There are several reasons to shoot RAW and JPEG: Just to recap: RAW is the information the camera gathers from the sensor, without (or just a bit) modification. JPEG is a lossy compressed image, which is created out of the RAW file according to your settings of film simulation, dynamic range optimisation, noise reduction and so on. In short, it misses ...
As I don't have any extra photo editing programs I used iPhoto to do this. Open iPhoto with the option key held down. This gives you the option to create a new library. Create a temporary one somewhere where it will be easy to find and delete it later. Import all the Raw Pictures into the new library. Export them all in the required format. Quit and delete ...
If you are not afraid of the command line you could use the tools by ImageMagick mogrify -resize "3000x3000>" -quality 85 *.jpg 3000 here is just a number of pixels, > guarantees either width or height to be of that size. 85 determines the quality of you batch images.
Try Irfanview. press the key 'B' will open a seperate menu for batch conversion. there you can add any no of images, you also have an advanced menu. http://www.irfanview.com/
XnView allows you to batch process files, while adding all sorts of filters. You can probably achieve something similar as "sharpen, quality 38, blur 0.3" by fiddling a little bit with all the options and filters.
Have a DOG sniff out blur in the photos. If you're going to be penalizing for digitally enlarged photos, you might as well penalize for out-of-focus photos too. The blurred edges and details in both cause the same bad experience for viewers, regardless of whether it is caused by a small original or poor focus. What you want to do is detect blur, which is an ...
I do not that this is possible in the general sense. There are many possible upscaling algorithms, with a signature that may be difficult to detect unambiguously without knowledge of the image content (as an extreme example, an upscaled area of uniform colour is still uniform colour...). Possibly an option would be to calculate a metric for image ...
