The upshot is that I end up with multiple copies of the same photo that take up storage space on my hard drives. The good news is drives are huge and inexpensive, so it's very possible to store thousands of photos and still not fill up a single drive.
The process I use to avoid problems is:
- Shoot your photos at the highest possible resolution. You can never make copies sharper than the original but you can always "dumb 'em down."
- Make my exposure adjustments to the original shot so the colors and lighting are best.
- This is where the time-consuming aspect comes into play. I always make a copy of the original before cropping or resizing it. This way I have unchanged original to fall back on if I don't like the crop or new size.
- Assuming I like my cropped version, I'll save a copy of it (copy #3) at a specific size and/or resolution, depending on the photo's intended distribution and use.
Also, the format you save the file in is very important. I like JPG ("JPEG") for email distribution because of its universal use. PNG is becoming very common as an alternative, but far fewer folks will be able to see these shots.
JPG graphics allow you to set the compression amount, which affects the quality. Little or no compression (9-12 on the 12-point scale) means larger files, which translates to longer upload and download times, but better viewing and printing quality. Medium to high quality (6-9 on the JPG scale) is usually enough for most emails, though.
You set this quality level when saving the file as a JPG. Hitting the Enter key twice saves the copy at the same resolution as the last shot and locks the file. The first time, though, lets you adjust the compression and quality from ultra small, low quality, to huge, high quality.
Another key step is naming your files so low-res copies don't overwrite high-res originals. Here's an example:
- Original or copy 1: Filename.RAW. Because I use an interchangeable lens digital camera most often, I can save photos in the RAW format that retains all of the original exposure information, including the ability to adjust the exposure after the fact.
- Copy 2: Filename.PSD. I'll save a copy in the native Adobe PhotoShop format if I've significantly altered the image, such as by adding text (see my Christmas card as an example).
- Copy 3: Filename 4x6.JPG. This is the high-res version for general print distribution. My originals are shot at even higher resolution, so making a 4x6 print is still lower quality--and makes for significantly smaller files--than the original.
- Copy 4: Filename 4x6-72.JPG. The "-72" tells me this version is for email distribution and on-screen viewing only.
That's the lengthy, step-by-step process I use. Hopefully it will help you keep your digital photos organized.
