Is that really true that putting "your light source closer to your subject, makes the light much softer"? I thought it was the opposite.

As well as the intensity increasing, there's also the effect of the Inverse Square Law making the fall off sharper, which can make it seem like the light is harder.

But for the quick and dirty experiment with 'large close soft' and 'distant point source' try this.

Photograph model 2" from a window with a diffuser (voile) take subject outside on a bright day lit just by the Sun.

You don't have to do that experiment, just imagining it gives the answer.

A part of the answer also is as illustrated. The apparent size of the softbox is similar with respect to the model. A larger one further away has the same apparent size as a smaller one closer up.

A larger one closer is softer than a smaller one close up. Inverse square law applies. Light falls off, spill factors in.

I also see no issue with the images shared and I actually think the lighting is great. For my own shot, I used a
Godox Ad-s7 soft box (very small) on my AD360II from about 10-12ft away and i use this very much often. I love the results I get..

Really nice. I was having trouble seeing how the right side of the subject's face was more illuminated since the key is on the other side...... then I saw the tape mark on the floor......... so the reflector is actually imparting more light than the key due to feathering? exposure settings? Thank you

The subject rt side is not more illuminated than their left side (key light side).If you look there is a direction to the light. The shadow falls on the subject rt side/camera left (nose and jawline) See both photos. Quality is very soft but still models. I like to work with the key light in very close to get the really soft quality and it is feathered. The subjects left side of the face/camera right is almost a full stop brighter than the shadow fill side.

Yes, I can see that. I guess I was looking at the hair and jacket on both sides and was wondering where the extra light on the fill side was coming from. I'm still learning, by no means an authority.

I would play around a lot with different modifiers to see the different quality of light each can give. Also play with source to subject distance and feathering. I tend to use a few lights as needed. For single and couple portraits I usually never use a fill light. Only a reflector and I wok in very close with a large soft box 20 X 30 feathered and a white reflector for the quality of light I get from that set up.

Yes. A reflector does not leave a shadow like a second light can.

Not an expert, by far, but a reflector can't provide more illumination than the main light surely? The light has to travel past the subject to the reflector and then back again, so it must fall off more from the increased distance and losses from the reflection? Or am I misunderstanding something?

Pretty true. How Much Depends your desired results with the reflector(s) and how used. Types - any color. White, silver, gold, mirror, gray, black. Possibly more than one light or reflector being used. You have full control

I was thinking the main light was feathered away from the subject, just barely illuminating her, and the reflector was receiving the full amount of the main and reflecting back, thereby making the hair on the non-key side brighter. But then, I spend way more time reading on POTN than I do actually shooting studio LOL

It is feathered. Skimming in front but I use the white side of the reflector so it doesn't over fill. I need the modeling to give the portrait some depth. But I really love the soft gentle light. Like north window light.
