Saving Images: Resolution and Format

Tip: Be sure to save your digital images offline even if you use an online photo site. Consider storing your images on a Photo DVD (pictured above) a Photo CD, on a digital media card or on an attached disk drive. That way, you will always have access to your original images in their original size and format.

When you upload your digital images to an online storage provider or photo site, be sure to check out what size image they store.

Some size re-size your images in order to make their storage more efficient. I was making a photo book for a friend and she sent me a Photo CD that she had ordered from her online provider. I loaded the image onto my computer and made the book. When the photo book came back, the images were very low resolution, looking grainy. I'd seen this many times before, so I took a look at the file sizes and sure enough the image on the disk were less than 200k! I'm guessing that the original files were some where around 5 megabytes.

I went to the online photo site that she uses to see what their policy was and after some looking found that they defined "high resolution" image size as 1,000 x 1,000 pixels. A camera that takes 12 megapixel images has an image size of 4256 x 2832 pixels. I checked another well known photo site that specializes on photo books and they "suggest" using 1,280 x 1,280 pixel images in their full page 8 1/2" x 11" photo books.

You might also want to check out what type of digital press they use to make the photo book and the settings they use on the press to print. I've seen photo books printed on a number of presses and there really is a quality difference. We like to use providers who use HP Indigo presses. we have a very picky retail partner who will only allow the use of the Indigo press for printing her customers books.

So why do they downsize? Simple, when you are storing millions (or billions) of images, the larger the file sizes, the more costly the bandwidth and storage. I talked to one online site that used to store 600 x 600 and upgraded to 800 x 800 and it cost $35 million to do the upgrade.

Be careful with downsized images. You'll run into big problems if you ever want to make a larger print or crop the image.

Working with Walgreens, aVinci Media has introduced a Photo DVD Archive product. The Photo DVD not only stores up to 4 Gigabytes of images (7 times the capacity of a Photo CD) but it also includes a free slideshow using forty (40) of your images set to music. You can watch the slideshow on any TV or Computer with a DVD player. The product is available on the in-store photo kiosk. As of January 15th, it is available in approximately 2,000 stores. It will roll out to all Walgreens stores in the next 30-45 days. The cost is less than $8

Scanning Old Photos

I came across this image in a bunch of my grandfathers things. The problem was that it was just a 4"x5" Black and White negative. It is important to me for two reasons. First, my grandfather loved the Indians. Second, I still have the headdress that he is wearing. When he met these fellows, they were very, very poor and were quickly losing their culture. He helped them make the headdresses that he and the chief are wearing. He also worked with them, teaching them how to make drums, one of which I still have.

Anyway, I wasn't sure what to do with the negative and how to get at least a reasonable image. I opened the regular scanner bed and set it directly on the glass. I then removed the white backing on the scanner so that the light used to illuminate negatives was exposed. I did not use the slide/negative carrier since the negative was too large (You'll note I could not get the entire negative, so I settled for the faces). I set it in place and then set the scan to "film" and "b&W". I used 600 dpi setting. HP has some nice tips for scanning at the following link:

When I got it, it was a little washed out, so I used Adobe CS2 and cropped it and then used "Auto Improve". It added some dense black to the image and for taking a couple of minutes and costing nothing is a pretty good option. Now that I have the image, I'll take the negative to a good pro Photo Shop like Inkleys.

By the way, these are "Shivwits" Indians from around St. George Utah. Grandpa has the moustache.
