Frank Reilly Value charts for different lighting condtions--my attempts

[skatay]

Hi everyone, I'm a bit of a novice painter. I took classes with Jack Faragasso at the Art Student's League in NYC for a couple of months. Faragasso was a student of the great Frank Reilly. In my classes I did a ton of value studies, but sadly for me, I only finished one painting (my own fault--I had some commercial work that required me to leave the class)

which actually has my poster cropped out. I post it here so you can get a sense of what my skill level is or isn't. Anyway, I decided I wanted to try and make value charts for myself for photoshop painting, since I want to do illustration work, and since value changes was Reilly's forte, I made my first chart. I'm pretty sure it's dead on, since it's mostly math at this point.

Anyway, this chart is for indoor form lighting, normal strength. It shows how values should change under those conditions, in light, shadow and a generic halftone, or, for detailled areas, a halftone in light and a halftone in shadow. Is this interesting to anyone here? Should I post more as I make them?

im confused.. what exactly are you doing with the charts? and did you make that chart or is that one you got? seems like a nifty tool to have around..

the chart shows how, in indoor form lighting, apparent values change.

So, if something is value 10, white, it's value 10 in light and value 4 in shadow under normal indoor form lighting.

The first column shows the original values.
The second (the line that's black and white) column shows the limits of the lighting condition, basically which values are values you will find in light and which ones are shadow values, but only in this particular lighting condition.
The third, fourth and fifth show examples of shadow light and halftone of the original value in the first column.
I've also included a halftone in shadow and a halftone in light to expand your rendering options.

Remember, this is for one lighting condition only, form lighting--indoors. Rim lighting, backlighting, front lighting-- all have different charts. And outdoor lighting is a whole nother can of worms!

I hope that answers your questions. Reilly learned this all himself, namely that black is value 4 in the light, and white is value 4 in shadow with this particular lighting condition (only). all I'm doing is some dividing to give you the averages and percentages as value numbers in swatches, or the B in HSB in photoshop.
