Living in Japan makes it a mystery to what the weather is actually going to be like. Of course, you can check your weather app, but the chances of it actually being accurate are slim to none. The best thing that you can do in this type of situation is to have a selection of outfits ready that can work with different weather types for the time of year. Always have a backup. For your pet, I know that it can be a bummer to have your pet freshly groomed and then they end up all wet. However, we can still make the best of it. Bring a microfiber towel or a cute pet raincoat. (Sessions are not held in inclement weather conditions)
2. Plan your session like you are having a party.
When having a party you don't just get it all together in 5 minutes. You make the list, buy the supplies, invite guests, etc. Treat your session like this. Who is in the photos? Will they all ride together? Will the outfits match or is everyone picking their own thing? It really helps to make a checklist and make sure that everyone does their part before the day of.
3. Be ready to go as soon as you arrive.
Ok, everyone arrives on time, the weather is great, pets are ready, let's do this! Getting started right away can help alleviated wasted time and help you get more out of your session.
4. Take direction from your photographer.
There is no issue in letting your photographer know if you want certain poses and styles, but it is very important that you take direction from your photographer to make the most out of your session. It's their job to know where to place you for the best light and the best shots.
5. Make this a joyful event.
Do not treat your session like a chore and it can make all the difference. Treat it as a family adventure to help set a better mood. It may be hot, cold, wet, muggy, or uncomfortable, but it doesn't last long. Besides, making the best out of it can keep you from having to do it twice.
