How do I shoot Panoramas in raw mode?

I have been using Nikon d3300 for a year now and I have always shot my photos in RAW. During my last vacation I took some Panoramas using the Panorama Easy Mode and when back home I noticed that the Panorma photos were in JPEG not in RAW. Is there a way around this?

Set to shoot to RAW then take your shot making sure your scene sits on either the top or the bottom of your frame. In the computer, open your RAW file then crop the bottom or top to get your panorama.

Exactly the same way you would using a JPEG image file.

Once you have created the panoramic image file (in RAW) export the resulting image as a high resolution JPEG

Look on page 55 of your manual. It states that raw format is not available in many of the scene modes, including easy panorama.

When shooting a pano, you can do it the old fashion way which is set your camera to manual exposure and take a number of overlapping images (overlap by about 30% or more). Overlapping the images allows the stitcher to remove lens distortion and correct vignetting. Rotate the camera about the nodal point which is where the apparent aperture diaphragm is located (about the mid point of the lens barrel length is a reasonable guess). Rotating about the nodal point is important if you have scenery close (within 30 feet) to the camera. If no scenery is within 100 feet, then rotating about the nodal point is not a big issue as parallax issues will be tiny. There are many web sites that explain how to take a proper panorama shot set.

Convert the raw images in to 16-bit TIFF images if your stitching program doesn't allow raw images. Nikon supplies ViewNX2 with the CD that came with your camera, or you can download the program from Nikon. ViewNX2 allows you to convert raw to TIFF.

Use a stitching program. Adobe Photoshop and LightRoom have photo merge functions to create panos. Photomerge is fairly easy to use and works well.
Hugin, free; powerful, and mildly confusing; is the stitcher I use due to better functionality over Adobe products.

"Scene modes" are typically for people who are clueless about photography and have to have a camera make decisions for them, and thus they always only function in the amateurish Jpeg mode.

You can certainly do pano shots in RAW, but YOU have to do it manually with YOU in control of everything, as has already been stated.

Not in camera. The panorama mode takes the RAW information and then processes it and saves it as a JPEG. To do this with RAW images, you will need to make a series of shots and blend them in Photoshop. You can do this as DNGs or TIFFs. Using the TIFF file format could be a good option because just like RAW files, TIFFs can be uncompressed and up to 32-bits in size.

Do a search on YouTube on how to shoot panos. You will need some kind of photo-editing software like Photoshop CC or Lightroom CC that will allow you to blend multiple images together.

Shot in RAW as a series of photos which can be comped together later. Then do the panorama comping in your computer.
