What are available display sizes?
With SmugMug, you get to keep every pixel forever and show them as big as your screen will allow. Upload once, and we'll make up to 8 display copies from each file.
The 9 sizes of SmugMug:
|Pixels wide||Pixels high|
|Tiny thumbnails (-Ti)||Up to 100||Up to 100|
|Large thumbnails (-Th)||Up to 150||Up to 150|
|Small (-S)||Up to 400||Up to 300|
|Medium (-M)||Up to 600||Up to 450|
|Large (-L)||Up to 800||Up to 600|
|XLarge (-XL)||Up to 1024||Up to 768|
|X2Large (-X2)||Up to 1280||Up to 960|
|X3Large (-X3)||Up to 1600||Up to 1200|
Example: If your original photo is between SmugMug's Large and XLarge sizes, we'll only create the Small, Medium, Large, and Thumbnail display copies.

It's possible to wreck how your computer displays photos, with just a few clicks.
Speed optimizers like Earthlink Accelerator and NetZero HiSpeed can destroy image quality. See this article from PC Magazine.
AOL image compression does the same thing. It's on by default but you can turn it off.
The settings for your display (or the displays of people you share with) can make a huge difference.
For Windows, set the number of colors available for display by going to Start > Control Panel > Display > Settings. The dialog you see below should display.
A setting of 8 bits (only 256 colors) does not allow the computer to display photographs well; 16-bit is much better, and 32 is best. You may have to upgrade your graphics card to see the 32-bit option.

Resizing and Sharpening
SmugMug uses the Lanczos algorithm to make display copies because it preserves the most detail. It is not often seen in software like Photoshop because it is CPU-intensive.
Any time an image is downsampled (to go from your original to SmugMug's large display size, for example), the image loses sharpness. The usual way to restore sharpness is to apply unsharp mask. A typical value, and Photoshop's default, is 50%. By default SmugMug applies only 20% (0.20) because Lanczos does not lose as much sharpness when resizing.
Our default, shown in the center photos below, is a compromise between landscape, product, and wildlife photographers who like their images sharp, and portrait photographers who prefer a softer look.
If you have a Power, Portfolio, or Business account, you can set the amount of sharpening on any gallery in your gallery settings. You'll find the three parameters you're probably familiar with (amount, radius, and threshold) and an uncommon one, sigma. Amount is the parameter most often changed.
Here's more advanced info on how our parameters compare to Photoshop, and what sigma means.
These settings do not alter your originals. Prints are made from your originals so increasing unsharp amount can mean your photos will look sharp online but soft in print.
We'll use your sharpness preferences if you're a Pro Smugger and sell a 1 Megapixel or 4 Megapixel digital download.
Note: When you change sharpness settings, they apply to images you upload after you make the changes. They do not alter past uploads, unless you do something that will cause us to make new display copies, such as rotating photos.
