There is a great deal of info online on the benefits and drawbacks of various photo types so this message is just going to discuss it from the Jewellery product photography viewpoint.
What is a Raw image?
What it is: A raw image is a picture that is downloaded and install from the cam with all the video camera settings made use of to take that photo– setups like white balance, direct exposure, color histograms, etc.– and also these settings can be modified making use of Lightroom or other editing and enhancing software application after the picture has actually been taken. These setups are embeded in the cam prior to taking the picture so being able to edit these after the image is taken is an effective function.
For photos that are taken in reduced light or at events like wedding events, sporting activities, wildlife, and so on, lighting varies from shot to shot. Capturing in the raw style, lets you take care of these types of lighting (as well as other) problems while modifying. As a result of all the additional information saved in these data, raw data can be as much as 10 times the file size of a jpg (with the very same picture measurements).
For product digital photography, because the illumination is regulated in the workshop, refining raw data does not add much value. JPG documents can be edited as well, simply not as long as RAW. And that level of editing is sufficient for product work.
What does RAW represent?
RAW does not stand for anything. It literally indicates the word ‘raw’ as in a photo with all information intact and no compression. The majority of sites as well as manuals refer to it in all caps, which causes some complication. I had to google it as well.
What is it: JPEG is the internet requirement, mainly since it’s a compressed documents, so it loads rapidly on the web. The disadvantage is that every time you modify as well as save a jpeg, the high quality weakens, since with each save, the file obtains increasingly more compressed. Nevertheless, if you’re using a device like Photoshop, you can save the data in max resolution (this tells photoshop not to press the documents so the top quality stays undamaged).
When it’s best used: For many internet applications as well as printing in little to tool dimensions.
Given the above, it’s ideal for product digital photography considering that you desire photos to fill rapidly on your website and print on magazines or postcards.
What is it: TIFF documents are uncompressed files that a step in between RAW and JPEG. After modifying your RAW documents, you save it as a TIFF. The primary distinction in between TIFF and JPEG is that TIFF stores shades in CMYK style, which is what printing presses utilize. So the shades can be more accurate for printing. Nevertheless, these days, with advancements in printing technology, the differences are as well small to discover.
When it’s best used: When printing images on huge posters, etc, TIFF is much better to use than jpeg, but not by a lot. If your JPEG is in high resolution, you will hardly construct out the difference.
For product pictures, which are mainly utilized for the web and smaller prints, TIFF is not required.
The majority of major advertising agency (and also digital photographers who do benefit them) will utilize RAW and TIFF documents due to the fact that they focus a lot more on print. A lot of websites utilize JPEG because it lots faster. You can most likely to any type of major retailer like Nordstrom, Macy’s etc as well as download photos from their item web page and also you’ll see that they are all jpg’s.
What issues is whether the image represents your product well in terms of shade and clarity. The style is a technical feature that shouldn’t matter for product digital photography.
