Hi folks, would someone be kind enough to help me even out some lighting?

I have a group of eight people in a two-row pose. The left four people are next to a window and so they are lighter than the right four. I’m sure there is a way to lighten the photo so that only the necessary areas are affected, but how?

Thanks in advance for your advice,
Jo

if you can retake the picture i would suggest holding up a large piece of white paper or similar object to reflect the light back onto the right 4 people

if you can’t retake the picture try making a gradient mask going from transparent on the left to opaque of the right and them try using levels, brightness, ect. to fix it

Quick and dirty method:

Copy your photo and save it as something other than the original. Work on this copy. Use the lassoo with a wide feathering (try 100 pixels to start – you will see if the transition is too dramatic or not) to encircle whichever part you want to adjust. Use curves to fiddle with the tones in this area and perhaps history brush to adjust sections you overdo. There are better methods such as adjustment layers but as I said above quick and dirty.

Yes, this is exactly what I would like to do. Would you be kind enough to explain in a bit more detail what I need to do to achieve a gradient mask?

As stated, the first thing to do is to work on a copy, not the original image. Next (and the order can vary), create a mask, by hitting Q. You will have nothing shown at this point. Choose Gradient Tool, and select a Linear Gradient that goes from denisty to transparency – there is one in the default group of Gradients. Click on one side of the image (remember, you are in Quick Mask Mode), and, while holding Shift, drag to the other side. In the default Gradient, you get density (red) going to transparent at about the ~ 50% mark. you can vary this graduation by either dragging to a point less than 100% of the image width, or by adjusting the point in the Gradient Options dialog box. You now have a Gradient Mask (experiment, as you probably want >50%, or < than.) Now, hit Q again, to get the "marching ants" and then choose the Adjustment Layer icon at the bottom of the Layers Palette. Here, you can choose Levels, or Curves, as you choose, to correct density, and contrast. If you have not hit the point right with the mask, you can always go back and re -do it. When you have the Curves, or Levels correct, go to Selection, and choose Load Curves, or Levels Adjustment Layer Mask. You will get the marching ants again, and now click again, on the Adjustment Layer icon. Now, choose Color Balance, and tweak the colors.

You can do the Adjustment Layers, and THEN add the masks, if you wish. When changing/adjusting the masks, make sure that the mask’s Channel is active, by either clicking on the Adustment Layer Mask thumbnail, or by clicking on that Channel in the Channel’s Palette.

If, for instance, the graduation of lighting is not near the 50% of the width, then use your best guess when doing the mask.

If this is not clear, don’t hesitate to ask for more detail. It takes much longer to type this, than it does to actually do it, so do not be put off by the length of the text.

Adjustment Layers are your friend, and their masks are totally marvelous.

click icon to enter quick mask or press keyboard shortcut (q) with default colors selected (d) select gradient tool
select linear gradient mode in the toolbar at the top
drag a line from right to left
the redder the area is the less it will be affected
you may need to adjust how far you draw the line to get the area you want selected
click icon to exit quick mask mode or press (q)
use levels, brightness, ect.

I have to say, that is an excellent solution to her problem. One thing that must be noted, however, is that in Photoshop there is always more than one way to do something correctly. The solution posted is an excellent way to vary an adjustment over distance if there is a linear brighness error. This technique also works for images taken with cheapo cameras where the corners are darker than the center. Using a Radial gradient in the center of the image instead of a linear blend across the image will make these images easy to correct.

Another possibility for you might be a trick I use often, (I have a pen tool, so this would be more valuable for someone who is using a pen).

As noted, work on a copy or duplicate of the original… create a layer ajustment layer above the image in the layers palette. Adjustment layers automatically create a mask when you make them. (Look to the right of the adjustment layer icon in the layers palette.. you will see a blank white box).

With layer masks, white in the mask reveals the effect of the layer mask, and black will hide the layer mask effect.

Adjust the layer mask until the area you are trying to fix looks proper. Ignore the fact that everything else is going to hell — just pay attention to the problem area and make it look as good as you can using the adjustment layer. Once you are happy with the way it looks, apply the layer adjustment.

Now, click on the white adjustment layer mask, and hit Control-I (CMD-I (Mac)) to invert the mask. Now, the image will look like it did before you put the layer adjuster onto the image. The Adjustment mask icon will now be black instead of white.

Being sure to click on the mask icon, and set your pen tool to be white, with a soft edged brush of appropriate size and start painting where you want the adjustment to be applied. As you paint on the mask, the Layer Adjustment will be applied. The softer the brush, the more subtle the effect will be.

Hope that helps…

Oh, and if you paint on the masking layer with black, instead of white, you will hide or diminish the correction effect…. (Left that out of my previous post)..
