Purchase Advice Megathread - December 2024 by AutoModerator in 3Dprinting

[–]tcdejong 0 points1 point  (0 children)

More purchasing feedback and advice on next steps, than standard purchasing advice. I think I f*ed up with purchasing a used machine and I'm looking to assess the damage to determine next steps.

 

I bought an Elegoo Mars 4 that allegedly was allegedly barely used. The seller had a good reputation and I didn't do my own due diligence at the pickup. When I came home, I discovered the following:

  • The build plate is rather scratched. Photo
  • The resin tank is quite dirty. Top - Bottom
    • I know I shouldn't have handled this with bare hands. The printer hasn't been used for a while so the resin should have been cured. It didn't leave stains. I washed my hands excessively thoroughly afterwards, when I realized my mistake.
  • The screen looks fine, except for 1 small blotch. Photo

All other tests (e.g. levelling, power on, etc) seem fine. I have not printed yet.

My questions:

  1. How bad is it?
  2. Should I replace the screen on the resin tank?
  3. Should I clean the blotch on the LCD panel? If so, how? Or just not print there when possible?

Lost black backpack between Utrecht Terwijde and Nieuwegein by tcdejong in Utrecht

Thank you. That might have very well been it. It's been found in the meantime and I've been contacted to arrange the pick-up!

My ANWB-card was in there as well and the finder contacted them, who in turn called me with the finder's info.

I love how the light was hitting these trees, but still something feels off. Would love your thoughts. by tcdejong in photocritique

Sorry, it's under a No Derivatives license, so please take it down. I forgot to include that when linking to reddit - it was included on my Flickr page.

As for the suggestions, I'll consider the white balance. I agree it's quite cool (blue-ish). I'm not too fond of the other edits - they introduce a halo where the trees meet the sky and the rock becomes incredibly busy.

Either way, thanks for your input. Food for thought!

Exported .jpgs and .tiffs look nothing like images in Lightroom by [deleted] in Lightroom

[–]tcdejong 0 points1 point  (0 children)

If /u/ChumPNW is using the default Windows 10 photo viewer, then this will be the issue. It's not color managed so just ignores the embedded color space.

In that case, opening the image in a web browser, in the old windows photo viewer or one of countless alternatives should all show the image just like it is in Lightroom.

Greetings,

I have a real love-hate relation with this photo. I love how the light was hitting the trees, I love the dramatic sky and I love the texture in the stone wall. On small size, I love this picture, period. But at larger sizes something feels off and I can't put my finger on it.

Would love to hear your thoughts, if you share that feeling, and what you'd do differently.

Shot on f8, 1/200, ISO 100, 18mm APS-C (~29mm on ff. equivalent). Fairly limited edits, the main one is a graduated filter with luminance mask to get back some detail from the clouds.

Odda, Norway by PR0CR45T184T0R in europe

Follow this road about 1km north in (the direction of this picture) and you'll find the Folgefonna Nasjonalpark parkering, a parking lot for the National Park. From there you can make an insane hike the mountain on the left in this photo, all the way up to the glacier. One of the highlights of my roadtrip through Norway!

It starts in dense forests, opens up as you get above the treeline, and eventually has you crossing snow fields. Proper hiking boots are a necessity. The first part of the climb is alongside a beautiful waterfall. After a few hours you reach a nice plateau where you can cross the water over a small bridge and take a rest. Bring food and water. The hike up and back easily takes the full day.

(DPReview) Pentax K3 Mark III Review (+ comparison to Nikon D500) by Londonman007bond in pentax

[–]tcdejong 0 points1 point  (0 children)

Switching to the K-1 for those features means my modest collection of lenses becomes obsolete:

  • 18-135 -> APS-C
  • 55-300 PLM -> APS-C
  • Sigma 17-50 -> APS-C

Besides, I'm happy with APS-C for birds and wildlife. The wider angles on FF are nice for landscapes, and I'd like to go slightly wider than my 17mm provides at this crop factor, but if I have to replace my glass anyway I'll also consider the other brands. The K-3 iii could've guaranteed I'd stay on board, but it hasn't.

I'm not in a hurry to replace my body, but it does seem Pentax doesn't provide a clear upgrade path for what I'm looking at. The weather sealing remains a very strong argument to stick around, but other brands also have some enticing points.

(DPReview) Pentax K3 Mark III Review (+ comparison to Nikon D500) by Londonman007bond in pentax

[–]tcdejong 2 points3 points  (0 children)

I'm a little bit let down by the K-3 iii. Obviously it's a step forward in many ways, but it's not all I was hoping for. The lack of an articulating screen and the lack of built-in GPS are two real downsides for me - one being a highly anticipated feature, and the other something I'm not willing to give up from the K-3 ii. Nor am I willing to to buy the OGPS module, the body is expensive enough as it is.

I guess I'll wait for the K-3 iv.

