Pentax has launched version 2.1 of Pentax Photo Browser and Photo Laboratory Updater software which improves usability for *istD and *istDS owners. New and improved points in the Photo Browser software for the *istD include changes to print function, the ability to view next and previous images in the main image window as well as a search function. Photo Laboratory 2.1 allows you to change the size of the preview window, something which was criticized in our review of the *istD software. For *istDS users the software allows thumbnails to be displayed quicker and improves the image quality of RAW-processed files, amongst other changes.
