View Full Version : Gassian Blur Overlay?
09-01-2003, 09:57 AM
I've recently discovered this technique. It seems a bit too far to go for this website, and I haven't noticed any use of it here. What think ye? It sure makes a lovely picture, when used right.

I use a gaussian blur overlay as a part of contrast masking which is something I do for almost every photo. Is this what you are describing? Or, are you more simply talking about using the gaussian blur to create an out of focus effect? I know that for some of the shots with my digital camera, which has too great a DOF for portrait style shots, I will do so, although for those types of shots I usually use my SLR, where I have more control. Either way, I have no problem at all with such a procedure, as they may change the effect slightly, but for me they don't change the reality.
I'm intrigued how "gaussian blur overlay as a part of contrast masking" works, could you elaborate on the practice and theory. Thanks
Maybe there should be a specific box on the image uploading page where one can outline any image editing that has taken place in the same way one can leave a description of their picture. This may prompt more people to leave details...

Hi Tuc. The contrast masking method is something quite a few on this site use, and I think it can benefit almost every photo. I found out about it at http://www.luminous-landscape.com/tutorials/contrast_masking.shtml. The author here does a far better job at explaining the method and the reasons than I ever could. I view this as being an indespensible technique for processing photos. All this being said, I am not at all certain it is used in the same manner as what David was asking about.
Thanks Darren, it really makes a difference.
I think I may have hijacked Darrens forum, for which I apologise. But to any other Photoshop novices out there who have not tried this technique I would recommend giving it a go.

My technique is described at this url:
It is used to make a soft focus look--almost a glow if done right. It IS digital manipulation post-processing, and I haven't seen it on this site (so you all must be really good at it if you use it!). I'll post one someday and see what kind of comments I get.
I've also learned that the technique can be played with and simplified by simply creating a background layer, using gassian blur just a little but without using the Multiply option described in the fine tutorial. It's fun to play with. Try it on some shot where you want a dreamy, nostalgic look!

I've seen (in a magazine) a process which creates a really incredible result rather like this, but more so - but it's done with slides. Take one phot (must be a transparency) very out of focus - think out of focus, then make it even more out of focus. Take another pic in focus. Take the two transparencies out of their frames and sandwich them together in a single frame. The result should be a very blurry haze surruonding sharp centers, especially where light areas overlay dark areas. I just can't find a way to do this in Photoshop, but it must be possible - this sounds the closest yet.

I've just gone through the technique described in Luminous Landscape and come up with a result that I can only describe as extremely weird. But extremely effective also. But there's one thing I've done that's not described ni Luminous Landscape: at the very end of all the steps, I ended up with three layers in this order (starting at the botom): Background; Background Copy, with a very heavy use of Gaussian blur, maybe as high as 40 pixels, and set to Multiply mode; Adjustment Layer for Levels, used to increase brightness. My extra step was simply to reverse the order of the top two layers, so that the Background Copy is now on top and Levels in the middle. This is now getting close to what was described in the magazine, and maybe what is intended in Luminous Landscape, but the instructions in Luminous Landscape don't seem to lead to the same final order of the layers (not the way I read them, at least).
I'll post the result in my portfolio (I'd make a link but I don't know how to do it). It's a photo of a baby, just so's you'll know.
