Thanks for reaching out to the Stock team. There are various photographer's who contribute their artwork on the Adobe Stock website and their names are always listed at the top of the image. Please see the screenshot below:
So if you are using this image, for example, the credit line(photographer's name) which you should mention on the image should be "© [Leigh Prather] /Adobe Stock"
Hope this information helps!
Feel free to update this thread in case of any additional questions.
You are welcome!
