Samsung’s new ISOCELL GN1 sensor features Tetracell tech, phase detection on all active pixels

20 May

Samsung Electronics has launched a new image sensor that is designed for use in the primary camera of high-end smartphones. Like other sensors from the the ISOCELL family, the ISOCELL GN1 comes with the company’s pixel isolation technology that creates a barrier around each pixel in order to reduce color cross-talk.

At 50MP the sensor´s native resolution is fairly moderate when compared to the 108MP juggernaut used in Samsung’s latest flagship smartphone, the Galaxy S20 Ultra, but has other tricks up its sleeve: it’s Samsung’s first image sensor to combine Dual-Pixel autofocus with the company’s Tetracell technology, allowing for increased light sensitivity in low light as well as precise and fast autofocus performance in all light conditions.

The GN1 comes with 100 million phase detection autofocus (PDAF) sites, meaning all of the sensor’s active pixels double as focus pixels, allowing for fast focusing in all light conditions and at all angles. Dual Pixel technology places two photodiodes side-by-side within a single pixel. When an image is captured the outputs from the two photodiodes are merged into a single pixel. Samsung also offers a software feature that can analyze light information from both photodiodes to compute image output that is comparable to a 100MP file.

Tetracell uses pixel-merging methods to increase light sensitivity in low light conditions. Four adjacent pixels are merged into one doubling the effective pixel size from 1.2?m to 2.4?m and quadrupling the light sensitivity at a 12.5MP output size. In bright light the sensor can operate as a standard Bayer sensor and capture full-sized 50MP images.

In addition the GN1 sensor offers a Smart-ISO function that ‘intelligently sets the optimal ISO value, and a real-time HDR mode. Electronic image stabilization uses data from the device’s built-in gyro to avoid shaky video and blurry images and video shooters can make use of an 8K video mode that can record at 30 frames per second.

Overall the GN1 looks like a very versatile image sensor that can adapt to a multitude of shooting situations. In bright light the 50MP resolution should allow for excellent detail. In dimmer conditions the Tetracell tech can deliver images with low noise and a wide dynamic range. At the same time the all-sensor Dual-Pixel autofocus system is making sure subjects are in focus, even in difficult scenes.

Samsung says mass production of the ISOCELL GN1 sensor has started this month. We’ll find out how it performs in real-life conditions once the first GN1-equipped devices make an appearance in the marketplace.

PolarPro introduces ultra-lightweight filter systems with active creators in mind

13 Nov

Today, California-based filter manufacturer, PolarPro, known for their premium ND and polarizing filters for cameras, as well as drones, announced the launch of two toolless, ultra-lightweight filter systems – one matte box, Basecamp, and one landscape filter system called Summit – designed to catapult professional creatives to the next skill level.

BaseCamp Ultra-lightweight Matte Box System

A base camp is a pillar of safety, as you head out into the unknown. It’s a haven to take shelter intermittently as battle the elements and push your limits to capture the best possible footage. Camera gear is getting heavier, especially lenses as higher quality optics are implemented. PolarPro designed BaseCamp, the lightest matte box system possible at 438 grams, to alleviate the burden heavier cameras put on operators and gimbals.

Built on the foundation of PolarPro’s Quartzline series, the toolless Variable Neutral Density configuration allows photographers and filmmakers to adapt to any lighting change instantly without having to swap out filters. Its modular design, constructed out of aluminum and carbon fibers, features a removable flag and hood that allows users to customize it to suit their production requirements.

Summit Landscape Filter System

Summit is a new range filter system aimed at photographers. It allows for toolless filter swapping and, like the BaseCamp system, has been designed with a large grip handle to minimize the risk of fingerprints on the filters. Summit filters screw onto the end of your lens and were constructed, with lightweight aluminum, in a fully light-sealed system to prevent light leakage.

PolarPro is offering $ 100 off the first 300 people who purchase their Summit Landscape Kit, the BaseCamp VND Kit, and their Cores. The BaseCamp VND Kit retails for $ 799, its Core is $ 399, Rectangular Filters are $ 299 each, while Rails Kits come out to $ 119.99 each. The Summit Landscape Kit will cost you $ 699, its Core $ 299.99, both Gradient and Neutral Density Filters $ 249.99 each, and a Circular Polarizer for either the Matte Box or Filter System costs $ 150. All can be purchased on PolarPro’s website.

