Magic Of Adobe Lightroom

March 15, 2019 in Post Processing

When I started my journey in digital photography ten years ago, I didn't have much interest in post processing. I was more focused on learning photography techniques, know more about the camera controls and the settings and get familiar with the gears, lights and other accessories. As I started gaining more experience with the camera setup and the gears, I felt more comfortable with the technical aspects of the shooting. Slowly, I started learning about the composition technique and used my technical skills to capture the image on various situations. The more I shoot, the more I felt that the camera was not able to capture all the colors I see through the lens. This is when I started to explore the possibility of introducing post-processing tool in my digital photography career. When I was shopping around for my first full frame but third DSLR, Nikon D700, I got introduced to Nikon’s own post-processing tool, Capture NX2, and without putting too much thought into it, I started using it. Since it was my first experience with any kind of post-processing tool, there was a steep learning curve for me but I enjoyed the process. After I started using Capture NX2 for a while, I felt like I was missing a big part of digital photography by overlooking the editing process in my early days of photography. Within a couple of months of using the software, I realized that, when post-processing is applied carefully and skillfully, it can completely change the look and feel of the picture and make it more alive again. But, suddenly, when I was just getting the hang of it, Nikon decided to discontinue the Capture NX2 software and stopped releasing the future updates and the support for the new cameras. I was still able to use the software (to process RAW files from my D700) for a couple of years even after their announcement but it became completely useless when I upgraded my D700 to D810 in 2017.

I had no choice but look for the alternatives which would support the RAW files from the Nikon D810. After doing much research, I decided to go with Adobe Lightroom. It's been little over a year since I started using the Lightroom and I couldn't be more happier. It is lightweight and very powerful program which works well with the varieties of RAW files. When I download the pictures on the computer, I import the RAW (NEF format) files directly into the Lightroom library and edit them when I want to. Besides Lightroom, I don't use any other tool to process my pictures. In terms of editing the picture, what I can do with the Lightroom, I could also do with the Capture NX2 but the process was complex and time consuming. In my experience, I found Lightroom to be much faster compared to the Capture NX2 and provides various powerful tools to edit the pictures with much more ease than it’s competitors. All of the edits done inside the Lightroom are non-destructible, which means Lightroom doesn't modify the original RAW file but only adds the instructions on the file based on what settings were applied during the development of the picture and renders the image by layering up those instructions step by step. You can always go back to the previous steps and undo the changes you made in those steps. However, Lightroom being a linear program, what you can not do is; you can not undo or erase one particular step in the middle and keep rest of the edits intact. For example, after applying 10 steps of editing (changing any one setting is one step of editing), you can’t undo only the 7th step and preserve the changes made in 8th, 9th and 10th steps. If you do so, it will delete everything from the 7th step up-to the 10th step and you have to progress the future editing from the 7th step again.

The New York City!

March 08, 2019 in Travel

Living in Washington DC, only four hours drive from New York City, I have been lucky enough to be able to visit this incredible city many times in the last ten years. It is always crowded, busy and messy but still magical. It hosts people from all around the world and serves food from all continents. I read somewhere that, in the New York City, even if someone eats two meals a day in a different restaurant everyday, they wouldn't be able to taste all the restaurants in their lifetime. That says so much about the magnitude of this world's largest city which has so much to offer to everyone. You can possible buy everything that money can buy here. After all, this is the Financial Capital of the free world.

This majestic city is the home for almost 10 Million New Yorkers and travel destination for almost 60 Million tourists every year. No matter what day of the month or what month of the year it is, the crowd doesn't seem to be lessening. People are out and about even if it's blazing hot outside or freezing cold. This city of concrete jungle welcomes you with the magnificent view of countless skyscrapers which seem to be growing in numbers every day. One does not have to be an architect or a photographer to admire the skyline of New York City. When I visited this city for the first time in 2009, I drove through New Jersey Turnpike and reached to the city via Lincoln Tunnel. When I saw the glimpse of these skyscrapers for the first time (from a distance), I was in complete awe and forgot to take a photo. I went there for the July 4th weekend to celebrate America's independence day and witnessed one of the biggest fireworks in the world. Even though I had just started learning about photography, I took my camera with me but didn’t feel ready to go out and shoot. I returned with some casual shots of friends and family gathering and promised myself to come back more prepared. I visited the city many times ever since and had managed to take few shots here and there. However, I was not satisfied with the outcomes and felt something was still missing. I decided to visit the city again and this time, I went back fully prepared to capture NYC in its full glory. This time, I was determined to get the shots I have always wanted and from as many places as I could pinpoint.

Autofocus Is Not Working On My Nikon D5100

March 01, 2019 in Q & A

This post is a part of our Q&A section. If you want to submit your question, please use the form in the Contact page.

Mark (New Jersey, USA) asked: I have a Nikon D5100 and recently bought a Nikon 70-300mm f/4-5.6G lens with AF but it is not auto-focusing. Am I missing some settings or something is wrong with my camera or the lens?

