I know DXO has analyzed a lot films and you can add film grain with DXO software, but is there other software for adding good film grain ???

Does photoshop have this functionaliy with multiple sorts of film grain ?

Or are there somewhere offered "Film grain" files to mix into the images by using and easy combination ( multiply, negative multiply.. ) ?

You can selectively add Gaussian noise to a image using luminance and shadow masks. You can create these using the Claw Method of selection...

Make duplicate layers and increase/decrease layer size to get different grain sizes.
 
--thanks. your link also is not too expensive.

I will feature-compare this with dxo filmpack and post the result here.

whats good at your software: adding grain depending on image size, because i think it makes no sense to add grain to a 7MP original intended for poster prints, then resize the file and print 4x6" - because the grain will get so small that no one sees it.

perhaps someone has a remark about resizing files where film grain is included - is this at least sometimes useful or is it better to always add the grain after resizing
 
The best method that I have seen for applying realistic film grain to a (black and white) image (in Photoshop) -- is to add a filmgrain image layer on top of your photo - and change the blending mode to overlay. There are dozens of on-line tutorials for using this image: http://byscuits.com/ grain-tm400.png ( it's too large for me to link into this thread - just remove the space, or click on the link and add "grain-tm400.png" behind byscuits.com/ once you are there).

1 - Download the png file -- I converted it to a jpg (which was easier for me to work with)

2 - Convert your image to black and white using whatever method gived you best results (I use a B&W adjustment layer in CS3 now)
3 - Open the grain-tm400 image above - and drag it into a layer over your image

4 - Change the blending mode to overlay
Too strong? Apply a slight gausian blur to taste . . .

This is a method takes a second (far longer than it took to type this). Apologies to whoever in the world created the original tutorial ( it was a couple of years ago I started using this method).

Marf,

RealGrain is one of the plugins I test for. I'll give you some insight on 'grain adders' that may help you out.

First off, there is realistically no 100% accurate method of adding grain to a digital image. The grain of film prints is a combo of the film characteristics and development process plus the paper used. Wet process paper texture and type have a big bearing on the portrayal of the grain.

RealGrain has the ability to do a very good simulation of most any type of wet process within these limitations. It also gives you the ability to create your own grain characteristics that is unique to your needs. Most people don't realize that a lot of the grain look of wet prints isn't just a canned process. Some wet printers used and still use techniques of their own that give that unique look.

Plus, RealGrain gives you the unique option of tailoring your grain look to the tonalities of the image as well as combining tones and applying this grain to specific color ranges and luminosities. Put all of this together, and you have a very good simulator that can generate grain simulations that are limited only by your imagination.
Regards,
VG

Hi Marf,

I'll be honest: if I want grain I'll use film. I am using digital and I have no inhibitions in admitting that. I do appreciate that adding grain has sometimes a particular charm, but IMHO I think I should exploit the possibilities of the medium I am working with. Nevertheless, good luck in finding the right plugin.
 
I am sure I will use it for some of my images, but I will also test some software above mentioned

I have three grain generators in my B&W action that are separate actions from the B&W conversion. The three actions are designed to work with different versions of Photoshop and the latest uses the 'grain' texture in CS2, then 'film grain' in CS and noise in PS7. The grain in all cases is applied with the characteristics of film grain - iow, there is more grain in the darker luminances, less in the mids and very little in the highlights, although you can adjust the opacity on each of these luminances. A fade in luminosity to get rid of the hue/color shift is after each filter, so you get the 'good' gray grain, although if you want the color you can uncheck those steps. Intended for B&W but you could run them separately on any image.

I come back to my previous posting: we used to avoid grain at any price. Asking now to add grain to a picture is for me the equivalent to noise up a digital picture. I think it is a waste

1. Its an effect like B&W conversion and blurring - I am currently sitting in front of my image processing program and can see every detail of the skin, good or bad - but the customer does not want that that everyone who sees the picture sees maximum information - so we blur PARTS of the image or remove information in another way. This is also done by adding grain

2. Its adding something else to the image which was extracted from the non-digital age

And: Who used to avoid grain at any price ? Not I, it may be a dpreview review paranoya. My opinion: Color noise looks bad, Monochrom noise can sometimes look good.

I tested this 2 years ago, maybe I will think about it again, but i think it does not do all I want.
