how to make fading background homogenous

[pure]

hi,

i got 10 pictures. they have a fading background from white to light-beige.
in the front is a model, standing.

is there any easy way, one-click-like, to make the backround free of the big blurred spots and stains in the roundwall? the spots are very light, you cant hardly see them, but if you want you can see, thats the problem,

i am doing it manually in the moment, with a big soft brush and copy even areas to the non-even. but it takes much time.

thanks

It would help if you could post the image.

hi pure,

i would think, with such strong contrasts in colors there, that you could simply use a FILL brush. sample the white you want to keep and simply use a FILL. if it tends to run into the red a bit, why just make a feathered selection first and then FILL.

whats a fill brush sorry?

is it the thing i use? only know the german expression, it looks like a stamp.
its a bit diffcult to fill somehing there, as the gradient fades to white above also ground is white. also there is the model. and i dont want to extract here only because of that. hm. any filter? i tried blur. hm

pure,

see the attached. this is a screenshot in paint shop pro, but it's going to be pretty much the same in photoshop. sometimes it's called FILL and sometimes PAINT BUCKET or something close to that.

i did mine with the FILL at a 21% tolerance. the tolerance sets how much differentitation between the color you're using and the colors that it fill vary.

also, you REALLY need to get this german language version thing sorted out. MOST of your posts are because you simply cant read or translate the version you're using. you shld be able to go to the adobe site and get a .pdf version of the manual for free....IN A LANGUAGE YOU CAN READ! i just hate seeing you struggling with something that is keeping you from doing what you really want to do. get the version of the manual you can read! we love to help, but something like this vexes all of us, especially you. so, let's get this sorted out.

sure, sorry for this. i know what the fill is now.

actually i meant it different:

the gradient in the back should remain as is,
i only would like to make it even and look homogenous. there are bigger and medium big blur spots in the gradient, which seem to be a bit darker, you can hardly see them only if you look around (not the small ones, these i can remove manually)

probably you know what i meant...

thanks

I went though the blue channel and cleaned it and then selected that part of the channel (without the red) and copied it into the the other channels and this is what I turned out with. From there you could fill it with a gradient in layers.

ok thanks i try

I will mask the girl and make the gradient again for a pure white background

I work in a studio with a typical painted white floor and walls for high-key white portraits. The floor gets terribly dirty. To clean up the floor, I created an action that uses the Noise - Dust and Scratch and about 15 pixels, then back it off in History, and apply the Dust and Scratch in the History Brush. Grab the History Brush, select about a 300-400 brush size, then stop the recording for the action. Make sure you use a hot key when setting up the action. Then, hit your hot key, wait for your History Brush to come up, and start painting the effect where you want. It smooths away discolorations, dust, whatever falls under that 15 pixels. Beware that the more pixels you use, the longer it will take when rendering the effect.

When I have a set of proofs to cleanup, I use the automate batch and apply it to all open files, walk away and grab a cup of coffee, when I come back, I'm ready to rock.

12, that sounds good. i cant follow what you do in specific, but nice.
i never understood the history brush, but i can imagine a bit what you mean.

my inital goal was to receive the same background as it is in the original picture, (not a complete white one) only without the smeared blurs in the middle, a bit darker as the beige. sorry for being not clear enough.

i tried a soft brush with stamp-tool, very big at 20% transparency. then i wiped/copied the blur away. i dont know if there is a faster method?

With an image with lots of contrast like this, use the Dodge tool.

On the toolbar at the top set Range to Highlights set exposure to about 25%.

Now just brush across the BG. Because it's set to highlights, your darker contrasting image will not be touched.

Unless I misunderstood your request, using the healing brush in PSCS2 should work however it's not a 'one stroke fix' ...

[Kraellin]

this shld work in ps or in psp. make a selection of the off-color area. adjust it with the modify options as needed to get only the off-white area. copy the selection to a new layer. use a heavy gausian blur to blur it. i used a value of 65 here. blend the blurred layer back onto the others with a soft light blend and that shld do it. this may not be exactly what you wanted, but you could vary a few of those things a bit, either the selection or the blur, to get closer to what you're after.

thanks very good help!

actually i need both of your methods, one with beige stripe, one totally white...

all right

Make a selection of the background--in the easy example you posted, I just used the magic wand. If you want to be absolutely sure you aren't encroaching on the subject, you might contract the selection by a couple of pixels.

Then put this selection on a new layer all by itself (in paintshop pro, this is the "promote selection to new layer" command, in Photoshop I think the command is something like "create a new layer from copy"--it would be in the layer menu.) You still want to have the background selected. In paintshop pro this happens automatically, but as I recall in photoshop, it clears the selection, so you'll need to preserve the selection somehow or reuse the magic wand on the original layer--I'm sure there's an alt-ctrl-shift-tab-key combo that does this :-).

With the new layer active (this is the layer with only the background on it) do a gaussian blur (or any blur will do) of maybe 30 or more to smear out the blotches without killing the background gradient. You're done in 30 seconds.

This will work as long as you don't have severe blotches right next to the subject. If that is the case, then I'd use the object remover tool (PSPX again) to remove the object completely, replacing it with an extension of the background. The closest thing to that in Photoshop is the healing brush, but I'm not sure how well the healing brush works on a huge thing like an entire person.

I attached the layer palette and result for the "simple" procedure.
