StylesStyles basically provide the digital photographer with the ability to "change films" to get a different look ideally suited to a specific photo situation. Canon calls these Picture Styles, Nikon calls them Picture Controls, Olympus calls them Picture Modes, Pentax calls them Custom Images, and Sony calls them Creative Styles. Basically, these provide a number of presets, such as Standard, Portrait, Landscape, Neutral, Monochrome (black-and-white) and more. You can then, if desired, fine-tune the sharpness, saturation, contrast and color tone. For monochrome images, you can apply colored-filter effects and tone the images sepia, blue and other hues. You can even create your own styles, save them and recall them when desired.
Compacts and D-SLRs Share Processors?You may notice that some compact digital cameras seem to use the same image processors as their manufacturers' D-SLRs. For example, some of Canon's newer PowerShot compact models feature the company's latest DIGIC 4 processor, as do the EOS 50D, EOS 5D Mark II and EOS Rebel T1i D-SLRs. Canon tells us that in its case, it's indeed the same processor hardware, but the programming is unique to each camera model.
In the case of other brands, the processor itself may vary from camera model to camera model. Nikon's recent digital cameras employ the company's EXPEED processing system, tailored to the needs of each specific camera model. Likewise, Sony's Bionz system used on its D-SLRs and most Cyber-shot compacts is optimized to each camera model's specific features and needs. Pentax's PRIME processing is found only in its D-SLRs. In any event, you can rest assured that each new D-SLR and compact digital camera has a processor and processing system optimized for its specific needs and users.
