Taking blog/outfit photos is not easy, especially if you don't have a professional photographer following you around! I certainly don't have one, but I have great friends and family that volunteer as tribute and put up with me during shoots. Here is how I suggest fixing the problems y'all may have while taking pictures!
The Problem: You have no one to take your photos
The Solution: Purchase a tripod and remote for your camera! A lot of bloggers do this. If you don't have someone around that is willing to take pictures for you, invest in a tripod and then you'll be able to take your blog photos whenever you want. If the remote seems obvious in your photos, pose in a manner that hides it.
The Problem: You don't know how to pose for photos
The Solution: It takes a ton of practice. Try to act as natural as possible so photos don't seem over-posed. Candid shots are great. It takes time to get this stuff down, but with every photo shoot you'll see your poses improving. If you don't want to seem stiff, move a little! Sometimes I walk around while shooting and my mom keeps snapping photos. Relax and you'll be fine, I promise!
The Problem: You want to shoot in public but hate it when people are watching you
The Solution: Take photos early in the morning! I take mine at the park before work because less people are around at 8:30am. Bonus–– the lighting is also better at this time rather than at noon.
The Problem: The lighting is off in photos because the sun is too harsh
The Solution: Shoot during Golden Hour if possible. Don't know when Golden Hour is? Look here and it will tell you exactly when it starts depending on your location.
The Problem: Your photos are not as "high quality" as you'd like them to be
The Solution: Invest in a DSLR camera. If you already have one but still are not satisfied, I recommend checking out a 50mm 1.8 lens. I use that lens with my Canon DSLR and LOVE it.
The Problem: You have nowhere "pretty" or "scenic" to take photos
The Solution: Shoot outside in front of a cool looking wall! I love posing in front of white walls downtown because my outfit pops against them.
The Problem: You shoot in auto and your photos are overexposed or underexposed
The Solution: Do not, I repeat do not, shoot in auto ever. Shoot in manual and adjust the shutter speed/ISO/aperture as needed. Take test shots and work from there! Don't know how to adjust these? Youtube has excellent tutorials!
