equipment to buy
The best way to increase the quality of your photography is to invest in a decent DLSR camera and lights. Lighting is optional and using natural daylight can be a good way to go, however if you need crisp clear product images for an online store or catalogue then lighting is a must.
The initial investment is large, however after that the equipment will pay back once you start creating stunning content marketing and increasing sales and customer base.
When it comes to editing software, Lightroom and or Photoshop can be purchased on a monthly basis and will polish your images and give them the wow factor. Below I've detailed my recommendations for cameras and lights and you can click here to Adobe for their software packages.
Park Cameras in Burgess Hill are a great company with experience and knowledge and they have a great package available on the Canon 4000d which is an entry level DLSR and would be a good all rounder for product shots. You can view this here
