daz is pretty much drag and drop when it comes to placing your assets in the scene. thats about it. with a few clicks you can have a descent setup.
you can find plenty free assets online, and I mean free not pirated. from characters to clothes and enviroments. daz store has freebies too plus it often has fastgrabs of up to 70% price cut. you can get a high quality asset for as low as 3 dollars.
you will sooner or later need to invest some money, mainly in clothes, hair and shoes since those are dificult to create. the basic morphs that come for free with daz offer you the basic tools to make your own custom characters. not to mention that you get all basic genesis characters of up to gen9 for free including some basic cloth, skins, hair and poses.
here is where the easy part stops
making a realistic looking character requires skill, creating the right lighting takes knowledge of photography, lences, camera angles, focal lengths, depth of field etc because just slapping spotlights only burdens your scene and it looks bad most of the time. then there is dforce where you want to invest some learning time if you want the clothes to sit on the model and not look bad, and finaly you ned to find the details for the render settings., the denoiser etc.
if you go for manual posing you will need referecnes to move the figure and make it look descent.
but honestly youtube is full of tutorials. rauko is a great youtuber who goes into details from beginner to more advanced stuff.
my very first render is this one.
