Photoshooting products and using the photos on the internet or in a product catalog
Product Photography
There are many ways to photograph products. And there are many different applications for which it is required to deliver its files. It may be for a large print like a banner in a supermarket, it may be for a product catalog, but it may also be for exclusive use in an online store, where a completely different approach is needed and perhaps many more downloads to highlight the details of a product in 360 degrees.
What is certain is that when we photograph products, we must always take our shots based on the post editing and how our work as graphic designers will be easier, faster and more efficient. There is a wide range of equipment from very cheap to very expensive. With the right knowledge and experience, a graphic designer excels in this part because he simply knows the process of editing / retouching very well, he knows composition, color harmony, etc. He knows exactly how to move even when there is not the right one. background in cases where the occasion needs it, because it can very easily insert a photo into it with techniques in photoshop.
He also knows in what format his photos must be in order to correspond to the respective project. Another resolution has to be one photo used on the internet and another when it is intended for printing. Amazon & Google for example have their own photo guidelines for ecommerce ads and we all know they are the best of their kind. The right photos, like a good graphic designer, mean more money for a business, no matter the size. They are necessary because they show professionalism and inspire confidence in the consumer. It's one of the most important factors in exhibiting your products because in essence "good photo = good impression = correct information = purchase"
Use in web VS printing
The specifications of a photo intended for use in an eshop are different from the photo intended for use on social media and completely different when it is to be printed. Printing uses many different resolutions depending on the size, method and material on which a photo is to be printed. In no case can we have the same resolution in an A5 booklet and in a 1.5x2 meters banner. The larger photo may print smaller, but the smaller one will print catastrophically on a larger surface. Now when it comes to the internet, we have a completely different approach because we take many parameters into account. Use on Facebook may contain a photo on a busy background, but in an eshop this is prohibited. The customer must and wants to see clearly the object and its details so that he feels comfortable to buy what he wants. Product photography is a science in itself and requires special knowledge so that the result is even and translates directly into profit.