Canon patent application details hybrid speedlight with active cooling via internal fan

04 Nov
The fan, labeled ‘155,’ is located on the bottom of the flash head.

A recent patent application from Canon details the schematics for a hybrid speedlight that has built-in cooling for keeping the speedlight cool with continuous use.

Japanese patent application 2019-185021 shows various ways in which a fan underneath the flash head of the speedlight would pull in air from the ambient environment, direct it over the front of the main flash tube and cycle it out to keep temperatures at a more manageable level. Interestingly, the patent also shows a pair of LED lights above and below the main flash tube, the reason we consider this a ‘hybrid’ speedlight.

Various illustrations in the patent show how the air would be channeled through the flash head depending on where the flash tube is located inside the speedlight. This particular example shows how the air would flow in front of the flash tube (and LED lights, labeled 102 and 104) and cycle out of the speedlight via the empty space behind the flash head and LED lights.

The patent doesn’t specify whether or not the cooling mechanism is more for the main flash tube or the LED lights. But, considering fans aren’t necessarily a requirement on traditional speedlights and the incredible amount of heat LEDs can put out — especially in a confined package without much passive cooling — we believe it would make the most sense that this fan would run at times when the LED lights would be on for extended periods of time, where heat could built up without the chance to dissipate in a reasonable timeframe.

As noted by Canon News, who first broke down the patent, the detailed drawings and tech specifications for this speedlight indicate that quite a bit of work has gone into it already. As with all patents, it might never see the light of day, but it’s an interesting concept nonetheless.

Instagram reaches 1 billion active users

22 Jun

With its stand-alone IGTV video app Instagram had a big product announcement this week, but at the launch event in San Francisco the company had another milestone to talk about: after surpassing 800 million active users last September, Instagram has now reached the 1 billion mark.

After Messenger (1.3 billion), Whatsapp (1.5 billion) and Facebook itself (2.2 billion), this makes the mobile image sharing platform the fourth Facebook-owned social media app to reach this lofty number. When Instagram was taken over by Facebook in 2012, it had approximately 40 million users. The app’s massive growth makes the 1 billion dollar price tag back then look like a very sound investment now.

It also shows that the recent privacy controversies around Facebook after the misuse of data belonging to 50 million of its users don’t appear to have a lasting impact on the company’s apps’ and services’ user numbers.

DIY Camera Bag Modifications for DSLR Storage and an Active Lifestyle

03 Jun

In today’s world, digital camera technology continues to improve and get lighter. A plethora of systems offer lighter camera bodies with more technology bundled into them. There are many photographers transitioning to these systems to lighten their gear and are selling off their old equipment. However, I cannot help but be attached to the reliability and familiarity of my full frame DSLR bodies.

I do not like to compromise on image quality and feel most confident making quality images in spur-of-the-moment wildlife activity or in difficult lighting with my full-frame camera. Are you the same as me? If so, does that make us a little crazy?

Pelican case - DIY Camera Bag Modifications for DSLR Storage and an Active Lifestyle

The Pelican case gives me space for a couple of bodies, a 200-500 mm telephoto lens, and two shorter ones. Lots of space to pack a full kit!

Well, in truth, it is a bit crazier than that, I am most comfortable when I have two camera bodies with me at all times. I also carry a telephoto lens, 50mm, and wide-angle lens with me along with cleaning equipment and filters, and I like to do so at all times. In other words, I carry a full kit. I do my best to carry a full kit when hiking 10 miles into the backcountry, floating a 5-mile river trip, or walking to a local beach to watch a sunset.

If you are like me you are constantly looking for ways to safely haul your gear from Point A to Point B while also protecting your investment during your adventures. Through experimenting and modifying a Pelican 1510 case I have found a solution that works for me. In this article, I will demonstrate that system for you. I hope my DIY camera bag for DSLR storage and transportation works for you and inspires you to get more creative in hauling your gear!