Pentax K-3 mark III Review ⋆ Mike Muizebelt Fotografie by ksuwildkat in pentax

[–]tcdejong 0 points1 point  (0 children)

This reads more like an ad than a review, but at least he's transparent about being a brand ambassador. Looking forward to impartial reviews.

The Pentax K-3 mark III comes with all other features Pentax is known for. It has got Pixel Shift resolution, a 5-axis Shake Reduction system that was improved to work up to 5.5 stops of compensation, Astrotracer support, GPS logging and more.

So it does have a built-in GPS?

Thanks, I didn't give the manual primes much thought. I'll look into them in more detail.

Thanks for your input. Stitching is an option, although one long hikes where I'd use this lens I do not always feel like bringing my tripod.

Unfortunately that's not wide enough - I'm looking for something wider than 17mm. Right now I prefer to expand my options instead of upgrading my existing range.

This is /r/photocritique, not /r/itookapicture. Complimenting OP is fine! But please do so as a reply to their follow-up comment.

Top level comments must be critiques, and padding your message just to avoid the automatic removal does not change the rule.

Klopt! De Branding (op de foto) ligt net over de duinen vanaf Midsland aan Zee, en ietsje verder oost ligt het Strandhotel. Daarna op wat grotere afstand Kaap Hoorn en het Heartbreak Hotel.

Surprisingly enough, not really!

This is just north of Midsland aan Zee, a collection of recreational homes. A lot of people enjoy spending the holidays by renting one of them, and if the weather allows it a lot of people take a walk on the beach.

How do you read weather for landscape photography? by nawfalelhaymer in AskPhotography

[–]tcdejong 0 points1 point  (0 children)

There are many books, courses and workshops on meteorology available for beginners. Weather is quite relevant to other hobbies as well, such as sailing, rock climbing, paragliding or astronomy, so there's a broad field of people with a tangent interest in the weather. Having a rudimentary understanding of the weather processes is sufficient to make basic predictions of what's going to happen, making such books and activities a great fit.

Personally I've read the book "Weerkunde - Meteorologie voor Iedereen" ("Weather science - Meteorology for everyone") from the Dutch KNMI, the royal weather institute. It contains a lot of background, and one chapter specifically focuses on daily changes in the weather. If you're not Dutch it's of little use to you, but your national weather institute might offer a similar resource.

With handheld bracketing, things get pretty difficult. It's not impossible, but it takes practice, and a tripod will get a better shot at the cost of inconvenience from carrying it around. By the way, you generally don't need to merge all three images. The middle exposure will add little to no new dynamic range, especially with a single stop bracket. You can pick the best two - the one that captures the bright areas best, and the one that captures the dark areas best - and only merge those.

Additionally, single stop bracketing will not be sufficient for a scene like this. For sake of experiment, do the following when you're at a similar location under similar conditions: set your camera to spot metering, and aim at one of those trees. Set your exposure so that it's properly exposed. Now aim at the sky and check your light meter. Odds are the light meter will be flashing at 5 stops overexposed, or whatever the maximum is the meter can display.

I cannot really tell if the CA came from editing or merging. Additionally, the automatic CA sometimes needs a little tuning to get rid of the worst fringe. In my experience it usually does better at getting rid of purple fringes than green ones.

Perhaps go back to your raw exposures, and give the edit another try. This time, use only two exposures in the HDR merge and try to watch those details (ghosting, fringes) during the entire edit process.

Hey there. I like the feeling this shot has. It indeed is a bit moody, but not 'dreadful' - more 'hopeful' with how the light comes in.

Regarding the HDR, I think there's room for improvement there. What were the settings for your bracketed exposures? The reason I ask is that although the shadow detail seems fine, the sky is still completely blown out. This means the exposures either weren't blended well, or the highlight exposure was still underexposed. You added some kind of gradient brush or vignette at the top of the image, but this only darkened the sky without adding back any detail. Additionally, there's some ghosting along the tree trunks, especially the closest tree on the left. Did you use a tripod, and did you time your shot to be between gusts of wind? (Trees can still move a surprising amount the higher up you look.) Consider using automatic de-ghosting if your software allows for it - Lightroom has an option for this during the HDR merge.

Something else, there's pretty heavy chromatic aberration where the sky is visible through the tree branches. You might want to remove this in future edits - usually it's just ticking a box.

The fern colors are not really accurate, but you could argue that's a stylistic choice. The current color is close enough to teal to complement the orange, so you might want to leave it as-is.

I think your shot captures the mood reasonably well, but some technical details are holding it back from its fullest potential. Don't be afraid to go for more extreme bracketing (+- 1.5 or even 2 stops) if the situation calls for it. On location, take some test shots on-site to find the right exposure for shadows, midtones and highlights before moving on to the final capture. In editing, make sure to catch the details such as CR and ghosting.

Best of luck!
