Earlier military units like bowmen and knights needed years of practice to master the skills.

Though early muskets had less fire rate, range, accuracy and reliability than crossbows and longbows, firearms allowed essentially anyone to become an effective soldier with very little training. Continuing advances have overtaken 35 mm film and are challenging 70 mm film applications. 240 V single- or three-phase at 20-50 A for film cameras). CMOS-based cameras also require less power (single phase 110 V AC and a few amps for CMOS, vs. The advantage of rapid setup time, editing in the camera, and nearly-instantaneous review quickly eliminated 16 mm high speed film systems. When first introduced, high speed CMOS sensors were less sensitive, had lower resolution, and cameras based on them had less duration (record time). Workstations still exist, but are increasingly assembled from high-end personal computer parts, to the point that the distinction is fading Though mainframes survive in a niche market which persists to this day, minicomputers have themselves been disrupted into extinction. In the same manner, high-resolution digital video recording has replaced film stock, except for high-budget motion pictures. Cameras for classic photography are stand-alone devices. Digital cameras have a high power consumption (but several lightweight battery packs can provide enough power for thousands of pictures).

The convenience of small memory cards and portable hard drives that hold hundreds or thousands of pictures, as well as the lack of the need to develop these pictures, also helped. Quality and resolution are no longer major issues and shutter lag is much less than it used to be. Originally, instant photography, now increasingly all chemical photographyĮarly digital cameras suffered from low picture quality and resolution and long shutter lag. Nevertheless, they lowered the cost of entry to the publishing business, and economies of scale eventually enabled them to match, and then surpass, the functionality of the older dedicated publishing systems.

However, cable-operated excavators are still used in some cases, mainly for large excavations.Įliminating the need for the ice box and the milkman.īy using mostly locally available scrap and power sources these mills can be cost effective even though not large.Įarly desktop-publishing systems could not match high-end professional systems in either features or quality. Hydraulic excavators were clearly innovative at the time of introduction but they gain widespread use only decades after.
