File formats

I've been shooting for a while but I'm a relative newbie when it comes to post. I always shoot raw on images that are important but jpeg for snapshots. Over the years I would process raw in Photoshop CS2 and save in raw and the snaps would be processed in Irfanview, saved as jpeg. Recently I've been saving and posting on Facebookin png from Irfanview because it seems smoother. Does this sound ok? I've been hearing a lot of other formats on the Hog and wondering if I'm missing out on something better? Are there any benefits of other formats that I'm missing? Storage space is not an issue.

I just use JPEG for posting. It's the most commonly used format.

Jpeg is the most commonly used format, but TIFF is widely used for intermediate editing stages where a raw format is not possible. When I've measured them png files are very close in size to tif but there are differences. Png files do not include the EXIF data. On the other hand, they do carry a transparency layer so that it is possible to, effectively, create odd-shaped images with png files.I've been shooting for a while but I'm a relative ...

I edit the raw files in LR or PS, then I save as .tiff. I'll save to .jpg if I have to mail them, etc.

Irfanview is great, isn't it? JPEG is fine for posting. If PNG works for you, why not use it?

Just a side question what's the difference between TIFF and JPEG files, and RAW for that matter although I understand RAW files contains much more data.

Tiff and raw are "lossless" files, meaning all of the information is retained in the file. In jpeg, the camera or the editing software (in forget which) discards a lot of the similar or closely related information.

I know you shoot raw or JPEG can you shoot Tiff or do you just rename a File tiff, not that I know how to rename a file either LOL

Some cameras do shoot in TIFF but you cannot make a file a different format by simply renaming it, you would need to convert it in a program. So you can convert RAW to TIFF or JPEG or PNG but you cannot convert JPEG or any file format to RAW. Web and email formats are generally PNG or JPEG, PNG retains transparency in an image that you might have created, for example a logo that you did not want a white background on.

Actually, if you take a look at the size of a RAW file and the corresponding TIFF file you will in almost all cases find that the TIFF file is much larger (i.e., the TIFF file has more data, often much more).
Data is different than information, however, and the RAW file is apt to have slightly more information than the TIFF file that is derived from it. But the TIFF file is formatted in a pixel-mapped format that is more convenient for processing as an image. The RAW file by contrast is formatted (at least roughly) in the way it comes off the sensor in your camera.

I shoot exclusively in RAW - never know when a snapshot will be deserving of more editing! Whenever I do any editing on that original, I will save as .tiff. This format not only preserves the information from the original RAW, it also preserves the edits such as layers that you have done. The steps you took [history] are not saved, but you can look at the layers and determine most of what you did.
When saving images on your hard drive, you can keep the RAW originals, save the edits as .tiff, and also save the edits [or originals] as .jpg. I keep my .jpg images in a separate category folder from the RAW and .tiff files. The .jpg format is best for social media and email. I am not familiar with .png, since I do not use it. Since space is not an issue, I would recommend keeping the RAW and .tiff files, only making .jpg for sharing online.
