A compression of 5~6 gives the best time versus file size yield. In IrfanView and ImageMagick we can control the quality setting from 0 (uncompressed) up to 9 (max compression). It also explains why IrfanView is so much faster and still produces nicely compressed versions. This takes about 33 seconds compression time per image with my benchmark images. Next, I checked the "save for web" option - which resulted in the long wait times again, because it seems PS automatically sets the compression rate to one of the highest (8 or 9). Then, however, I noticed the reason for this: no compression is applied at all by PS, and the resulting PNG files are huge, this being the nature of uncompressed PNGs. I ran RB's image processor on the same list of images as before, and was surprised to see it converted all the JPGs to PNGs in a matter of ~10 seconds. But it is much slower than IrfanView, a tad faster than PS.Īfter some more testing I have to partially retract the words I have written above. It is a command line tool, and easy to use for conversions.Will also work on a mac.

ImageMagick is also free and open source. The batch processing you can find under File->Batch Conversion

This matters if you have hundreds of images to convert.ītw, Irfanview (windows only) is free to download It's too slow.Īnother issue is that during the conversion process Photoshop cannot be used - while with a simple conversion utility you can leave it running in the background, and continue to use PS for other work if required. That's a rather big difference - and with large numbers of images I just do not have the time to wait for Photoshop to finish the job. For example, I did a quick test to demonstrate the difference in performance:įolder with 10 images in jpg format, 5600px by 5600px. Photoshop is incredibly slow for this type of work. Compression rates of 10:1 or 20:1 yield little degradation in image quality.But can I be honest? I'd do that with a more efficient and far faster conversion utility like IrfanView. Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). JPG is a graphical file format for editing still images, it offers a symmetrical compression technique which is processor intensive and time consiming in both compression and decompression. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth. The JPG format is often used in digital camera memory cards. The resultant 'lossy' file means that quality can never be recovered. JPG's are often used for web sites and email as they are generally smaller file sizes as they are lossy meaning that some image quality is lost when the JPG is compressed and saved.

The structure of RAW files, including the ISO standard RAW image format ISO 12234-2 follows a common pattern - a short header, camera sensor metadata, image metadata such as exposure settings, camera and lens model, date and sometimes the location. RAW image formats are intended to capture as closely as possible the characteristics of the scene to include light intensity and colours. RAW files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor. RAW file formats contain minimally processed data from the image sensor of the digital camera - the metadata includes information about the lens, the settings, the camera’s identification and other data. NEF otherwise known as the Nikon Electronic Format is Nikon's RAW file format.
