What is DPI for Trail Camera
What is DPI？
DPI stands for Dots per Inch, referring to the number of ink droplets a printer will produce per inch while printing an image. The more dots of ink per inch the picture has, the more detail you will see when printed.
How does DPI differ from PPI?
PPI (Pixels per Inch) refers to the number of pixels that make up every inch of a digital image. It’s used to describe image resolution on a screen, rather than in print. DPI, meanwhile, refers to number of dots in every inch and is generally used for print purposes.
PPI and DPI do however serve very similar purposes, indicating the overall resolution of an asset. This is also why PPI can be easily confused with DPI resolution.
How to find the DPI resolution in In Design.
You can also find the DPI resolution of an image using Adobe InDesign. InDesign is professional page design software, perfect for editing and designing posters, magazines, prints and banners.
InDesign uses two terms to refer to resolution — Actual PPI and Effective PPI.
Actual PPI is the resolution of the image while at 100% of its original size, meaning when the image is at its original dimensions without being resized.
When you enlarge an image, the existing pixels are stretched to accommodate the new size. This is where Effective PPI comes in. This refers to the resolution of the image based on how it is placed on the InDesign page — showing how the final product would look if it was enlarged or reduced in size.
So, for instance, if you wanted to print an image at 300 DPI, you would need to make sure the image has an Effective PPI of 300.1.
Is a cellular trail camera worthwhile?
It depends on your needs. Cellular trail cameras can send images and videos to your cell phone or computer from far away. Some high-end cellular trail cameras can offer you live streams. All these are made to let know what's going on outside without frequently visiting the field and leaving scents to disturb animals. However, such features tend to consume more power and occupy more storage capacity. Also cellular trail cameras are relatively expensive and you may need to pay for extra cellular plans. If you are an expert hunter or wildlife observer who wishes to know what happens anytime, you can consider cellular trail camera as your option. If you just need it to shoot images only when animals pass by, you can choose non-cellular trail cameras.
What is the best resolution for a trail camera?
Generally speaking, the real resolution of a trail camera is 2-5MP. The higher, the clearer. One thing you should know is that images in higher resolution will occupy more capacity. You can visit the website of the manufacturer to see the real-world pictures caught by the camera and decides whether the image quality is good enough for you. For trail cameras, 4MP resolution can offer you clear images and videos.
What's the difference between white flash, low-glow flash, and no-glow flash?
Simply put, the main difference between these three kinds of flash lies in the night vision effect. White flash can emit bright light in order to take colorful and clear pictures in the darkness. However, it's so obvious that animals may be scared. Low-glow flash, or IR flash, is not as obvious as white flash because it emits infrared light that is less visible to alert animals. But the images taken are black and white and not as clear as those taken by a white flash. No-glow flash, or black flash, emits light that is nearly invisible. It's hard to be seen and won't scare animals at night. Pictures taken are also black and white, but they might be darker and fainter than those taken by low-glow flash.
