I need to use 2 different exposures to photograph a house/sky. Can this be done in jpg? Will photoshop 6.0 allow me this privelege? How exactly are the 2 photos fused together?
Just trying to get a sky and house properly exposed but the sky isn't cooperating. We have no blue sky with clouds lately so I need to tone down the sky tones and bring up the house tones.
Any help appreciated. |

| just copy and paste one over the other as a second layer and mask out what you don't need of the second layer. |

If you shoot in RAW, you can then process two different "originals" from that and re-combine them in Photoshop. If you must shoot in JPEG, you'll probably have to take two identical shots (us a tripod!) with bracketed exposures and try to recombine them.
You can also try shooting with a Graduated Neutral Density filter, which will darken the sky while leaving the foreground relatively unadjusted.
If you must use a single exposure with this problem, you can try making the tone adjustment (e.g. Curves) through a graduated mask.
As far as combining the two images, you can put them on two layers in Photoshop, and then adjust the opacity and blending mode, or else erase the parts of the top image where you want the bottom image to show. |

You can get a trial version of Photomatix Pro here. This program lets you merge two exposures (or more) of the same scene for greater dynamic range. It works very well. The trial version does not have full functionality, but the part that IS functional is the part you need to use, so give it a try. It's very easy. It works with JPG, TIFF, and PSD, but not RAW files. So if you have RAW, you need to convert them to TIFF or JPG, but you're doing that anyway since PS 6 doesn't have RAW functionality built in.

I'm not sure of PS 6, but if it has the HDR option, you may want to use it.
In PS 9 you can find it under File/Automate/HDR. See if PS 6 has it, at the very least test the option to see if you like it.

If you have a flat exposure with neither blown highlights nor blocked shadows, you ought to be able to process two images (like with a RAW file); one you adjust for the best shadow/midtone detail and ignore the highlights, the other work on the highlights and ignore the shadows.
Place those on two layers in a new document and erase away the parts of the upper image you don't want.
It would be helpful to see the shot (or similar) to what we're trying to fix : ) |

This is a good suggestion. It is a simple concept and straightforward. It only depends on your ability to mask, a skill all photographers need.
Another masking approach you can take is to do a sky replacement. In this approach you do a sky selection first and save it. It can be done a variety of ways depending on sky/horizon contrast. Color Range selections often work best. Magic wand can work depending on how distinctive the sky is from the ground. There are many other techniques to. Then open the sky selection in the channels pallet and do hand mask touchup where you see the mask superimposed on the image. Often little hand work is needed. When done be sure to click off the mask so it does not display when you go back to the layers pallet.
Assuming you pasted the sky layer on top then click on that layer and attach the sky mask to it. With the sky layer hightlighted select the sky mask from "Select->Load Selection" and chose it by name from the popup menu, give it a small feather around a pixel or so. Then either click the add mask icon or select "Layer->Layer Mask->Reveal Selection" and you are done.

Well guys...this is what I came up with. I layered my 2 exposures in photoshop. Editing is not perfect, but I printed up an 8x10 and it looks great! Thanks for all the help. This photo will be hanging in a local restaurant soon!

Good job Kel. You could probably squeeze even more detail out of the shaded tree areas, but not bad.
