"...any tips on editing, such as to soften wrinkles from harsh sunlight? " Craig typical industry recognized methodologies for successful Beauty Genre imagery is multifaceted...
First and foremost always wise to hire an agency represented talent who works that genre. You can speak with one of the agencies bookers and share your client's requirements. That said, ideal talent tend to be at the very young end of the spectrum. i.e. 16 etc. although I've found 14 year olds to have wonderful skin texture (however please realize at 14 to 16 they must be accompanied by their parent/guardian (the only exceptions are emancipated minors). In my market this is germane
https://law.lis.virginia.gov/vacodefull/title16.1/chapter11/article15/Second Makeup Artistry can (and often does) go a long ways to mitigating issues with skin texture... Bridal Makeup Artist deal with this constantly. The tools of their craft? Toner, Concealer, Foundation, Matt Powder however it is an art form and the application of the above which is far more important than the actual tools/product involved.
Third and probably the most important of all, Illumination! Avoid harsh side lighting if at all possible, for it will accent and strongly emphasize the bias relief of a talent's skin textural anomalies. A Classic example of this is your breathtakingly stunning landscape rendering of Saguaro Cacti in the Sonoran Desert.
https://www.uglyhedgehog.com/t-773998-1.html Kudos to this magnificent use of strong, low angle slide illumination! Yes, shoot straight on axis for minimum bias relief... A 24" Beauty Dish with grid brought in close 2' above and 2' in front of talent paid the bills here.
As for "philosophy ... for catch light reflections in the eyes?" Craig a let them fall where they may... however if there is an aberrant deviation i.e. missing altogether then I will retouch to balance what should be present.
In this example there are two catch lights, one larger higher up and a "micro dot" far below it. The large circular Catch Light is a reflection of the Gridded BD (Beauty Dish) while the "micro dot" is a reflection of a Nikon SB-700 in Remote SU 4 mode on the floor 3 feet in front of the talent. The only team member on this shoot was our studio's hair stylist, our lighting assistant wasn't available so the Nikon SB-700 with diffusion dome was used to provide fill and soften the shadow under her chin.
Finally on "editing" a.k.a. PP (post processing)? I use Adobe Photoshop's Spot Healing Brush and Clone Stamp exclusively... However my mentor taught me to use them very sparingly... Her philosophy was "If the image looks like it has been retouched you have failed"
Hope all this makes sense Craig or is at least food for thought..
And I deeply appreciate your very kind words on my efforts here, they are cherished.
Oh, Best advice? Try and assist other commercial beauty genre photographers in your market, this was how I learned my craft.
Cheers! And all the best on your photographic journey Craig!
