twangster Posted January 30, 2018 Report Share Posted January 30, 2018 My goal is to find the minimal photo size that properly represents an image to reduce server storage demands but also reduce Voom upload times. Smartphone and tablet users likely won't see a lot of differences, but folks with computers and large monitors may. Here is the same photo in four different sizes: 300 Pixels Wide, 59KB 500 Pixels Wide, 106KB 700 Pixels Wide, 170KB 900 Pixels Wide, 256KB Quote Link to comment Share on other sites More sharing options...
Lovetocruise2002 Posted January 30, 2018 Report Share Posted January 30, 2018 @twangster I think we need to see some food photos to properly judge I'm on my computer screen right now (laptop not tablet) and I still feel like the 900 pixels does it the most justice. The 700 is borderline ok. Quote Link to comment Share on other sites More sharing options...
tiny260 Posted January 30, 2018 Report Share Posted January 30, 2018 @twangster I agree with @Sabrinaklai , I'm on my PC so 900 is fine and 700 would work, I don't ever blog on my cell phone so I don't know what would look good on the smaller screen size. Thanks for all the great pictures. Quote Link to comment Share on other sites More sharing options...
LetsTryThisPlace Posted January 30, 2018 Report Share Posted January 30, 2018 I would like to find out too for my upcoming trip also @twangster what are the file sizes at one point the resolution to size wouldn't really make a difference. The 900 looks amazing but the 700 would work fine. What about hosting them somewhere else and using code to display them here? How long is a typical upload on voom?

twangster Posted January 30, 2018 Author Report Share Posted January 30, 2018 How do these 2 compare? Option 1, 800px Option 2, 800px One is 213KB, the other is 108KB. OR... Option 3, 1000px Option 4, 1000px One is 306KB, the other is 119KB Quote Link to comment Share on other sites More sharing options...
Matt Posted January 30, 2018 Report Share Posted January 30, 2018 I cant tell a difference between two. Might be a good question for someone with a Retina display. Quote Link to comment Share on other sites More sharing options...
LetsTryThisPlace Posted January 30, 2018 Report Share Posted January 30, 2018 On my gaming rig, I can barely tell the difference between them. The difference is so small I'm having a hard time deciding which one is better lol. I think the 800 fits the screen better (on a 17.3" screen at 1920x1080) now I should bring it up on a 4K screen but that might be overboard lol. I think for blogging purpose the smaller size 800px is good. Quote Link to comment Share on other sites More sharing options...
JLMoran Posted January 30, 2018 Report Share Posted January 30, 2018 I’m on my phone right now (iPhone 6s Plus), and in landscape mode the 700px image is the first one that fills the screen and has what I’d consider acceptable detail and color balance. Out of the later pictures, the first 800px one looks better than the second. I could tell even before reading the file sizes that the second was more heavily compressed, as it lacked the color saturation and depth of the first one and had less fine detail. No difference I can easily see on the phone between the 800px and 1000px images, at least not without zooming in (which I’m not trusting myself to judge correctly when on pain meds ?).

I hate to break it to you, but I purposely placed the smaller file size image first. Don't believe me? Save both locally and compare.

I thought so, I could tell the difference but it was so small I sat for like 10 minutes and still couldn't decide which was better but sware it might have been the second one but so little the compressed size was fine. What are you using for the compression? Edit** I put my face right up to the screen and it was more obvious but who uses a computer like that lol.

What are you using for the compression? Lightroom Export Function. The smaller file size has "Limit File Size To 150 K", the larger file does not.

LetsTryThisPlace Posted January 30, 2018 Report Share Posted January 30, 2018 I guess I probably stop using raw for photos I take for my blog (although its good for editing). I just looked up a none compressed file from my camera and it is like 10mb yep cant use that for here. lol Quote Link to comment Share on other sites More sharing options...

Shooting in RAW let's me be a poor photographer and fix it later in software. This cruise was just under 30GB for 850 photos. My average photo is ~29MB RAW. HDR images become ~80MB on disk. Typical iPhone shots are 2.5-3MB each so even those need to be resized to something reasonable for web use. LetsTryThisPlace 1 Quote Link to comment Share on other sites More sharing options...

My friend and I have a joke anytime we aren't sure how something came out on the first try "we'll fix it in post" lol. My new phone's camera is only 16 MP compared to my old one that was 20 MP so they don't come out as nice but are much smaller lol. I'm going to play around with Gimp since its free lol hopefully it can pull some good results otherwise need to try Adobe. Quote Link to comment Share on other sites More sharing options...

Neaxan Posted January 30, 2018 Report Share Posted January 30, 2018 I'm fine with 700 pixels, menus or anything else with print might need more. Regarding compression I can't make out much of a difference Quote Link to comment Share on other sites More sharing options...
LetsTryThisPlace Posted February 10, 2018 Report Share Posted February 10, 2018 Noticing on another thread about some people not having LightRoom there is a free editor that I tried recently and does a decent job. Gimp, its not the best by any means but for a free software it does a great job also pixlr is a good web-based option. Quote Link to comment Share on other sites More sharing options...
twangster Posted February 10, 2018 Author Report Share Posted February 10, 2018 Apple app called 'Image Size' for iPhone or iPad seems to work well too if you don't have a computer with you. It's free but ad driven unless you pay $3. EDIT - this app is also available for Android devices.
