Do you really have to (sometimes painstakingly) brush in the exact same area for each different adjustment?
Yes, you do.
Unless you can use one of the predefined selections for the brush range, like shadows, midtones, highlights. And it helps to turn on edge detection.
The masks for the brush range are stored in the user library: Each time you brush, a mask like this will be created.
~/Library/Application Support/Aperture/Adjustment Preset Brushing/2/2y/2yUD8JFfTqaTVtuztg9h%Q.tiff
If you can find the mask you created, you could try to use it again for the next brushing, but that would be a risky operation.

I wonder why they have assumed people using Aperture would not find that omission tiresome.
Anyway, I have another issue now.
I have only just found out that my Canon EOS 550D images which I have enhanced are only 72 dpi/ppi. I don't know if they will produce satisfactory enlargements (only to about A3 size).
My scanned images are all 300dpi.

Where do you see this? After exporting the enhanced version? What is the export preset that you are using? By default Aperture uses the 72 dpi setting on exporting. If you want a different dpi setting, you need to edit the export preset. But have you checked the pixel size? Even with a lower dpi setting you should get exactly the same resolution and pixelsize as the original image file has, if you export with an "original size" preset.

My comment about the ppi was not really Aperture related.
The images come off the camera as 72 ppi, which seems low when 300ppi is usually recommended for printing.
I have spoken to Canon today but have not got a conclusive repy yet
Sorry to mislead you

You may want to take a look at a somewhat detailed article I wrote on this subject for my blog, including step-by-step instructions on how to copy a brush mask from one adjustment to another.
Hope this helps!

It's just a setting. It has no bearing on the actual data. Some programs use it to determine something called "the logical inch". Aperture does not. You can attach any DPI setting to files you create by exporting from Aperture. It still doesn't really mean anything, and can be safely ignored. Neither DPI nor PPI measure a digital image's quality. If you print an file at 300 PPI, it is likely to look, under normal examination, as good as the file can look. If you print a file at 4 PPI, it will surely look pixelated under normal examination. Note, first, that the file has not changed. PPI can be a measurement of something we associate with the quality of a _print_. (Again, it has no bearing on the quality of an image file.) Note, second, that the 4 PPI print is 75 times larger than the 300 PPI print. Perhaps it's a billboard. Seen from the distance billboards are seen, it is probably pretty sharp.

Thanks for the replies on brushes and ppi
I appreciate your article John, but I don't think I am computer savvy enough to risk tinkering with files not knowingly generated by me.

That may be true but you'll never gain the knowledge if you don't give it a try.
And while you won't want to experiment with your actual library you can always create a new library just for test purposes. Add a few images to it and then try out different things you'd be amazed at how much you can learn when you're not afraid of messing up your real work.
