A customer scrolling on their phone makes up their mind about your work in about a second, and that judgement happens long before they read a word of your description. The good news is that you do not need an expensive editing subscription to make your craft photos do their job. The editor already built into your phone is enough.

Your phone's built-in editor is more capable than you think

Every photo you take holds far more information than the screen shows you. A shot that looks flat and grey in your camera roll usually has detail lurking in the shadows and highlights, and the free editor on your phone is simply a set of sliders for revealing it.

Paid apps are lovely, but their real value is speed and clever tricks such as selective masking. The bread-and-butter work — brightening, cropping, straightening, warming up something shot under a yellow kitchen bulb — is all there in the tools you already own. For a maker photographing a dozen items in one go, that is genuinely enough.

Try a small experiment: use only your phone's own editor for a fortnight and see how far you get.

Always crop and straighten first

Cropping makes the biggest difference of any single adjustment, and it costs nothing. Before you touch a slider, ask what the photo is for. Square crops suit most marketplace listings, while a taller 4:5 shape works better on social feeds. Choose the shape first, then fill it.

The aim is for your product to dominate the frame. A small item floating in the middle of a wide shot, with a strip of carpet along the bottom, will always look amateur however nicely it is lit. Crop tight and let the piece take up at least two thirds of the image.

• Turn on the grid overlay if your editor has one, then straighten table edges and shelf lines until they sit level.
• Check all four edges for clutter — a trailing cable, a stray mug, the shadow of your arm.
• Leave a slim margin of background around the item rather than cropping right up to its edge.

Straightening matters more than people expect. A shelf line running downhill instantly reads as a rushed photo.

Three moves to get the brightness right

Work in a fixed order: brightness, then highlights and shadows, then contrast. Doing it the other way round is what produces grey, murky pictures.

• Brightness or exposure lifts the whole image. For a cream mug on a white background, this is the slider that turns a grey backdrop white.
• Highlights pulls back the brightest areas so the glaze on a pot keeps its shine instead of blowing out into a white blob.
• Shadows opens up the darker parts — the shaded side of a folded jumper, the inside of a basket — so buyers can see the texture you worked so hard to create.

Only then add a little contrast. Push a slider too far, watch what breaks, and come back towards the middle. That is far quicker than creeping up on the right setting.

Warm it up, cool it down, then stop

Colour is where craft photos go wrong most often, because fabric, yarn, clay and wood all have a colour the buyer cares about. If your mustard wool looks lemon, you will get disappointed messages.

Nearly every built-in editor has a temperature or warmth slider. Household bulbs make photos orange; open shade and grey days make them blue. Nudge the slider the opposite way until the whites in your photo look white rather than creamy or icy. If you have a sheet of white card to hand, prop it in the frame while you shoot and use it as your reference.

Keep saturation gentle. A small push towards richer colour helps, but heavy saturation turns skin tones orange and dye colours unnatural. Compare your edit with the actual item in daylight, and remember that your phone screen is brighter and more colourful than most customer screens.

Sharpen gently and leave room for texture

Sharpening comes last and is the easiest thing to overdo. A little brings out the stitches in a knitted piece or the grain in a wooden bowl; too much creates glowing edges and grainy noise that make handmade work look cheap.

If you shot in dim light, your editor may offer noise reduction. Use it sparingly, because it smooths away exactly the fine texture that makes your work appealing. A slightly grainy photo of real stitches beats a smooth, plasticky one every time.

A simple routine to keep your shop consistent

• Edit in one sitting at the end of a batch rather than as you go, so your eye stays tuned to the same light and the same look.
• Save your edits as a copy, so the original file is always there to return to.
• Aim for the same brightness and white balance across a range, so your shop grid looks as though one person made it.
• Check the finished photo at thumbnail size — if you cannot tell what the item is, crop again.
• View your edits on a second screen, or in daylight, before uploading anything.

Small, consistent adjustments made quickly will always beat an hour spent fiddling with one photo. Get the crop right, get the whites white and keep the colour honest, and your work will do the selling for you.
