Tips for making an outdoor Shooting?

I absolutely love to take my dolls for outdoor photos and nothing permanently damaging has happened to me so far -- except for one time someone decided to tip over on concrete lol --
So some of my personal habits are:
I go out when the sun is less intense, cloudy days, partly cloudy, and golden hour (when the sun is close to the horizon) all can yeild gorgeous shots in different ways. Your doll gets a bit less UV and I don't think dolls exactly photograph great in super bright midday sun anyway. If you are going out at midday then a spot under a shady tree will photograph better I think.
Have something practical to carry them in that prevents them getting dirty, damaged, or wig being messed up too much. The face can always be protected with something like a thick sock or soft cloth. I bring a pocket comb for emergencies but if it's very windy you will be grateful for a securely fitted hat or bonnet on them instead of a bare head.
My dolls get a bit of dirt on them when we go out sometimes and I don't find it a big deal. I find it comes off with a gentle cleaning with just water or a magic eraser. I handle them treating the face and hands as most precious and it's not failed me yet.
Basically id like to reassure you that taking your doll for outdoor photos doesn't have to be damaging. Resin colors are pretty stable unless they get excessive UV over time I think, and if you generally handle them with care it's not a problem.
Some random things I recommend is if you are going on on outing it's probably better to keep them in a bag with you vs in a car because of theft and excessive heat or cold in a parked vehicle. And if you want to stand them for full shots outdoors it's a matter of much more bravery than indoors. A doll stand might be a good investment or like me you can just be very careful and have fast reflexes, suede the dolls to prevent sudden joint repositioning and avoid high wind (but even then I do have the story about the concrete haha)

 

I second AlisonVonderland's post. I love doing outdoors photoshoots with my large 1/3 dolls, so here are a few more tips on outdoor shoots in general.

First tip is about setting/location. Observe your surroundings when you're out and about! Dolls are small, so locations that look bad for human photos often look great for dolls. Start in your backyard if you have one. Even in your local neighbourhood, I bet there are little spots and corners that will look amazing for doll-sized photos. Here's a thread for location inspiration.
(But, don't trespass onto private property. Ask permission for entry if possible. Pack up and go if you're asked to leave. If you're not sure if it's private or public property, best to assume private. Please be a good citizen. )

Second tip is - improve posing by sueding joints, tightening strings, even wiring the limbs. Plenty of tuts on how to do this. This tends to be more important for large dolls since their weight can make posing harder (but sometimes easier too); and for outdoor shoots you want to spend more time taking photos, and less time wrestling with your dolls to hold their poses. I've sueded my dolls and keep their stringing tight, which has helped them hold poses.

Third tip is... just go for it. The more you do outdoor shoots, the easier it gets - finding suitable locations, snapping good pics, getting familiar with your doll's quirks and how well they pose... and just getting used to being that peculiar person taking photos of dolls in public, haha. Also, the more you do it, the more serendipity/happy accidents you will encounter - perfect lighting, something appearing in your shots that looks amazing. On the other hand, more outdoor shoots means more risk for a doll to fall over... but you're never too far away from them when taking photos, so if your reflexes are fast you can generally save them before they damage themselves. And maybe some photoshoot days are write-offs -- lighting isn't good, can't find a good location, doll doesn't want to pose today -- but that's fine, just do it again later.

Overcast days, and evenings, are the best lighting for good pictures, and less UV on your doll. I'm not so worried about dirt on resin, most of it can be removed, and a well-sealed faceup is quite durable. I tend to be more concerned about getting doll clothes dirty - they're trickier to clean/launder than resin.

Materials I bring with me: cloth bag that my individual doll is stashed in (so their faceup/wig aren't messed while being toted about), outer tote (a large shoulder bag or doll carrier), a toothbrush to comb wigs and brush away any stray dirt.

I find outdoor photoshoots exciting and always rewarding, the photos are totally worth the effort. Good luck with it!
