• Image Size and Quality
It is recommended that exported images are resized so that their longest side has 2008 pixels. This size results in good image quality for all iOS devices and is suitable for AirPlay and external monitors.
However, there are a few situations in which you may wish to change this default size:
- If you are using a high-definition monitor you may wish to increase the size of exported images.
- If you are using an iPad 2, iPad mini, iPhone or iPod Touch and you are not using AirPlay or an
external monitor, you may wish to reduce the size of exported images in order to save space. The following
table gives the receommended sizes for different iOS devices.

Depending on the aspect ratio of the cropped image in Lightroom, with the recommended settings an exported image will contatin roughly 2 to 4 MBytes of data.
For many images, lower JPEG quality makes no descernable difference. Therefore, to give users more control over the amount of storage required for their galleries,the GalleryLR plugins offer three preset quality options - Low, Medium and High.
The following table gives typical data sizes for images exported with the different options.
|Image Size||JPEG Quality||Images Size (KBytes)|
A JPEG Qaulity of Medium reduces image size and in most cases, gives acceptable image quality.
