Need a bit of help with up scaling. Up until now I’ve been upscaling the finished poster and not the image I’ve created on midjourney (apart from the upscale on the app). I’ve received an a2 order. I’ve upscaled the image separately to upload to canva but it says the image is larger than 50mb so I can’t. What should I do? Will it be ok to upload the exported poster as I was doing before as long as it meets the pts recommendation?
