Once your vacation is over, you probably will want to download and tinker a bit with all the photos you took. Unfortunately, most people use pretty basic software for this. Perhaps the learning curve involved with some of the more sophisticated software keeps many people away from trying them. But we encourage our visitors to get creative and use Photoshop or a similar program to take photo editing to the next level.
Granted, Photoshop is a professional grade software that might not be right for everyone. But if you are a serious hobbyist or even an avid traveler, you will be thankful you have such a nice program to process your images. The good news is that now with the cloud service, you can sign up to use the software only when you need to. (It works on a monthly subscription model). Alternatively, you could download a free trial of Adobe Photoshop and use that, but it will only be good for 30 days and after that period of time you will need to decide whether you want to keep it.
If all you want to do is publish photos pretty much as they are taken, you can stick with whatever program you are currently using. But if you want your photos to have an artistic flair, give photoshop a try.
