Casio EXILIM Pro EX-P700 Review
Output image file quality / JPEG artifacts
Standard Test Scene
The P700 provides five different output image size options, three different JPEG compression settings and an uncompressed TIFF mode. Additionally there is also a 3:2 aspect ratio size (3072 x 2048). Sadly the P700 does not have a RAW capture mode.
Below you will find crops of the same 240 x 180 portion of the center of a sequence of images taken at some of the available combinations of image size and quality. Crops shown are at 100%, saved as extremely high quality JPEG.
The P700's JPEG Fine setting is has a very low compression which leads to pretty large files (typically over 4 MB at full resolution), this is obviously virtually lossless with no visible artifacts. Dropping down to the JPEG Normal setting we would have to search pretty hard to find artifacts, although some are visible at the JPEG Economy setting. The P700's downsampling interpolation algorithm appears to be good with clean images and very few jaggies. It's a pity Casio hasn't included a RAW format for its 'prosumer' camera.
