You are the lower shutter speed then photo will long expoSure and the shutter speed will high then the its it will complete the exposure value.

You focus the subject and try to low shutter speed and high shutter speed and then show how was the photo

LR Classic is basically what we all are used to what earlier used to be LR CC (Only Desktop based).

The LR CC is the new addition in LR list and is a stripped down version of LR Classic. Good thing about LR CC is you can sync your photos across devices (Desktop, browser, phone, tablet.)

But then the new LR CC has many new features missing. You don’t have Tone adjustments, Split Toning missing, Camera Calibration panel missing, no face recognition, no healing brushes, no upright tools,

BIG DRAWBACK: Adjustment History missing (OMG!!). if you are used to making HDRs and Panaromas in LR, then new CC lacks the feature. Heck, it even does not allow you to add Watermark on a photo. You will have to move the pic to Photoshop, add Watermark and then save (that’s a lot just for adding Watermark).

No Print Module-so you can’t work on collages.

Advantages of CC: Automatic Backup to Cloud, Sensei keyword tool- This will keyword your photos when you upload it to cloud. So when you check for any ‘lake’ photos it will list all lake photos, or you search for ‘kingfisher’, it may list all kingfisher bird. I can’t promise that Sensei will behave as it promises, but this is how it is supposed to behave.

LR CC: You can only save 1 TB of Photos on Cloud after which you will have to buy more space

LR Classic: Unlimited as everything is stored on your Desktop.

LR CC is good for casual Photographers who need to put images immediately from anywhere on social platforms...LR Classic is for a little serious Photographers

It totally depends on what you are shooting. For landscapes, usually f/8-f/11, ISO 100 and shutter 1/250 or higher during day time. Similarly for portraits, f/2.5, ISO 100 and shutter 1/250 or higher.

1. Shooting with 50mm lens can let you shoot at aperture as wide as 1.8 but a 18-55mm will allow you to shoot only at 5.0 aperture 
2. This difference itself is a huge deal. This means you can have the advantage of having faster shutter . Imagine shooting handheld at 1/15s with aperture f5.0 and then at 1/125s with aperture f1.8. This can be significant in low light conditions.

The only thing you need to do so is a DSLR.

It also depends on  DSLR as to which type of AF technology  it uses or what are the diffrent types of focus points that the camera has.

And just automatically or manually focus your subject and you are ready to go.

By this you should be ok to focus on.

Any lens with 24mm or less focal length would be ideal for landscape photography. Lenses with 18mm or less will provide wider perspective. Usually focal length range 10-15 mm are used by professional landscape photographers.

First of all that you should not try to disturb the audience. Always try to capture pictures from roaming around the walls of auditorium. Better to go with Telephoto for taking candid shots for stage subjects or from the audience.

Another thing is that you can use another camera for wide angle shots of entire stage or the audience.

Any telephoto lens with focal length 200mm and above would be good. This is generic and affordable for most of amateur photographers. 

If you are willing to specialize in wildlife or willing to venture out in wildlife photography, can go for 150-600mm lens.

Types of equipment that are needed to shoot long exposures

A tripod – this is a good piece of equipment to have in most instance, but is a critical piece of equipment for shooting long exposures. Make sure your camera is properly mounted on the tripod before you start shooting.

A camera – obviously you will need a camera, but many people assume you can only do this type of photography with an SLR. Some advanced point-and-shoot cameras can also do long exposures if they have a Shutter Priority function. Take a look in your camera’s manual to see if it has this function, you may be surprised.

Cable release – your camera will be on a tripod, so it should be very still, however, sometimes the action of pressing the shutter release button can cause the camera to move slightly and this movement can cause your image to blur very slightly. You may not notice this on the LCD screen, but when you open the image on your computer, it will be evident. I recommend getting a cable release (also called a remote trigger). It is simply a cable that attaches to your camera and acts as a shutter release button. Using a cable release means you can set up your camera, step away from the tripod and press the button without touching the camera. Cable releases can be wireless too. If you don’t have a cable release or don’t want to buy one, you could use your camera’s self-timer function to trigger the shutter.

Camera settings should be used

Shutter speed – depending on the light in your scene, your shutter time will need to be at least 10 to 15 seconds, or longer if necessary. If you are doing a seascape and the water is moving quickly, then a few seconds may be long enough to make the water look misty.

Aperture – you will want to have your aperture set at anywhere between f/8 and f/16. This again will be determined by how much light is in the scene and how long you want to expose for.

ISO – keep your ISO settings as low as possible, ISO 100 is what I use for long exposures.

It’s normally a good idea to shoot long exposures as the sun is setting, or just after sunset. My suggestion is to be on the scene an hour before sunset. That way you can test some shots, make sure your composition is good and be sure all your settings are correct. 

there are 2 ways of achieving focus

Using Autofocus

turn on the auto focus mode on your lens->then point at your subject->click shutter release button half way to lock the subject in focus->adjust your frame if needed WHILE HOLDING THE SHUTTER RELEASE BUTTON->press the shutter release button to take your photo with subject in focus

Using manual focus

turn on your manual focus on the lens->point at your subject->use the focusing ring to adjust focus according to your eye->press shutter release button to click the photo
