RICOH Launches PENTAX K-1 Mark II, An Entry Level Full Frame Digital SLR Camera :

A successor to the PENTAX K-1 full-frame DSLR camera launched way back April 2016, on 21st FEB 2018 Imaging Corporation RICOH Launches PENTAX K-1 Mark II Entry level Full Frame Digital SLR Camera. Its compact, rugged and weather-resistant, dust-resistant (as most of the times). PENTAX K-1 Mark II now becomes one of the high end camera from home of Pentax. This is a upgrade so one can expect some newest of technologies inside this new beast. This can help in delivering a better and outstanding image quality along with broader range of shooting condition because weather shield and its revolutionary Pixel Shift Resolution System II.

An Upgrade to Ricoh’s Pixel Shift Resolution System I :

One of the most exciting feature of Mark II is Ricoh’s Pixel Shift Resolution System II. This was first introduced in Pentax K-1 and was really exciting as this was the first time anything like this was introducing to a camera. With the Pixel Shift Resolution System II, the camera also obtains RGB color data, resulting in images with significantly finer details and truer colors than those produced by typical full-frame sensors. A quick turn back to Pixel Shift technology is. In simple terms, if you shooting handheld then the camera will remove any shake from the picture by taking multiple exposure shots and then creating one final image without any blur or shake. Suppose you are shooting a building and some bird flies across then you wont see any bird in the final picture. PST (Pixel Shift technology) will remove the movement from the picture and you will get sharp image without the need of a tripod.

Low Light Performance :

Another specification is, PENTAX K-1 Mark II equipped with full-frame Anti-aliasing CMOS sensor with 36.4 megapixels as its predecessor model. But, Ricoh has added a new accelerator unit to the PENTAX K-1 Mark II that—along with the camera’s PRIME IV image processor—enables it to produce high-resolution images with minimal noise in even in the most challenging low-light conditions, up to ISO 819200. This makes the new camera ideal for low-light photography where higher shutter speeds are required.

Some additional and impressive futures includes a sturdy anti dust magnesium-alloy body with weather-resistant construction; an optical viewfinder with a nearly 100-percent field of view for real-time subject confirmation; Astro Tracer, which simplifies the tracing and photographing of cosmic objects like stars and galaxies by coupling GPS data with the camera’s sophisticated SRII mechanism; and a flexible tilt-type LCD monitor to accommodate various shooting angles.

Pricing and Availability :

The Pentax K-1 Mark II suggested price will be around £1,850 and could be launched in Mar end or April 2018.

NOKIA 8 Pro With Rotating Penta Carl Zeiss Lens – A Real Game Changer

Nokia 8 Penta lens

If the rumors to be believed, HMD Global or Nokia will be launching Nokia 8 pro version by the last quarter of 2018 which could be embedded with five lenses, yes you heard it right. This could be first android phone equipped with Penta Lens. So lets see how’s NOKIA 8 Pro With Rotating Penta Carl Zeiss Lens – A Real Game Changer.

Leaked Images from Chinese Social Media

If dual lenses or quad lenses from Honor was not enough, you must be wondering what would they do with five lenses. Is it a gimmick or does have some purpose in real life ? lets find it what rumors says.

NOKIA 8 Pro With Rotating Penta Carl Zeiss Lens :

The most exciting feature of the phone as per the rumors will be its 5, ye five Carl Zeiss cameras at the back which could  be rotating. This device could feature a rotating element with housing all 5 lenses and LED flashes at the rear, which would probably have varying focal lengths and apertures. Different focal length and aperture will keep this phone flexible for tons of specific shooting situations like a lossless zoom with telephoto version or a better low light performance with wide and big aperture.

NOKIA 8 Pro With Rotating Penta Carl Zeiss Lens - A Real Game Changer

Other possible specifications are, 18:9 display with minimum bezels and a 3D double-glass design with Qualcomm Snapdragon 845, but nothing will probably be able to top that Penta-lens camera.

Its like the first true mechanical optical zoom camera in a smartphone, one which will rotate various zoom lenses in front of same main camera sensor.

So a single sensor will do job for all five lenses. Looks interesting and damn exciting too.. right.

