file management – Converting old photos to JPEGs in Lightroom?

This is a question about photo management in Lightroom Classic – I pretty much know what I’d like to achieve, but I’m bit uneasy to experiment, knowing how flimsy and buggy LR can be. As such, I’m eager to hear from people with first-hand experience in similar operations.

I use a single catalogue, ~30k photos, ~300GB on disk. I’ve noticed recently that I primarily operate on last 2-3y worth of photos, not touching older photos. As such, it’d make sense to “flatten” those older photos to JPEGs; I’d save some disk space and make it easier for myself to browse the photos across different devices (DNGs are routinely rendered in a weird manner the moment I step outside of my win10 ecosystem :). I’d prefer to stick to single catalogue for my photos. Is there a sensible way of converting the photos “in place”, preserving all of the metadata the original photos have? The edit history would obviously be lost, but I’m okay with that. If that kind of process is relatively bug-free, I could imagine yearly move of the cut-off point, to ditch RAWs from yet another year.

Anyone doing something like that? Any gotchas or ways you’ve seen this explode?

image quality – How can I automatically convert Sony RAW (ARW) to JPEGs as good as the camera creates itself?

I recently found myself in the same situation, took some RAW shots, not RAW + Jpeg, and now have a ton of photos that I need to improve in order to show anyone.

I’ve tried a small handful of programs so far- Imaging Edge, Fotor, FastStone Image Viewer.

Here’s what I’ve found-

Imaging Edge works very well. It’s made by Sony and going by the logic that “Sony knows Sony”, I trust that it knows how to work with it’s own camera’s images. And the results look pretty good. It’s also reasonably fast, 500 pictures took around 30-40 minutes.

FastStone Viewer was nearly as good. I used the “Quality = 100” setting, everything else default. It was as fast, or nearly as fast, as Imaging Edge. The quality was nearly indistinguishable. The jpeg file sizes were much larger, around double the size. FastStone has some other options that could be tweaked that might make more of a difference, but I didn’t play with them.

Fotor was not very good. It was VERY slow, taking about 24 hours to convert the photos (it’s hard to tell exactly how long, because my laptop kept sleeping after a few hours, and I’m not sure the processing was working in the background.) Also, the resulting photos were very ‘noisy’. Some looked ok at the regular size, but when I zoomed in on the photo, there were a LOT of extra color and pixels that distracted from the image. Would not recommend this one.

So, as Michael C says, try the Sony program and see what happens. Imaging Edge is actually three programs (viewer, editor and camera remote control). It’s the viewer that I used to batch-output my photos.

Hope that helps.

exploit – Are PPM or BMP images safer than JPEGs or PNGs?

The question is: what makes a PPM file safer? Is it because there’s no room to hide a payload, without becoming too noticeable at first sight?

No. You might argue that for plain text files (not strictly true, but that would allow to vet most of them).

However, for most images, you wouldn’t be able to discern the payload from the image data.

Or is it because the format is so simple to parse, that we can suppose our software will be less likely to be vulnerable, when opening such files? And most importantly, is it even true that we can consider PPM files (and maybe also BMP) to be safer than, say, more complex formats like JPEG or PNG?

Exactly. Decompression routines are complex. Code rendering formats like JPEG or PNG have an higher chance of having a vulnerability on there. Still very unlikely, albeit there were a few of them (e.g. JPEG 2000 one years back), but it is higher than for a dumber format.

photoshop – Best way to process an HDR image from JPEGs

By far the simplest way is to use an HDR-specific app or plugin.

I’ve used both Aurora HDR & the old (used to be freeware) Nik Collection plugin HDR Efex Pro 2, both with reasonable degree of success. Both can take either a single input image or a bracketed set of exposures – even hand-held so long as there’s not too much movement, as they will auto-align.
No doubt there are many alternatives to those you could try too.

Photoshop itself I’ve always thought to be quite poor at HDR compared to these dedicated apps. I don’t use Lightroom, but I can’t imagine it being a great deal better.

plugins – Create progressive JPEGs with intermediate image sizes

I am learning to write themes and plugins to create my own WordPress page.

The images converted by WordPress during download work well in most cases, but there is a problem. Suppose I upload a 5k + photo, it is converted to several sizes (wide versions 2560px, 1920px, 1280px, etc.) for a responsive web – the resulting JPEGs are not progressive. This means that, in some extreme cases, a full size photo is faster than the converted version! Not to mention, I have no control over the quality of the compression – not overall, let alone the size or the image.

Although WordPress makes improvements to responsive images with version 5.3, it is pretty smooth, and so far, they leave the process control to the plug-ins.

However, almost all image optimization plug-ins want to sell you their web service. There is no plug-in that works locally that I have found.

Is there a way to control this process? I do not master WordPress or PHP, but I understand the principles, as well as the OOP, etc. I'm sure I would be able to understand the details, but I need to know where to start at least.
Can I add this functionality to functions.php or do I need to create a plug-in?

Thank you

Photo Management – What can Hasselblad Phocus do with JPEGs?

I started using Hasselblad Phocus (3.3.6) to organize and clean my photo collection. After shooting mainly in JPEG, the items of the menu White Balance and Noise Filter are missing. I can not find anything in the documentation. Is it really true that these menu items are only active for RAW images?