Hello Mark! Nikon's Autofocus system works by utilizing the motor (to move the lens elements) either inside the lens or inside the camera body. Unfortunately, neither your camera body nor the lens is equipped with such motor. Your lens might be capable of autofocus but the lens elements should be driven by some mechanism to "autofocus" and that is what missing in your combination. In short, the minimum requirement for Autofocus to work is, either the lens or the camera body has to have a focus motor. Lets discuss both of these scenarios one by one.

First scenario: Lens is AF and the camera body has a built-in motor for Autofocus.

The lens you bought is AF lens which stands for Autofocus but it will only autofocus if your camera has a built-in motor inside the camera body. All full frame (FX body) Nikon DSLRs as well as some high end crop sensor (DX body) DSLRs have a built-in AF motor which drives the Autofocus system. Among Nikon DX format (also known as APS-C image sensor format) bodies, D90 and all D7000 series come with the built-in motor inside the camera body but D60, D3000 series and D5000 series do not come with the motor. In case of such consumer DSLRs that do not come with the built-in focus motor, they need to use an AF-S or AF-P Nikkor lens to get the full Autofocus capabilities from the lens itself which we will discuss in our second scenario.

When you attach an AF lens with the camera that has a built-in motor in it, the mechanical coupling between the camera body and the lens is formed by utilizing the screw in the motor and the several pins on the lens (which is connected to the focus ring). When you try to autofocus by pressing the shutter release button half way down, camera uses multiple focus sensors to determine which part of the subject is in focus and which part is not and turns the motor accordingly to adjust the focus. These AF lenses come with their own CPU which gives the focal length, aperture setting and other information to the camera CPU which allows the camera to adjust TTL (Through The Lens) Metering for different shooting modes.

Nikon D810 Focusing Modes (Click the picture above to read my initial experience with Nikon D810)

If you want to manually focus while using an AF lens, you have to switch the lever on the camera body (box 1 in the picture above) from AF to M which then disengage the mechanical coupling between the motor and the lens so that you can freely move the lens focusing ring to adjust the focus. In this situation, camera still gets the TTL Metering and different shooting modes data through the lens CPU.

Tip : The DSLR camera bodies that feature a focus motor can use both AF and AF-S or AF-P lenses for Autofocus.

Second scenario: Lens is AF-S or AF-P and the camera body doesn't have a built-in motor for Autofocus.

Nikon's another type of Autofocus lens is called AF-S lens (not to be confused with AF-S focusing mode) which has an Autofocus motor built inside the lens. Those Nikkor AF-S lenses feature Nikon's Silent Wave Motor (SWM) which converts "traveling waves" into rotational energy to focus the optics, according to the Nikon. This enables high-speed auto-focusing extremely accurate and super quiet. You can use Nikon’s AF-S lens with any current Nikon’s camera body whether the body has a focus motor or not, because the lens itself has a built-in focusing motor which controls the focusing function based on the information it gets from the camera’s focusing sensors.

Nikon's third type of Autofocus lens is AF-P lens which uses a “Pulse” motor or “Stepping” Autofocus motor making it even quieter and smoother to autofocus than AF-S lens. According to Nikon, AF-P lenses are ideal when shooting video with a DSLR camera. Some of the Nikon's newer AF-P lenses let you set certain settings from the camera's menu system (VR, AF/MF for example) but on older model lenses, you still have to switch those modes on the lens barrel itself like you do on AF-S lenses. Sometimes, even if your camera supports newer AF-P lenses, you might need to upgrade the camera firmware to be able to set lens’ parameters from the camera menu.

Since the lower end Nikon DSLRs such as D3000 and D5000 series do not have the focus motor built-in, if you want to manually focus using AF-S or AF-P lens, you have to switch the focus mode on the lens barrel from A or M/A to M (box 2 in the picture above) and then rotate the focusing ring on the lens. Since there is no mechanical coupling between the camera body and the lens for Autofocus, most of the higher end lenses let you focus manually in M/A (or A/M in some lenses - works same as M/A but manual focus is less sensitive than M/A) mode as well. The reason behind making such consumer level Digital SLRs without a built-in focus motor is to reduce the size and the weight of the camera for portability.

Conclusion: If you prefer to use Autofocus feature, either you have to upgrade your camera body or the lens if you can't afford upgrading both at the same time. If you want to keep the same body and upgrade your lens and feel comfortable shooting with 70-300mm, you can go with either AF-S or AF-P version of 70-300mm which might be little more expensive than your current lens but you get the VR feature as a bonus. And when you upgrade your body to FX format later, the lens is compatible with the newer body as well.

If upgrading either is not an option at the moment, you can continue using your existing combo and manually focus the lens using the focus ring on the lens barrel. While shooting manually, the green dot, which is visible in the lower left corner of the viewfinder, will confirm that your subject is in focus. When you want to focus, rotate the focus ring on the lens barrel and when it lights up green, the subject is in focus.

I hope this blog helps you to make your decision. Thank you for the question and keep shooting!
