A1 - rotate portrait orientation imagaes?

[enry68]

If Minolta adds in A1 firmware a feature, that can be activated with a button, that rotate directily the image the problem may be eliminated. To do this automatically the camera must to have a position sensor and this is impossible to add now.
The rotation if has made by the camera is better because it works directily with the bitmap and not with a compressed one, so there is no lost in quality.

Enry.

IrfanView has a "JPEG Lossless Transformations" plugin

Another one to consider (and which doesn't require a plugin) is PIE (Picture Information Extractor), which also has lossless rotation.

IrfanView has a "JPEG Lossless Transformations" plugin. If installed, it can be found under the OPTIONS dropdown menu, or using the Shift + J keyboard shortcut. It includes flips and rotations, plus optimization, etc.

Even better, if you select Irfanview Thumbnails ("File | Thumbnails"), there's an entry under "File" for "JPEG lossless transformation for selected thumbs" which lets you rotate all the portrait format images from a whole cardful at once. Remember to work on *copies* of the files, as the input file is overwitten in either method.
