Outside the greenhouses

Guy resting outside the greenhouses ( is that one word?) at the Botanical Gardens.

I tried sharpening this one after shrinking it, but it still looks blurry to me.

I don´t understand how to keep photos sharp after lowering the resolution a lot…

  1. The other thing to consider is using RAW files from your camera versus JPG files. I won’t go into that unless you’d like me to.

    • Raw.. yeah… I´m scared to death of it.. I´ve been reading about it but the DNG thing sounds like a hassle and giant files… It´s not that I don´t have enough space on my computer either.. or RAM or anything.. I think maybe I should actually try it. 🙂

      • RAW is nothing to worry about. First you’ll need to make sure you have some software that can process the raw files from your camera. There’s no universal standard for what a RAW file is, so different camera manufacturers produce different kinds of RAW files. None of them are actually called RAW. DNG is Adobe’s RAW “standard” that almost everyone ignores except Pentax. We still love computers!
        But chances are you’re currently using something that can process the RAW files from your camera or the manufacturer gave you something on the disk that came with the camera. There’s also free stuff available that can work with RAW files.
        I have a 16mp camera that produces RAW files about 16MB in size. That’s maybe 3 or 4 times larger than a high quality .jpg file the camera would produce for the same image.
        The RAW editors are similar to editors that work on .jpg images. They’ll do basic editing stuff like exposure, contrast, saturation, cropping, straightening, etc. There’s a little bit of a new learning curve. The advantage of using a RAW editor is that it’s unlikely to lose any of the basic detail of the image during adjusting. A .jpg editor can lose details depending on a number of factors.
        Having said all this, a RAW editor might not help this photo much. This one looks a little too compressed (shrunk), losing a lot of detail and making the photo look grainy. Still sharp, or in focus, but grainy as in an old not so good film photo.

  2. Some images compress better than others. In general, the more detail there is in a photo, the greater the loss of quality when compressed. This photo has a lot of detail. Some images will look much better with a small file size, others will look really bad. So there’s no perfect compression ratio or file size for every image. You’ll just need to evaluate every image for what looks best to you. I try to keep my images between 250KB and 500KB. If I did the math correctly, that works out to between 1,000 and 2,000 images per GB of storage. That’s a lot of uploading. WordPress should tell you how much space you’re using to store your images. That’s on image library page. You’re probably using far less than you think.

  3. I also noticed that the image is 118KB in your blog post on my browser. When I click on the image to open only the image in a new tab, the file size is 238KB (twice as big) and looks slightly better. So either the browser (Chrome) or WordPress is showing a further compressed image than what you probably uploaded. Don’t we just love computers!

  4. Looks sharp to me. However, what you may be seeing is a loss of details. That’s going to happen to some extent whenever a large image file is changed to a small file (image compression). That’s just the way digital images work. WordPress also seems to further compress the images in my opinion.
    Whatever method you’re using to compress the image probably has a slider, or some method, to control either the “compression ratio” or the “quality” of the compressed image. You can play around with that to see how it affects the new image. You can probably get a better image, but it will produce a bigger file. In the end, it’s a compromise between image quality and file size..

    • Yes thank you! I think something happens to them when they get in here as well ( what you said about WordPress compressing them even more). It could also be my eyes that aren´t so great, but I think they look fuzzy.
      And yes, it´s hard to find a good size, I don´t want to waste space either. Ugh, I´ll have to keep practicing I guess. Thank you for the advice! 🙂
