The combination of the benefits of Lithium-ion batteries and SELV requirements found in bi-directional DC-DC converters has led to them being specified more frequently. Lithium-ion batteries also weigh up to 75% less than their lead-acid counterparts and can be stored in any position, making integration more flexible. They are also able to handle more charge cycles than lead-acid batteries, allowing more cycles per unit and are capable of fast charging, up to 100% in 30 minutes. They also significantly increase the driving range of a vehicle, with a Lithium-ion batteries typically having capacity of 150 to 250 Wh/kg, compared with 30 to 70 Wh/kg for a lead-acid battery. A Lithium-ion battery is more efficient and can last up to 10 times longer than a lead-acid battery. Increased electrification of vehicles is also driving demand for 48V systems. It may sound counter-intuitive to add another power system to a vehicle, where space is at a premium and the weight of a car affects performance, yet adding a 48V system to an existing 12V automotive electrical system does not require a total redesign It is therefore economically feasible to store the energy required for today’s driving experience, in 48V batteries and for it to be converted to 12Vdc as and when required. Increasingly sophisticated audio systems, infotainment and onboard computer systems mean that vehicles consume more power than earlier models. Since the early 2000s, with the addition of the in-vehicle navigation systems, the electronics content in vehicles has steadily growing. It considers the contribution they make to energy-efficient, long range hybrid electric vehicles as well as efficiently manage the vehicle’s internal communication bus for infotainment and comfort settings as well as transmission systems. This article discusses the changing landscape of automotive design and the role of DC-DC converters, and bi-directional models in particular. At the end of the day, the most important people here are the clients, not us.Bi-directional DC-DC converters are ideal for both industrial and automotive applications. Nope, there is no right and wrong and you may process your images the way you want them to. And bright, positive emotion, that is how the post-processing was done to accomplish that. What I pay attention to most, is how the overall image evokes emotion: feeling of light-hearted, joy and happiness. Under bright sun, it is shaded to pale grey, In shade, surely it is darker. What is wrong with black hair? Why would you want to see that much detail i the hair? The blackness of the hair is also subjected to different lighting condition. Of course, this may not necessarily suit everyone, and as subjective as art itself, not everyone can agree with one particular style. The photographer, during the shoot and in post processing decides to achieve certain look and feel to the photograph. Look around any great award winning wedding photographs and you will see that not everyone adhere to the "strict shadow management regime", or "dipping to dark grey vignette". I also believe that post-processing techniques and style are conscious choice and decisions that photographers make.
I always appreciate feedback and I thank you for that. At times you can notice that it greys out the black hair, other times blacks it out too much. And if you fade the center, you must also fade the vignette as the blacks must respect the fading (therefore dipping to dark-grey instead of black)

Ex: if you fade the skin, don't fade the grass behind else the correlation between skin and grass would be too close for any to stand out.
Fading almost everything flattens the depth of the captured emotion. There exist a faded look but it works when there is a natural "hook" into the image to keep us in the moment of the image. I would like to first point out the pale-ness of the skintones as they appear very faded and unnatural as they are also almost devoid of any shadows that could hint at volume or 3dimentionality. Your shots are definitely on point but post-processing can improve more as you head towards the final edits :) I'm enjoying the compositions there and the 45 1.8 is really shining through. Some constructive criticism for you to improve on.
