There are several tips that you should use while taking photos for your travel blog. First and foremost, you should ensure that the camera you use is of high quality and one that can actually take clear high resolution pictures.
In addition to simply ensuring the camera is of good quality, you should also ensure that the settings for the camera are appropriate for the picture you want to take, For instance, in case you are in a place with poor lighting, then you should set the camera to take good photos despite the lighting conditions.
Thirdly, you can improve the overall output of your photos by having a different person to take the photo instead of yourself.
Finally, it is important to avoid insisting on each photograph being a selfie. It is not a must that you appear in each photo since this might undermine your ability to take some photos especially panoramic photos.
