render e parametri

[blubossa]

I have to make a render of an electric qaudretto, in short plastic stuff, it is I find myself struggling with the attempt to set the parameters to get a decent tiff.

doing a search on the forum I noticed that many of us fail to have good results, while someone else is + that satisfied especially with the w5 that uses as more mentalray.

apart from asking for directions to make the above indicated, I think that by collecting the various parameters that each one of us has used, obtaining good results, these could act as a ref. for others to make so as to have a starting base.

Thank you.

I'm doing a lot of evidence to better understand the renders............problem...

If I want a render of what I see on video with a resolution of 300 dpi as I do...........I have tried in various ways and only exports me to 72 dpi!

I hope someone listens to me... and give me a tip.

However pro-e proposes me a 100 dpi rescue of the render, instead I want to set the option to 300 dpi, I think in some configuration file you have to go to put hand, but I can't find it......atendo.

Thank you.

in any case you have to pass from photoshop and from you add everything.

I know perfectly that I have to pass from photoshop, the problem is in output, allows me to export the rendering image or to 72 dpi or to 100 dpi.

then going to resamp the image in photoshop, at 300dpi, the size of the actual image is greatly reduced to a base of about 7 cm and for me it is too small.

I hope that it is possible to set the dpi and size of the image in otput...either tiff or jpg

dpi serve in print, what you need now is an image with a decent resolution. in rendering settings, after selecting "rendering a tiff", put a custom image size e.g. 4800x3600, after you can import it into photoshop having the detail that interests you.. .

in photoshop you can also oversamp. parts from an a4 72dpi and you can make it an a4 300dpi.
It is understood that the information where there is no can be created, so the result is not like launching a higher resolution rendering, however the expansion algorithms of photoshop allow to obtain oversamplings with decent results.

I know the sampling but it reduces the format, how do you do an oversampling?

Thank you.

ok I try.....but it seems to me that it did not give me the possibility of customization of the format

mine was an engraved one. Just use it if you can't do anything else.
in photoshop, open image properties and unlock resamping (bottom in the window, I don't remember exactly what the word is). see that after you can change the dpi and mm independently.

Okay, I know this technique, but it doesn't solve the problem... .
in practice if you go to resamp the image by increasing the dpi obviously reduces the base and height of the image, and vice versa......... does not solve

rendering software usually cares about dpi, export to 72 or 100 because those are the dpi of a monitor (perhaps windows 72 and mac 100, but I could say a stool).

apart from the colossal baggianata to define the dpi of a monitor (depending on the resolution and size of the monitor of course), I would say that what you need is a large "low" image to be good in print, then change the size in pixels accordingly. for prints on a4 sheet at full page I think a 3000x2000 can suffice.
increasing the resolution in renderings is never free, so sometimes it is better to use a lower resolution and then scale the image. I suggest you try also "smilla enlargementr" a free software that enlarges images adding effects that make them look less "enlarged" :d

I probably didn't explain well.
unlocking the resamping, increasing the dpi does not reduce the base and height of the image.
missing information is compensated by adding intermediate pixels whose color is calculated based on well-made algorithms.
