Need advice on render settings for a specific type of photo

Helloooo 

so like I said in another post im doing a medical proyect using renders to prevent issues created when we use real patient photos.... and want to create small photos about 15x15cm with medium to good resolution but im lost with pixels and other sorts of render settings either I create a really bad quality one or end up with all night long render time... specially when I have gforce hair items in the pics (which either don't show or take 3 times longer to render :S )

 

any advice is appreciated!!!

thanks :)

    I am in doubt what sort of picture you're after.

    But a 15*15 cm in good resolution, might be a 0.1 mm resolution, meaning that your rendered image needs to be 15 cm/0.1mm equals 1500 pixel * 1500 pixel.

    Dforce hair often has a lot of geometry and will require much resources to render.

    You haven't said anything about your computer specs, here especially which GPU you have, and how much VRAM it has, as that is a limiting factor if you want to render on GPU (which is much faster than CPU).

    And why you prefer dForce hair in this.

    Why would you be interested in realistic dforce hair if it's for a medical illustration? Surely anyone needing to study images for medical purposes won't care about the hair.

    So you are printing these images?

    i want to make them look as realistic and natural as posible :) the best way would be using photos but the permits required are a head ache, also a dforce hair is easier to manipulate in case I want to show for example a scalp wound or certain dermatological problems..... also the kits I have most have dforce hair and have to work with what I have cause it's probono hahaha

    noup they are going to be posted in a website hosted by state healthcare as a education resource 

    the plan is to guide patients step by step with some text and illustrations of a normal doc visit and common problems that parents can find at home and require medical supervision ;) that way it can be free access to everyone here

    perfect, yea that's cause I'm upgrading my system, my usual alien laptop passed away :P and now I'm working on a standard notebook in wich I won't dare starting a render.... either will take a week or it will melt.... so specs will have to wait till I upgrade although I have my eye on a razor 14' biffed up and an external graphics unit ;P

    In that case a diemnsion in cm and a pixel density is not relevant, all that matters is the total pixel count. How large a screen/window do you expect people to use, that is the size you need (plus a bit to allow for flexibility/improved hardware over the prroject's lifetime).

    Well, it's the pixel dimensions that matter - and how large a screen is desired to be supported with the image full-sized.