DIY Camera Bag Modifications for DSLR Storage and an Active Lifestyle

I customized this Pelican 1510 case to provide waterproof and shockproof protection for my DSLR bodies and kit. Thanks to the modifications I have made, I now transport this kit everywhere.

What you’ll need

  1. A hard case – I use a Pelican 1510. The case is TSA approved as a carry-on size, meaning you’ll never have to check your camera gear to baggage claim. I pack non-critical, lower-cost items in the modular pack (see below in #4) and check those in my bag. Then I carry on the rest of my kit.
  2. A drill, 3/32 drill bit, and 3/8 drill bit – You’ll need a high-speed drill and a sharp bit to do some customization of the Pelican case. Make sure the 3/32 bit is wide enough diameter to put the eyebolt through.
  3. Eyebolts (2x) with nylon locking nuts (2x) – These will be used to secure the luggage straps to the Pelican case in the front.
  4. A secondary “modular” case for the outside – You can choose any case that is the same size or smaller than the Pelican case. Think about the gear you are using and tailor it to fit your needs. I make sure my modular case can hold my filter set, cleaning equipment, batteries, and other photography knick-knacks.
  5. Velcro – This will be used to secure the secondary modular case to the outside of the Pelican case. Get Velcro strapping that has sticky sides.
  6. Adjustable luggage straps (2x) – make sure the straps have good clips. I prefer a 1” wide webbing for the strap.
  7. Carabiner clips (2x) – These will be used to secure the luggage straps to the Pelican case in the back.
  8. Backpack straps – I use the Pelican 1510 backpack conversion straps offered by RUCPAC. I have been using their system for about two years now and find it durable and comfortable. If you are a true DIY-er you could modify the straps of an old backpack.

Modifying the Pelican 1510 Case

Pelican 1510, DSLR Storage, Camera, Modification

Step #1 – Drill holes near the latches

Close the lid and use the 3/32 bit to drill through the plastic to the inside of each latch. You’ll need to go through both layers so the extra length of eyebolt has a hole to pass into. Once you have drilled the hole, open the case and use the 3/8 bit to bore into the plastic so that the nylon nut recesses into the case and allows it to close. Repeat on both sides of the case.

You can see here that I bored through both sides of the Pelican case with the 3/32 bit to allow the eyebolt to pass through. I bored with the 3/8 bit into the top layer to allow the nut to recess so that the top can close

Step #2 – Drill holes through the fins (back hinge)

Use the 3/32 bit to drill through the “fin” on the backside and pass a carabiner through the hole. The fins are the rigid plastic ribs that stick out to hinge the lid and bottom of the Pelican case together.

Repeat on the other side.

I drilled through the “fin” of the back with the 3/32 bit and threaded the carabiner through. I did the same thing to the other side of the pack.

Step #3 – Apply the Velcro

Apply the Velcro to the back of the modular case and then line it up accordingly on the front of the Pelican case.

Tip: Stick the hook side and the fuzzy side of the Velcro together on your modular case, peel the paper off to expose the sticky surface and then press the modular case onto the Pelican case to get a perfect alignment of your Velcro.

Attach Velcro to the top of the Pelican case and make sure that it aligns with the modular case. It is easies to make sure that the Velcro is aligned by sticking it together, applying it to the Pelican case, and then pressing the secondary modular case onto it.

DIY Camera Bag Modifications for DSLR Storage and an Active Lifestyle

Attach the Velcro.

With the Velcro attached to the Pelican case and the modular case, you’ll be able to open and access the case without it falling off the larger Pelican case. That’s a huge perk!

Step #4 – Thread the luggage straps onto the system

Thread the luggage straps through the eyebolt and the carabiner. Adjust it to a length that fits around the modular case, and then tie a good knot – I prefer two half-hitches.

DIY Camera Bag Modifications for DSLR Storage and an Active Lifestyle

Make sure the luggage straps are long enough to wrap around the modular case. Tie the ends securely to the carabiner and eyebolts.

Step #5 – Install the backpack straps to the Pelican case

Next, install the RUCPAC straps to the Pelican case. This is very simple – you’ll attach it to the top handle and thread the straps through the bottom wheels. Instructions to install the RUCPAC come with the product.

There you have it!

