| | Lightroom renders three types of previews: thumbnails, screen resolution images, and 1:1 previews. 1:1 previews have the same pixel dimensions as the original photos. All previews are stored in the folder where your catalog is located. |
| | # Choose File > Catalog Settings. |
| | # Choose from the following menus: |
| | #* *Standard Preview Size* Specifies the maximum pixel dimension for the rendered preview. Choose the size that accommodates the display size you're working with. |
| | #* *Preview Quality* Specifies the appearance of the previews. Low, Medium, and High are similar to the upper range of the quality scale for JPEG files. |
| | #* *Automatically Discard 1:1 Previews* Specifies when 1:1 previews are discarded. 1:1 previews are rendered as needed and can make the library preview file large. |
