4. DPI and PPI are synonymous.

DPI stands for dots per inch which is the resolution in prints while PPI stands for pixels per inch which is the resolution of the file. DPI then is the number of dots the inkjet can make on the surface of the paper. PPI is the number of pixels found in every inch of the image in terms of the height and width of the image.

5. The file format is JPEG.

This is not the official format. There are the TIFF and RAW. The file format is contingent on the purpose of the file. For internet use such as emails, JPEG is ideal because of its ability to compress the file, making it smaller and easier to send. For images that need to be enlarged, the RAW format is ideal. Most of the digital master photos use the TIFF format.

6. Blurry photos can be eliminated by the UnSharp Mask (USM).

The sharpness of the image can only be retained. Once the photos are blurred, this may due to your shaky hands while taking the picture. Blurred will remain blurred and will not be reversed by the USM.

7. Printing is more convenient than traditional laboratories.

Digital printing is faster but the processes are more complex. Producing digital fine prints entails more experienced and skilled technical people to control tedious. Many experienced conventional darkroom experts who are now in the digital darkroom can attest to this fact.

8. Digital cameras with bigger pixels perform well.

What is true is that larger pixels produce larger pictures. Performance-wise though, it is not true. The quality depends on the skills of the photographer and abilities to achieve the desired effect. Pixels are not all that matter.

9. Effective focal lengths can be increased.

Effective focal lengths are achieved by the size of the image sensor. There is a disparity between the projection of the image by the lens and the recording of the image by the digital SLR, leading to the impression that the DSLR has increased the focal lengths.

10. Calibrating the hardware once is enough.

You need to recalibrate your hardware to maintain its effectiveness and productivity.
