Noise is where you increase the ISO (needs more light sensitivity when little is around). Sun flares are not always bad, they can enhance an image rather than be detrimental. The best noise software I use is Topaz, but I do have the Franz german ones too. You can download PS on your tablet or phone. I think that that is a free app? Need to check on that one. But serious editing, I have to say It's either a laptop, or desktop. I love desktop as it is cheaper than buying a top end laptop and its a larger screen.Yeah sadly I do all my post editing on my phone and I'm nowhere near professional at yet but I will invest in a laptop soon to help
I've also purchased some lens filters to help with quality in the sun
Any other tips to reduce noise?
