any help is appreciated!
There are 2 ways to make your object brighter, you can change the scene settings (lights and world color + strength):
Or you can plug your image into the Emission input of your Principled BSDF and even play a bit with the Emission Strength, as the object emits light its texture will much less depend on the scene settings:
You could even mix a Diffuse with an Emission, which may give you more control:
If you want to avoid any shadow and only need Emission, then directly plug the image into an Emission node:
