2. I have a nikon D3200 so with this select A for aperture so you gain access to adjusting the aperture.
3. Adjust aperture to the lowest possible for lens. So for when the camera lens is at 18 zoom it can go to 3.5 aperture.
4. Distance is a a key factor. I normally stand pretty close to my subject. I can say around 2 feet.
Hope this tutorial helped! Leave comments below!
