Size matters
May 11, 2018 09:26:52 #
I have 100's of photos and some are really good but the sizes are very low. They are all jpeg's shot from a Fuji 5700 and range from like 1.25 MB to 1.75 MB. Is there a way to increase the size after the fact or am I stuck with a bunch of undersized photos? Bottom line: I would like to submit some to a stock agency but I was told that many of the agencies require a minimum of 6 MB. I have moved to a Nikon D3300 and now shoot mostly raw photos. Still trying to understand and learn how the camera settings matter in every photo to be taken. So many variables........

The 5700 had a 7 meg sensor. Are all your 5700 pictures at reduced resolution?

You stated MB and yes it's easy to increase the MB. It's a bit more difficult to increase the MP and increasing the MP but in either case there is really no increase in quality. If you open your JPEG file and save it as 16 bit TIFF the size can increase 10 times. No more details are added though. If you upscale your image in software like Photoshop you can increase the MP and the resulting image may look a bit smoother but still no more details.

Any time you "upsize" a digital image, the software you use to do it must add pixels to the image. Example: You have a 1000x600 pixel image you want to double the size of, to 2000x1200. The original had 600,000 pixels, the new one will have 2,400,000 pixels. The software had to add 1,800,000 pixels to the image. When it does so, it has to guess at what color those pixels should be, based on the colors of surrounding pixels. The end result is tremendous loss of quality.
You also have to remember that megabytes and megapixels are two completely different things. The first describes the amount of disk space it takes to store it, and the other is a count of the vertical pixels times the horizontal pixels. Obviously, the more megapixels the more megabytes, but there is not a one to one relationship. The size in megabytes is also affected by how many different colors there are in the image.

How does one save an 8 bit JPEG as a 16 bit TIFF?

A better question is why.

Open it in Photoshop as a JPEG and save it as a 16 bit TIFF then check the size.
You can enlarge some photos using software such as ON1 Resize 2018 (used to be Genuine Fractals) but the image will probably have to be 5MP or better. If your images were taken with a 7MP camera, it should work. Any imperfections may show more with the enlargement though. There is a trial version you can try.

I only have Photoshop 6. There’s no option to save as a 16 bit TIFF. The size increases nearly 10 times, the dimensions remain the same, and it still is only 8 bit.

My bad, I thought there was an option to the quality of the TIFF when saving it in Photoshop. That option is in Lightroom.

I prefer 16 bit TIFF for all my digital images, and have a lot of JPEGs that I’d like to convert.

Thanks for that. Though I shoot mostly film, I’ll have to take a look at Lightroom.
