Canon 12x IS USM (S3 IS built-in Lens) -- 36-432mm (35mm EQ)

Hi gang,
Hoping to see if you guys can come up with some solutions I haven't thought of.

I am compositing some images for a client. They have provided the source images in jpg, the one I'm struggling with is a large jpg of Grand Central Terminal in NY.

I shot RAW files of the models in my studio to fit into these locations. The model images turned out great.

The idea for this image is to apply a Ken Burns effect, starting zoomed in on the model holding the product, and then pan out to reveal the location. The problem is that when I insert the model into the source image and reduce him to scale, there is a great loss of detail. I've tried enhancing the image, running sharpening, upscaling in a separate file and then inserting in the location image. It always results in a loss of detail.

Is there a way to overcome this? Or is it the result of limitations due to the background being a jpg, or the model's reduced size in the grand scheme of the scene?

I think you might need shoot the models from farther away with your sharpest lens/settings so that the scales between the source images isn't so large.

Or you might try better-quality upscaling software on the image of the terminal to closer match the scale of the models (and add more memory to work on the composite?).

I might have other ideas if I could see the images, but I understand why you're not posting them ...

Thanks Paul. Unfortunately, a reshoot is out of the question. It looks decent enough if they zoom in to his full height but not as close in as they want.I've already mentioned a smaller scale location as the last resort.

What about using topaz gigapixel and resize the location photo significantly larger?

You need to go the opposite way... upscale the background to the scale of the model. Otherwise no matter what you do, you will lose detail when the model is scaled down to match the background.

By the way, lightroom or photoshop (I cant remember, now has this capability. But I've tried Topaz Gigapixel and it worked great

And I get good results with On One's Perfect Resize - I have very old software

Excellent idea. I'll try upsizing the background shot.

FWIW, It sounds like Johanna has high resolution versions of both the model/product and the location. She is losing the resolution when resizing the model/product to match scale.
She needs to avoid that severe down-scaling of the model/product, and the way to avoid that is to instead *upscale* the location image to match the scale of the model/product.

That was my second suggestion ... ;-)