Conclusion :

Nokia has quite a few rumored devices already in queue in the making so there’s no way of knowing is this Nokia 8 Pro is real or not, but if the company really wants to continue its upward momentum, the time is nigh for it to truly innovate. The penta-lens Nokia 8 Pro could just be that.

This Penta-lens theory may well be a no-compromise solution for lossless zoom or low light photography, and would also go some way closer to minimize the gap between smartphone cameras and traditional cameras with changeable lenses.

Understanding Histograms Statistics : How to Read A Histogram in Lightroom

HIstgram_banner_pixelrajeev

Histogram is quick way to analyze exposure in photography. It helps us to understand how much details each image has preserved. Pixel details should not loose because of dark shadows or due to too much highlight in photograph. In this article we will be Understanding Histograms Statistics and How to Read A Histogram in Lightroom with example. 

What is Histogram :

Now a days histogram can be found in almost every camera and image editing software. Some camera allows a live view as well if you shoot through LCD. Histogram has become very important and helpful to understand in how much details each part of image carries. Many photographers do find it difficult to read in start, I agree it looks very complicated with up n down vertical bars but believe me its very easy to understand and quite helpful too. Here in this blog we will try Understanding Histograms Statistics in Photography. 

A histogram is a graphical representation of the tonal values of your image. In other words, it shows the amount of tones of particular brightness found in your photograph ranging from black (0% brightness) to white (100% brightness). The middle portion of the histogram represents mid-tones, which are neither dark nor light. Vertical axis of a histogram displays the amount of tones of that particular lightness. 

Understanding Histograms Statistics :

The left side of the graph represents the blacks or shadows, the right side represents the highlights or bright areas and the middle section is mid-tones. histogram_mainHow high the peaks reach represent the number of pixels in that particular tone. Each tone from 0-255 (o being black and 255 being white) is one pixel wide on the graph, so imagine the histogram as a bar graph all squished together with no spaces between each bar.

Gaps on either end indicates you are missing information and your exposure can be shifted safely without losing detail.

You also have to remember, if there is a sun in your image then obviously it would be very bright and white and in this part of the image due to this highlight you could loose some details around this portion of image.

Histogram and Exposure : How to Read A Histogram in Lightroom

Underexposure:

This is a underexposed image (very dark) where you can hardly see any details. If you check here (top right side) in histogram, it clearly shows a strong shift to left side which means most of image is in shadows and completely black.

Histogram_underexposed , pixelrajeev

Overexposed:

This is a overexposed image (too much light) where many tones are very bright with almost no dark tones in pictures. Due to too much light almost entire image is blown-out and lacks details. Check histogram here, it clearly shows a strong shift to right side, which means most of image is too bright and blown-out (completely white and bright). 

Histogram_Overexposed, pixelrajeev

Correct Exposure:

Lets analyze histogram here, there is no vertical bars on either side of histogram, which means there is no detail lost in shadows or there is no part of image which has been blown out because of too much brightness. If you see closely, histogram spikes up on the portion of image where parrot is placed. This part of histogram showing the tones of parrot, it is properly exposed and has enough details too.

Histogram_correctlyexposed , pixelrajeev

Breaking the Rule :

What about this image? Is it underexposed ? very dark with no details.. Right ? Here Histogram also tells us that super strong shift to the left side which means image is in shadow and lack details.

Would you try to correct it ? Off course NO. The truth is histogram can not be evaluated on the basis of exposure. The correct histogram depends on many factors. Histogram merely shows you the amount of tones of various brightness levels in your image, and nothing more. It can be used to discover whether you have chopped any highlight or shadow detail at specific exposure settings. 

Histogram_breaking_rule

Conclusion :

Many photographers makes a good habit  of seeing histogram after click just to make sure nothing on the extreme right or left. Well, this habit is not going to make you a good photographer and you should also have enough time to look through LCD and analyze histogram. However, you should know how to read histogram which is helpful and invaluable in some situation at times.

Hopefully, this article helped you to understand what histograms is all about and how to read it.

My Visit :

It was a early morning on 22 Jan 2018, hard time for me finding this bird Sanctuary as the main gate was closed and there was new gate from opposite side of this sanctuary was opened, I was not aware of this 🙂 . Somehow I reached this place by 09:45 AM. There was no parking inside sanctuary, so I had to park my bike outside gate. There were few bikes already there so no issue and It was on main road almost so nothing to be worried.

