Noob question: Glowing Edges - Is is done in photoshop

[jhanphillipco]

Hello fellas. I've been using vray 1.46 advance for 2 months now and i cant seen to get the render that i wanted in my render. Here is an example work i wanted to have. I want to emphasize this thread on the glowing or blurring edges on the picture. this seems to make the render more realistic. How is this being done? is it rendered usually in vray then exported to photoshop and do the effect? thank you in advance guy. pardon some of my grammar.

 

Here is the pic...

I am assuming you are referring to the bloom effect. With Vray, it is usually handled in post. With Mental Ray, some use the glare shader.

I only have a limited acess to the internet right now. I think that's the effect that i am looking for john. I attached the jpeg and don't mind the composition and materials in th picture. my main concern here is the bloom effect. I only use vray in max8 right now. what do you mean when you said that it is done in post? isn't it done with the Antialiasing filters? Haven't tried to though. Thanks guys for your help.

 

And this is out of the topic, but im planing to use HDRI for my exterior render so that i could achieve a better glass reflection. will this eat up a lot of render time?

 

Here are some other images

Hello Kabayan!!!

 

Here's a tip,coz i usually do that in my works.I dont know how other people do it,but as for me,its in post production.(i dont do animation so i dont know how they do it directly in max)heres how i do it.

 

1.open youre image in photoshop

2.add up another layer

3.make that layer as "overlay" instead od normal.you can find it just on top of the layer pallete.

4.start using the airbrush tool using a white color with a low opacity on desired area so you can control the whitish part from blowing all over youre scene.

 

thats it.i hope it would be of some help.

Another similar method:

1) Copy certain parts of the image that you want that effect on to another layer above the image, making sure it is in the same location (Photoshop)

2) Add a gaussian blur to the copied layer

3) Change the blending mode to Screen. Experiment with othe blending modes for your taste.

4) Adjust the opacity.

Is it possible to do that in the the new vray version? saw some sample pics of what the vray physical camera can do. it's really amazing. too bad i can't aford an upgrade right now well i guess ill just stick with my 1.46 for now and my dependable photoshop CS. Thanx guys

Again in Photoshop, you can also use the Diffuse Glow plug-in, free from Richard Rosenman on his website.

As there are many techniques to do this whether with a shader, video post , etc.. i always prefer post as it gives the best control, especially when u're doing an animation.

So here's how i do it (Photoshop, After Effects, Shake, Fusion, etc...)

Bloom is generally generated by bright areas in the picture, so what we will do is:

Duplicate the image to a new layer

Select->Color Range> Highlights (from the drop down box). Check also the invert box then OK.

This operation selects the inverse of the highlights.

Now Click on backspace to delete this selection. We are left with the highlights. Now change the blending mode to any of these: Screen, Hard Light, Soft Light, Vivid Light. Personally i find that Hard Light gives me the best job. Now Do a gaussiaun blur, motion blur (experiment). Try small and large radius and see how the final effect changes. Of course you can tone it down by changing the opacity of th layer, or creating a Layer mask and with a soft brush (grey) paint the areas you want to tone.

 

Hope this helps

here's an excellent tutorial on doing it in photoshop.

This site has been a great resource for jumping into Vray. I would definitely check out some of the other tutorials too. It has step by step stuff but also goes into good explanations of how and why.
