One of the most common questions often asked by new astrophotographers is whether to shoot in RAW or JPEG format. Generally, we highly recommend shooting astrophotographs in RAW format. RAW files usually contain all the data (including the intricate details) captured by your camera’s sensor during the shooting. This gives you greater flexibility for post-processing and enhancing the image’s quality. You can post-process your pictures without sacrificing any detail or quality.
This is especially important in astrophotography, where you are shooting in low light conditions and require precise or accurate settings to bring out the best in the object. RAW image format will allow you to adjust your exposure, contrast, color balance, and vital other settings without degrading the quality of your pictures or introducing artifacts to the shots.
Apart from these, shooting your Astro pictures in RAW format offers several other advantages over shooting in other formats, such as JPEG. Some of these include:
- Better color accuracy: Color is very important in astrophotography, especially when you are capturing celestial objects other than the moon. Shooting in RAW image type or format will allow you to capture more color information accurately when compared to shooting in JPEG.
- Greater detail and dynamic range: In RAW image type mode, you can capture more detail and have a greater dynamic range. You will be able to record more subtle variations in color and brightness.
- Non-destructive editing: Shooting in RAW mode will allow you to reverse or modify, at any time, any editing done to the files without losing image quality.
- Higher image quality output: RAW files usually contain more information than JPEG files; thus, they can produce higher-quality output, especially when printed at larger sizes.
While shooting in RAW mode has several advantages, there are also some disadvantages that you should be aware of. Below are a few of the main disadvantages of shooting in RAW for astrophotography:
- Larger file sizes: RAW files are much larger than JPEG files, which can take up more storage space on your memory cards and hard drives. This can also slow down the speed or process of transferring the files from your camera to your computer. Additionally, editing RAW images often requires more processing power and memory than editing JPEG files, so you may need to invest in more powerful computers to handle the workload if you must shoot RAW.
- Slower shooting speeds: Because RAW usually captures more data than JPEG, your digital camera may take longer to write the data to memory cards, which can slow down shooting speeds or cause your camera to buffer.
- Limited compatibility: Not all software programs support RAW files, so you may need to convert your RAW images to a more widely accepted format like JPEG or TIFF if you want to share or print them.
