Windows Server 2012 is doing the same as most modern software - it is losing features. Sometimes that is a good thing - losing fat is good, spring cleaning your home is good... Trimming the fat from bloated software is definitely a good thing. What is NOT acceptable in my mind, is removing crucial functionality under the disguise of an upgrade / improvement.
I can think of many examples:
- Microsoft Edge threw away 90% of the IE11 browser's capability (many of these were good choices, some not)
- All the Windows Metro apps that basically contains no functionality other than core features, that were intended to replace their desktop counterparts.
- Mac OS X Disk Utility that lost many of its abilities just to look cool and be simpler to use.
- Mac OS X Photos app that is not even remotely related to Aperture, citing simplified user interface but basically losing 99% of its functionality.
- Online cloud based apps such as QuickBooks, that cannot do half of what the desktop application can do.
- The list goes on.
A specific example I want to touch base on is Windows Server 2012 R2 that cannot show you the IP address of an RDS session any longer. You used to be able to right click on an RDS session in Remote Desktop Services Manager, select Status and see the IP address and client name of the connected session. No such feature exists any longer in Windows Server 2012 R2. Not even going to PowerShell and executingRead More...
The image above has, like many photos, a story behind it. Often non-photographers look at photos and do not understand what went into the making of a good photo. When working with the microscope, things are even more alien as there is a bunch of additional considerations that need to be taken into account before you can even begin turning on the camera.
Lets start at the beginning. Not all good photographs can be had at first attempt. Sometimes you have to fail (many times) before you can succeed. Here is the best I could do 4 years ago:Read More...
There are more arguments about photo editing and processing than there are photos in this world. Ok, that might be a slight exaggeration. But still, it is an argument that has become especially prominent with the rise of digital photography due to the easy manipulatability of photographs.
Some people believe you can do whatever you want to a photo, it is all about art. At the opposite side of the spectrum are the purists - who believe that the only changes you are allowed to make are basic exposure, white balance and sharpening. I am more specific in my beliefs.
If you ask me this question, I would say that it depends on the purpose of the photograph. If it is to document something formally like a crime scene, biology, photojournalism etc., then it is paramount that any adjustments be limited to those that improve the quality of the image and improve the correlation between it and the real world. Take note that I did NOT say it should be limited to basic exposure. My reasoning can be understood by realising that when you press the shutter button on any camera, especially a digital camera, before that image is stored on the memory card it had undergone a huge amount of processing. Some of these processing steps are:
Light wave are being bent by the optics in the lens, and colour casts are introduced and other optical aberrations such as chromatic aberrations, vignetting, distortion etc. No lens is perfect.
These photons pass through an IR filter which removes IR wavelengths.
Most cameras have a low pass filter to slightly soften the image so as to reduce the chance for moiré. This destroys some fine detail.
The light wave is further bent via micro lenses that sit in front of each photo site on the camera sensor.
Once the photos hit the CMOS sensor, they cause an electric charge to build up. This charge contains background noise levels from quantum effects, distorting the signal and introducing noise.
Depending on the CMOS sensor, reading the electric charges in each photo site will necessarily introduce some additional noise and signal alteration.
Once the electrical values for each photo site has been read, it is sent to an ADC (Analogue to Digital Converter) and various other electric components to ultimately end up in the RAM / CPU of the camera. All these steps alter the original signal by making approximations and conversions via sampling and other processes.
Once in the CPU / RAM, the camera then performs various calculations and processing to form a final RAW image that is recorded on the memory card. During these processes some additional signal alteration occurs.
When you download the image to your computer and open it up in your RAW converter, a huge amount of basic, default processing occurs. Most significantly are demosaicing and applying of tone curves and colour profiles. These steps cannot be changed or avoided, and each RAW converter adds its own signature look to the images as they all convert the data differently.
