The Canon PowerShot Pro 70 (referred to as the Pro70 from now onwards) is probably one of the second most desperately anticipated new routes of early 1999 along with the Sony models DSC-D700 which is seen by many as its main competing. However, people in the know like to think that this is the digital camera for the real photographer, with The canon eos excellent digital photography qualifications a audio popularity for generating top great quality products the PowerShot Pro 70 certainly comes from a good constant.
The Pro70 is different in design to other digital cameras in that it appears like a practice SLR, with a gun barrel for the lens, the zoom capability activate one part of the lens and the standard SLR-like side hold on the right-hand part this is a relaxed digital camera to hold. Although you pay for that convenience in weight, the digital camera is in at about 800g packed with one of its two provided NiMH standard rechargeable battery power. It also has other 35mm-friendly functions such as a 3:2 picture rate (same as Negatives film) and a top great quality 28mm (wide) to 70mm (zoom) lens. And some rather improvements like its turn out / rotating LCD and display hotshoe.
- Flip-out, tilt and swivel LCD is very useful in all sorts of circumstances
- Image quality is superb (possible the FINE JPEG compression could have been a little less)
- Wide angle zoom shows no barrel distortion effect
- Image ratio of 3:2 (same as 35mm film)
- Ability to take TWO CF Cards (one slot being CF+ type II)
- Supplied NiMH battery and charger / power supply
- Form factor and ergonomics are excellent, the camera feels ‘comfortable’ to use
- Very fast software / menu / startup and cycle times
Excellent build quality / lenses
- Good manual control features (aperture priority mode)
- High shutter speeds at lower resolutions (ISO 400)
In playback method the display and changing of pictures is quick and pictures appear ‘at once’ rather than gradually down the LCD. Coming into selection method gives you the following selection options. You can move from picture to picture by using the +/- control buttons, or enter 9 at a moment thumbnail method by pushing MULTI. JUMP allows you to website through pictures of 9 pictures one website at a a moment.
Continual Capturing / Rush Mode
Drive is only available in automated method (P) and when selected will force you into low quality (768×512). This also reveals up the higher ISO scores of 200 / 400. And quicker shutter rates of speed. Pressing and having down the shutter you will first pre-focus then take pictures at about 2fps for a maximum of 20 supports (10 seconds). After a little analysis in generate method, personally modify the aperture configurations and visibility modification (and in shiny light) you can achieve shutter rates of speed of 1/3000s (up to 1/8000s) which is quick enough to lock up all sorts of quick action.
Image top quality is great, with quality as-good-as if not better than the top digicam’s on the marketplace. Color stability and visibility was outstanding (if for a absence of identify measuring). You should also ‘see with your own eyes’ by using a search through the examples collection.
Canon’s way of the CCD filter
On the Pro 70 Cannon have used an solution to the typical RGBG colour narrow now they’ve used CYGM. The colored narrow which is coloured onto the top of the CCD (dyes) is colored as caved the plan, cyan, yellow-colored, natural and natural. The personal colour for each pixel is again measured in accordance with the of it’s neighbors but the criteria here is a little more complex (subtractive) than the common Bayer design.
On their (Panasonic) 1536 x 1024 digicam using The canon eos design the following is true:
- 768 x 512 p are CYAN
- 768x 512 p are YELLOW
- 768x 512 p are GREEN
- 768x 512 p are MAGENTA
Canon’s uncompressed format
Canon have also exercised a novel and innovative way to shop uncompressed pictures, you just history the actual principles of the p from the CCD and let your PC (in this situation their TWAIN driver) do the interpolation returning to a complete colour image. All the CCD RAW computer file contains is large stage value (10-bits in The canon eos case) for each 1536 x 1024 pixel instead of 24-bits for each 1536 x 1024 pixel (as in a TIFF file).
Equivalent information dimensions for a 1536 x 1024 image in ‘uncompressed’ formats:
- CCD RAW: 1.9Mb
- TIFF: 4.5Mb
Noted image relics / errors
Sometimes you did experience too much exposure (or it could be a CCD impact known as ‘binning’) against a shiny qualifications, but this impact can also be discovered on many other electronic cameras:
There was also a minor color move issue between getting a picture as JPEG and getting it as CCD RAW. This was determined by Cannon to be the truth that the CCD RAW pictures are white-balanced in the TWAIN car owner where as the JPEG pictures are white-balanced in you. This issue would probably be fixed in a later form of the TWAIN car owner.