I had my Nikon D3300 + Tamron 70-300 VC USD lens with me. I know 300mm is not enough for birding, but as I am not a professional so it was ok for me ( Its a costly hobby, can not afford dedicated lenses for each genre 😛 ). As soon as you enter inside you could see a lake with many different specifies of birds flying in and around. I switched my camera ON and started clicking pictures.

Here are few of the pictures which I likes most, I hope you will like it :

Xiaomi Redmi Note 5 and Xiaomi Redmi Note 5 Pro Specification and Price

xiaomi redmi note 5 and Redmi note 5 pro, pixelrajeev

So finally the wait is over for the Xiaomi fans who kept holding themselves since almost 4-6 months for the next Redmi series phone after Redmi Note 4. At an event in Delhi today (14-Feb-2017), Xiaomi Redmi Note 5 and Xiaomi Redmi Note 5 Pro Launched in India. Along with this Xiaomi has also Introduces its First LED TV in India, but for now we are only going to talk about Xiaomi Redmi Note 5 Pro Specification and its prices.

Redmi Note 5 :

The Redmi Note 5 shares the same hardware as its predecessor, with the main difference being the 18:9 5.99″ FHD+ (2160 x 1080) display at the front. Back is almost identical to Note 4 which feels little bored.

With tall display you will get same Snapdragon 635 chipset bundled with Adreno 506 GPU supporting with 3gb/4gb of ram. It has got 12MP (f/2.2) snapper with dual tone-dual LED flash and PDAF and in front it has 5MP (f/2.0) with selfie flash, Beautify 3.0, selfie timer, and face recognition (will be updated via OTA in March 2018). The phone will launch with Nougat out of the box. You would not get Oreo out of box. By this time a new phone with Nougat will be a sheer disappointment.

On the battery side, it comes with huge battery of 4000mAh with normal 5V/2A USB charging (no official fast charging). Headphone jack is still there, which is not a surprise in the budget segment.

the Redmi Note 5 is slotting in at the same price bracket as the Redmi Note 4, with the 3GB version offering 32GB of storage retailing for ₹9,999 and the 4GB model with 64GB of storage available for ₹11,999.

Xiaomi Redmi Note 5 Pro Specification :

As far as design is concerned, Redmi note 5 Pro is quite similar to Redmi Note 5 from front. From  back side it is inspired by vertical dual camera setup of IPhoneX which look better than Note 5 if not best. The biggest highlight in this phone is :

Qualcomm’s latest mid-range chip Snapdragon 636

Xiaomi Redmi Note 5 Pro Specification

Redmi Note 5 would be the first phone in the word with this newest chip from Snapdragon. The Snapdragon 636 is fabricated on the 14nm process, and features eight custom Kryo 260 cores, based on four Cortex A53 cores for efficiency and four Cortex A73 cores for performance. The chipset also features the Qualcomm Spectra 160 image signal processor (ISP), which handles the heavy lifting for the camera.

Dual camera setup:

The phone features a dual-camera setup at the rear, with a 12-megapixel primary sensor and a 5-megapixel secondary sensor. The camera setup is vertically placed inspired by IPhone X and uses an RGB setup on both sensors. The phone also features a 20-megapixel front camera with lamp flash. The Xiaomi Redmi Note 5 Pro uses software algorithms to create portrait mode shots from the front camera as well, allowing for selfies with the background-blur effect.

The phone will be sold in two variants: a model with 4GB of RAM and 64GB of storage for ₹13,999, and another variant with 6GB of RAM and 64GB of internal storage for ₹16,999.

Conclusion :

For me, Redmi Note 5 is not a real upgrade over Redmi Note 4. Just a 18:9 display is not adding much to it, yes the price is quite competitive so if this is your first Redmi phone then you can go for it. Its a good grab in budget but not for upgrade. Here, Company didn’t tried to improve the performance either and in camera department we all know Xiaomi is just OK. So if you already have Note 4, better go for Redmi Note 5 Pro rather with Dual camera equipped with SONY sensor and a better snapdragon processor adds some value to this Pro model.