This DIY camera bag solution has grown with me and my kit and worked for me the last two years. I find this pack very comfortable to use and wear. I am 6’3” and would be interested to hear if it fits shorter torsos as well.

The luggage straps give you the flexibility to attach a tripod or any other gear on to the outside. You can choose the size of modular case you that use to accommodate the gear you have.

This pack also provides a portable chair for those long days or nights shooting photography and can act as a tripod in a pinch. In fact, having the pack available has saved my shoot on several occasions when I needed stabilization but did not have a tripod.

DIY Camera Bag Modifications for DSLR Storage and an Active Lifestyle

The DIY camera bag case can function as a spur-of-the-moment tripod. I’ve used it for shooting the Northern Lights and time-lapses.

I took this image of the Aurora Borealis with my camera stabilized on my Pelican case. It saved the night since I did not have a tripod along with me!

Conclusion

What I’ve shown you here could be just a jumping off point for you. Use this concept to expand and create your own DIY storage solution that works for the gear and kit you have, and your needs.

Once you are done get out there and shoot lots of images. As I like to say, “pixels are cheap”, so go make a lot of them!

Open source Lightroom plugin Focus Point Viewer highlights active focus points

05 Jan

Joshua Musselwhite, an underwater photographer and software developer, has launched a free, open source Adobe Lightroom plugin called Focus Point Viewer. With this plugin, Lightroom users can view the active focus point of their photos, a feature similar to the one offered by now-defunct plugin Show Focus Points. 

Musselwhite details his new software on Reddit’s photography subreddit, where he explains that Focus Point Viewer was created as a way to easily see whether the focus points in his underwater images were the ones he had intended to use. The software is currently only mapped for his camera, a Nikon D7200, but because it is made freely available anyone can take the time to map the plugin to their own camera.

Explaining how to perform the mapping, Musselwhite said:

You’ll need to map each of the focus points. The best way I knew how to was take 51 photos at each focus point and determine the x,y pixel location for each from the top left using photoshop. I searched and searched for a focus point map for my camera but couldn’t find any … The process is a little time consuming, but it only takes a couple of hours, and is described how in the README file in Github.

The Github README file with the full explanation can be viewed here, and the entire project is available here. Musselwhite has also shared a small gallery showing both the focus points in action and the metadata submenu.

Samsung announces ruggedized Galaxy S7 Active

06 Jun

Samsung has announced a ruggedized “Active” version of the standard Galaxy S7.  The Active comes with the same IP68 rating for water resistance as the standard device, but adds the MIL STD-810G standard and a shatterproof display to the mix, making the S7 Active resistant to the occasional drop. 

The beefy 4000 mAh battery is another notable change compared to the standard S7’s 3000 mAh variant but most other internal components remain unchanged. Like on the Galaxy S7 the Android OS is powered by a Qualcomm Snapdragon 820 chipset and 4GB of RAM. Versions with 32 or 64GB of internal storage are available and a microSD-card can add up to another 256GB. For added security a fingerprint reader is on board and, important for mobile photographers, there are no are no changes in the camera department either.

Images are captured on a 1/2.6″ 12MP sensor with 1.4 µm pixel size and on-sensor phase detection. The aperture is a very fast F1.7 and the focal length 26mm equivalent. The camera is capable of recording 4K video and at the front a 5MP/F1.7 module should be capable of capturing decent self-portraits.

At least for now the Galaxy S7 is exclusive to AT&T in the US. It will be available from June 10 and cost you $ 26.50 or $ 33.31 a month, depending on your plan. The Galaxy S7 Active looks like a good options for those who like shooting with their phone during outdoor activities and the like, let’s hope Samsung will make it available through additional channels sometime in the nearer future.

Video Rating: 0 / 5

dombowerphoto.blogspot.com as you change your Q scale settings from -16 (highest quality) to -1 you lower the bit rate of the video, meaning you get more video time, but lower quality video, at -16 my memory card cant keep up for more than 1 second, around -9 my card can do fine but if i am doing a long video i feel it is ok to go to -6 on the q scale. going to Postive 16 it is just a mess, it is only about 1mb a second speed, very very slow and very poor quality. This was shot on the canon 550d with firmware 0.2.0 as of March 22nd 2011
