Just don't export every single image separately. Do all your edits in Lightroom and just select all photos and export with a preset. When the first preset is done, just export with the second preset, and so on. Just create presets with naming and file formats, sizes beforehand. Then, the next time you export all selected photos, you can use (for example), ...


JPEG issues aside, downsizing images will result in a loss of sharpness. Furthermore, printing will result in a loss of sharpness too - the extent of this depending on the particular medium you are using. This is what output sharpening is used to counteract. You can read an explanation of output sharpening for web and print in this article, which has some ...


You can reduce the quality, then it becomes smaller. For this you can use GIMP, Photoshop, .. Are you sure that you need such a bad quality?


JPEG2000, and you may also want to look at OpenEXR because it is supported by video hardware.


The maximum dynamic range of a linear 8-bit encoding is only 8 stops, however the dynamic range you can store with a nonlinear encoding is limitless. Thus I would suggest you apply a strong tonecurve to the images and then you can use standard JPEG without losing dynamic range. When you want to use the original images, convert them to 16-bit and apply the ...


It sounds like what you're looking for is JPEG2000. It has a range of options including a 16-bit lossy compression and better compression ratios than JPEG. It hasn't been as widely adopted as hoped (for a host of reasons) and may have some patent issues that might make it difficult to use in certain situations but otherwise it fits your needs. Personally ...


Yes; if you edit the image (for example, to resize) and save, there will be new degradation from JPEG artifacts. If you saved (and resave) at a very high JPEG quality, the difference will be negligible. You could avoid this by saving in a lossless format like TIFF instead after your edit.


Nope. From a manufacturers point of view, it wouldn't even be a different camera. They'd sell the exact same camera with some firmware that prevented jpeg compression. When it comes to integrated circuits, mass production is where the money comes from. A product with reduced feature set is often just cannibalised with a special firmware. I remember how I ...


There is no justification for removing JPEG processing in digital cameras for the foreseeable future, there are plenty of reasons not to use jpeg but none to make it completely unavailable. From a performance perspective the biggest bottleneck is writing the file to storage card(s) and mandating bigger files would yield no speed improvement at all. Cost ...
