Convert images in Black & White

Most of us love black & white pictures, they are part of our memories and an artistic expression. How can we transform the pictures from our digital camera to B&W?
The first and quickest way is to set our camera in B&W mode, this is quick, this works but has a very important down side, it is difficult to add the colours later on.
My opinion is to have the chance to choose the best between two different kind of pictures instead to have just one of them.






The other more effective way is to use one of the many photo editing software (GIMP, Photoshop, Elements...) to change the "Saturation" value to "-100" (zero -  this value is related to the software in use).
Please find an example below.

Once the "Saturation" has been set then we can change other parameters such as "Exposure", "Temperature", "Tint" and "Contrast", accordingly with the actual image and our personal taste.

For example, moving the "Tint" cursor/value from one side to the other we will notice how the density of the image increase or decrease.

Please find below the final result of the above example:

Sony Smartphone Lenses - QX10 & QX100


Sony QX100 lens turns your smartphone into a professional DSLR
QX100 lens turns your smartphone into a professional DSLR
When I first read about something new from Sony I was honestly very skeptical, it is because the last few years of Sony products and marketing. In the last ten years Sony has been able to lost the leadership in all the main markets and technologies (except maybe for the game consoles, PlayStation). This time instead Sony come up with something really innovative and appealing.
Bluetooth lenses that we can use plugged to our smartphones, Android or Apple, or remotely using the Bluetooth or NFC technologies to pair them  our devices.



These lenses, the QX10 and the QX100, have been  presented during IFA electronics fair in Berlin and the details are as following:

QX10 = f/2.3-5.9 lens and 18 megapixel sensor - probable cost about £180.00
QX100 = f/1.8-4.9 Carl Zeiss lens and 20.2 megapixel sensor - probable cost about £400.00

The comfortable use of this portable lens can really change the photography vision and way to take pictures, especially for old people like me used to move around a studio with an heavy 6X6 Pentax. Using these lenses remotely will be possible to explore new angles and possibilities. Creativity will be more free to express itself and probably we will be able to plug those lenses to our laptops/tablets/PCs too.







I add to the article this short but enjoyable video from Sony. The video shows as comfortable and easy could be to take high quality images in any circumstances.
