The quick answer
Start beside a window with indirect daylight and turn off nearby room lights for a simpler setup. Photograph the face turned toward the window, then slightly away. Compare the shadows and eye detail before choosing your position. A sheer curtain can soften direct sun, but it also reduces the available light.
Choose the light you actually have
Look at the shadow beside your nose or on a hand held near your face. A sharp edge suggests a harder source; a gentler transition gives you a different portrait mood. Do this at the time you plan to take the photo. A window that works in the morning can look very different later.
Adobe describes indirect window light and translucent curtains as accessible ways to create softer indoor light. There is no compass direction that works best in every location and season. Start with the visible light, rather than a rule about which wall your window should be on.
Make the room easier to work with
Simplify the light. Switch off nearby ceiling lights and lamps for your first comparison. Nikon’s window-light advice uses this approach to make the relationship between light and shadow more deliberate.
Pick a quiet background. Look through the camera for doorframes, bright screens, and objects crossing the outline of the head. Move the camera or subject until the background supports the portrait.
Start with a comfortable position. Sit or stand beside the window with the face turned partly toward it. Leave room around the head and shoulders. Avoid choosing a pose that is difficult to hold while checking the photograph.
Check the bright cheek. Take a frame and inspect both sides of the face. If the lit side looks blank, adjust exposure if your camera permits, or change position. Keep some shadow if it helps show shape.
Try a three-frame comparison
Treat this as a small exercise, not a fixed lighting formula. Keep the same crop and expression while changing one thing. Save all three versions so you can compare them together.

Question to ask
A: toward the window
Turn the face more toward the light.
Can you read both eyes without the face looking flat?
B: across the window
Turn slightly so light travels across the face.
Does the shadow add shape or hide an important feature?
C: a different distance
Move closer to or farther from the window and repeat your preferred angle.
Which position balances face brightness, background, and comfort?
Solve the problem before adding a filter
If a stripe of direct sun crosses the face, try another position or a sheer curtain. Check the result again after adding the curtain: less light may mean you need to hold steadier. If the shaded cheek disappears, turn toward the window a little rather than automatically brightening the entire photograph.
For a useful selection process, score your three frames on four simple questions: are the eyes readable, does the expression feel comfortable, is the background distracting, and is the crop usable? Pick the frame with the fewest problems to solve. A photograph does not need perfectly even illumination to be worth keeping.
Once you choose a frame, keep an untouched copy. You can then explore a different mood while comparing the result with the light and features that were present in the source.
Common questions
Do I need a professional camera?
This exercise is about the position of the face and light. You can try it with a phone; the exposure and focus controls available will depend on your device.
Should the window be behind me?
For this starting exercise, place it in front of or beside the face. A window behind the subject creates a different exposure problem and can turn the face into a silhouette.
Does soft light mean no shadows?
No. Look for a gentle transition at the shadow edge. You can still keep a darker side of the face to create shape.
